## The problem
|
||
|
|
||
|
You want to use [jest][] to write tests that assert various things about the
|
||
|
state of a DOM. As part of that goal, you want to avoid all the repetitive
|
||
|
patterns that arise in doing so. Checking for an element's attributes, its text
|
||
|
content, its css classes, you name it.
|
||
|
|
||
|
## This solution
|
||
|
|
||
|
The `@testing-library/jest-dom` library provides a set of custom jest matchers
|
||
|
that you can use to extend jest. These will make your tests more declarative,
|
||
|
clear to read and to maintain.

## Installation
|
||
|
|
||
|
This module is distributed via [npm][npm] which is bundled with [node][node] and
|
||
|
should be installed as one of your project's `devDependencies`:
|
||
|
|
||
|
```
|
||
|
npm install --save-dev @testing-library/jest-dom
|
||
|
```
|
||
|
|
||
|
or
|
||
|
|
||
|
for installation with [yarn](https://yarnpkg.com/) package manager.
|
||
|
|
||
|
```
|
||
|
yarn add --dev @testing-library/jest-dom
|
||
|
```
|
||
|
|
||
|
> Note: We also recommend installing the jest-dom eslint plugin which provides
|
||
|
> auto-fixable lint rules that prevent false positive tests and improve test
|
||
|
> readability by ensuring you are using the right matchers in your tests. More
|
||
|
> details can be found at
|
||
|
> [eslint-plugin-jest-dom](https://github.com/testing-library/eslint-plugin-jest-dom).
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
Import `@testing-library/jest-dom` once (for instance in your [tests setup
|
||
|
file][]) and you're good to go:
|
||
|
|
||
|
[tests setup file]:
|
||
|
https://jestjs.io/docs/en/configuration.html#setupfilesafterenv-array
|
||
|
|
||
|
```javascript
|
||
|
// In your own jest-setup.js (or any other name)
|
||
|
import '@testing-library/jest-dom'
|
||
|
|
||
|
// In jest.config.js add (if you haven't already)
|
||
|
setupFilesAfterEnv: ['<rootDir>/jest-setup.js']
|
||
|
```
|
||
|
|
||
|
### With TypeScript
|
||
|
|
||
|
If you're using TypeScript, make sure your setup file is a `.ts` and not a `.js`
|
||
|
to include the necessary types.
|
||
|
|
||
|
You will also need to include your setup file in your `tsconfig.json` if you
|
||
|
haven't already:
|
||
|
|
||
|
```json
|
||
|
// In tsconfig.json
|
||
|
"include": [
|
||
|
...
|
||
|
"./jest-setup.ts"
|
||
|
],
|
||
|
```
|
||
|
|
||
|
## Custom matchers
|
||
|
|
||
|
`@testing-library/jest-dom` can work with any library or framework that returns
|
||
|
DOM elements from queries. The custom matcher examples below are written using
|
||
|
matchers from `@testing-library`'s suite of libraries (e.g. `getByTestId`,
|
||
|
`queryByTestId`, `getByText`, etc.)
|
||
|
|
||
|
### `toBeDisabled`
|
||
|
|
||
|
```typescript
|
||
|
toBeDisabled()
|
||
|
```
|
||
|
|
||
|
This allows you to check whether an element is disabled from the user's
|
||
|
perspective. According to the specification, the following elements can be
|
||
|
[disabled](https://html.spec.whatwg.org/multipage/semantics-other.html#disabled-elements):
|
||
|
`button`, `input`, `select`, `textarea`, `optgroup`, `option`, `fieldset`, and
|
||
|
custom elements.
|
||
|
|
||
|
This custom matcher considers an element as disabled if the element is among the
|
||
|
types of elements that can be disabled (listed above), and the `disabled`
|
||
|
attribute is present. It will also consider the element as disabled if it's
|
||
|
inside a parent form element that supports being disabled and has the `disabled`
|
||
|
attribute present.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<button data-testid="button" type="submit" disabled>submit</button>
|
||
|
<fieldset disabled><input type="text" data-testid="input" /></fieldset>
|
||
|
<a href="..." disabled>link</a>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('button')).toBeDisabled()
|
||
|
expect(getByTestId('input')).toBeDisabled()
|
||
|
expect(getByText('link')).not.toBeDisabled()
|
||
|
```
|
||
|
|
||
|
> This custom matcher does not take into account the presence or absence of the
|
||
|
> `aria-disabled` attribute. For more on why this is the case, check
|
||
|
> [#144](https://github.com/testing-library/jest-dom/issues/144).
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeEnabled`
|
||
|
|
||
|
```typescript
|
||
|
toBeEnabled()
|
||
|
```
|
||
|
|
||
|
This allows you to check whether an element is not disabled from the user's
|
||
|
perspective.
|
||
|
|
||
|
It works like `not.toBeDisabled()`. Use this matcher to avoid double negation in
|
||
|
your tests.
|
||
|
|
||
|
> This custom matcher does not take into account the presence or absence of the
|
||
|
> `aria-disabled` attribute. For more on why this is the case, check
|
||
|
> [#144](https://github.com/testing-library/jest-dom/issues/144).
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeEmptyDOMElement`
|
||
|
|
||
|
```typescript
|
||
|
toBeEmptyDOMElement()
|
||
|
```
|
||
|
|
||
|
This allows you to assert whether an element has no visible content for the
|
||
|
user. It ignores comments but will fail if the element contains white-space.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<span data-testid="not-empty"><span data-testid="empty"></span></span>
|
||
|
<span data-testid="with-whitespace"> </span>
|
||
|
<span data-testid="with-comment"><!-- comment --></span>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('empty')).toBeEmptyDOMElement()
|
||
|
expect(getByTestId('not-empty')).not.toBeEmptyDOMElement()
|
||
|
expect(getByTestId('with-whitespace')).not.toBeEmptyDOMElement()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeInTheDocument`
|
||
|
|
||
|
```typescript
|
||
|
toBeInTheDocument()
|
||
|
```
|
||
|
|
||
|
This allows you to assert whether an element is present in the document or not.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<span data-testid="html-element"><span>Html Element</span></span>
|
||
|
<svg data-testid="svg-element"></svg>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(
|
||
|
getByTestId(document.documentElement, 'html-element'),
|
||
|
).toBeInTheDocument()
|
||
|
expect(getByTestId(document.documentElement, 'svg-element')).toBeInTheDocument()
|
||
|
expect(
|
||
|
queryByTestId(document.documentElement, 'does-not-exist'),
|
||
|
).not.toBeInTheDocument()
|
||
|
```
|
||
|
|
||
|
> Note: This matcher does not find detached elements. The element must be added
|
||
|
> to the document to be found by toBeInTheDocument. If you desire to search in a
|
||
|
> detached element please use: [`toContainElement`](#tocontainelement)
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeInvalid`
|
||
|
|
||
|
```typescript
|
||
|
toBeInvalid()
|
||
|
```
|
||
|
|
||
|
This allows you to check if an element, is currently invalid.
|
||
|
|
||
|
An element is invalid if it has an
|
||
|
[`aria-invalid` attribute](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_aria-invalid_attribute)
|
||
|
with no value or a value of `"true"`, or if the result of
|
||
|
[`checkValidity()`](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/HTML5/Constraint_validation)
|
||
|
is `false`.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<input data-testid="no-aria-invalid" />
|
||
|
<input data-testid="aria-invalid" aria-invalid />
|
||
|
<input data-testid="aria-invalid-value" aria-invalid="true" />
|
||
|
<input data-testid="aria-invalid-false" aria-invalid="false" />
|
||
|
|
||
|
<form data-testid="valid-form">
|
||
|
<input />
|
||
|
</form>
|
||
|
|
||
|
<form data-testid="invalid-form">
|
||
|
<input required />
|
||
|
</form>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('no-aria-invalid')).not.toBeInvalid()
|
||
|
expect(getByTestId('aria-invalid')).toBeInvalid()
|
||
|
expect(getByTestId('aria-invalid-value')).toBeInvalid()
|
||
|
expect(getByTestId('aria-invalid-false')).not.toBeInvalid()
|
||
|
|
||
|
expect(getByTestId('valid-form')).not.toBeInvalid()
|
||
|
expect(getByTestId('invalid-form')).toBeInvalid()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeRequired`
|
||
|
|
||
|
```typescript
|
||
|
toBeRequired()
|
||
|
```
|
||
|
|
||
|
This allows you to check if a form element is currently required.
|
||
|
|
||
|
An element is required if it is having a `required` or `aria-required="true"`
|
||
|
attribute.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<input data-testid="required-input" required />
|
||
|
<input data-testid="aria-required-input" aria-required="true" />
|
||
|
<input data-testid="conflicted-input" required aria-required="false" />
|
||
|
<input data-testid="aria-not-required-input" aria-required="false" />
|
||
|
<input data-testid="optional-input" />
|
||
|
<input data-testid="unsupported-type" type="image" required />
|
||
|
<select data-testid="select" required></select>
|
||
|
<textarea data-testid="textarea" required></textarea>
|
||
|
<div data-testid="supported-role" role="tree" required></div>
|
||
|
<div data-testid="supported-role-aria" role="tree" aria-required="true"></div>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('required-input')).toBeRequired()
|
||
|
expect(getByTestId('aria-required-input')).toBeRequired()
|
||
|
expect(getByTestId('conflicted-input')).toBeRequired()
|
||
|
expect(getByTestId('aria-not-required-input')).not.toBeRequired()
|
||
|
expect(getByTestId('optional-input')).not.toBeRequired()
|
||
|
expect(getByTestId('unsupported-type')).not.toBeRequired()
|
||
|
expect(getByTestId('select')).toBeRequired()
|
||
|
expect(getByTestId('textarea')).toBeRequired()
|
||
|
expect(getByTestId('supported-role')).not.toBeRequired()
|
||
|
expect(getByTestId('supported-role-aria')).toBeRequired()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeValid`
|
||
|
|
||
|
```typescript
|
||
|
toBeValid()
|
||
|
```
|
||
|
|
||
|
This allows you to check if the value of an element, is currently valid.
|
||
|
|
||
|
An element is valid if it has no
|
||
|
[`aria-invalid` attribute](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_aria-invalid_attribute)s
|
||
|
or an attribute value of `"false"`. The result of
|
||
|
[`checkValidity()`](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/HTML5/Constraint_validation)
|
||
|
must also be `true` if it's a form element.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<input data-testid="no-aria-invalid" />
|
||
|
<input data-testid="aria-invalid" aria-invalid />
|
||
|
<input data-testid="aria-invalid-value" aria-invalid="true" />
|
||
|
<input data-testid="aria-invalid-false" aria-invalid="false" />
|
||
|
|
||
|
<form data-testid="valid-form">
|
||
|
<input />
|
||
|
</form>
|
||
|
|
||
|
<form data-testid="invalid-form">
|
||
|
<input required />
|
||
|
</form>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('no-aria-invalid')).toBeValid()
|
||
|
expect(getByTestId('aria-invalid')).not.toBeValid()
|
||
|
expect(getByTestId('aria-invalid-value')).not.toBeValid()
|
||
|
expect(getByTestId('aria-invalid-false')).toBeValid()
|
||
|
|
||
|
expect(getByTestId('valid-form')).toBeValid()
|
||
|
expect(getByTestId('invalid-form')).not.toBeValid()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeVisible`
|
||
|
|
||
|
```typescript
|
||
|
toBeVisible()
|
||
|
```
|
||
|
|
||
|
This allows you to check if an element is currently visible to the user.
|
||
|
|
||
|
An element is visible if **all** the following conditions are met:
|
||
|
|
||
|
- it is present in the document
|
||
|
- it does not have its css property `display` set to `none`
|
||
|
- it does not have its css property `visibility` set to either `hidden` or
|
||
|
`collapse`
|
||
|
- it does not have its css property `opacity` set to `0`
|
||
|
- its parent element is also visible (and so on up to the top of the DOM tree)
|
||
|
- it does not have the
|
||
|
[`hidden`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden)
|
||
|
attribute
|
||
|
- if `<details />` it has the `open` attribute
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<div data-testid="zero-opacity" style="opacity: 0">Zero Opacity Example</div>
|
||
|
<div data-testid="visibility-hidden" style="visibility: hidden">
|
||
|
Visibility Hidden Example
|
||
|
</div>
|
||
|
<div data-testid="display-none" style="display: none">Display None Example</div>
|
||
|
<div style="opacity: 0">
|
||
|
<span data-testid="hidden-parent">Hidden Parent Example</span>
|
||
|
</div>
|
||
|
<div data-testid="visible">Visible Example</div>
|
||
|
<div data-testid="hidden-attribute" hidden>Hidden Attribute Example</div>
|
||
|
<details>
|
||
|
<summary>Title of hidden text</summary>
|
||
|
Hidden Details Example
|
||
|
</details>
|
||
|
<details open>
|
||
|
<summary>Title of visible text</summary>
|
||
|
<div>Visible Details Example</div>
|
||
|
</details>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByText('Zero Opacity Example')).not.toBeVisible()
|
||
|
expect(getByText('Visibility Hidden Example')).not.toBeVisible()
|
||
|
expect(getByText('Display None Example')).not.toBeVisible()
|
||
|
expect(getByText('Hidden Parent Example')).not.toBeVisible()
|
||
|
expect(getByText('Visible Example')).toBeVisible()
|
||
|
expect(getByText('Hidden Attribute Example')).not.toBeVisible()
|
||
|
expect(getByText('Hidden Details Example')).not.toBeVisible()
|
||

expect(getByText('Visible Details Example')).toBeVisible()
|
||
|
```

### `toContainElement`
|
||
|
|
||
|
```typescript
|
||
|
toContainElement(element: HTMLElement | SVGElement | null)
|
||
|
```
|
||
|
|
||
|
This allows you to assert whether an element contains another element as a
|
||
|
descendant or not.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<span data-testid="ancestor"><span data-testid="descendant"></span></span>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const ancestor = getByTestId('ancestor')
|
||
|
const descendant = getByTestId('descendant')
|
||
|
const nonExistantElement = getByTestId('does-not-exist')
|
||
|
|
||
|
expect(ancestor).toContainElement(descendant)
|
||
|
expect(descendant).not.toContainElement(ancestor)
|
||
|
expect(ancestor).not.toContainElement(nonExistantElement)
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toContainHTML`
|
||
|
|
||
|
```typescript
|
||
|
toContainHTML(htmlText: string)
|
||
|
```
|
||
|
|
||
|
Assert whether a string representing a HTML element is contained in another
|
||
|
element. The string should contain valid html, and not any incomplete html.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<span data-testid="parent"><span data-testid="child"></span></span>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
// These are valid uses
|
||
|
expect(getByTestId('parent')).toContainHTML('<span data-testid="child"></span>')
|
||
|
expect(getByTestId('parent')).toContainHTML('<span data-testid="child" />')
|
||
|
expect(getByTestId('parent')).not.toContainHTML('<br />')
|
||
|
|
||
|
// These won't work
|
||
|
expect(getByTestId('parent')).toContainHTML('data-testid="child"')
|
||
|
expect(getByTestId('parent')).toContainHTML('data-testid')
|
||
|
expect(getByTestId('parent')).toContainHTML('</span>')
|
||
|
```

### `toHaveAccessibleDescription`
|
||
|
|
||
|
```typescript
|
||
|
toHaveAccessibleDescription(expectedAccessibleDescription?: string | RegExp)
|
||
|
```
|
||
|
|
||
|
This allows you to assert that an element has the expected
|
||
|
[accessible description](https://w3c.github.io/accname/).
|
||
|
|
||
|
You can pass the exact string of the expected accessible description, or you can
|
||
|
make a partial match passing a regular expression, or by using
|
||
|
[expect.stringContaining](https://jestjs.io/docs/en/expect.html#expectnotstringcontainingstring)/[expect.stringMatching](https://jestjs.io/docs/en/expect.html#expectstringmatchingstring-regexp).
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<a
|
||
|
data-testid="link"
|
||
|
href="/"
|
||
|
aria-label="Home page"
|
||
|
title="A link to start over"
|
||
|
>Start</a
|
||
|
>
|
||
|
<a data-testid="extra-link" href="/about" aria-label="About page">About</a>
|
||
|
<img src="avatar.jpg" data-testid="avatar" alt="User profile pic" />
|
||
|
<img
|
||
|
src="logo.jpg"
|
||
|
data-testid="logo"
|
||
|
alt="Company logo"
|
||
|
aria-describedby="t1"
|
||
|
/>
|
||
|
<span id="t1" role="presentation">The logo of Our Company</span>
|
||
|
```
|
||
|
|
||
|
```js
|
||
|
expect(getByTestId('link')).toHaveAccessibleDescription()
|
||
|
expect(getByTestId('link')).toHaveAccessibleDescription('A link to start over')
|
||
|
expect(getByTestId('link')).not.toHaveAccessibleDescription('Home page')
|
||
|
expect(getByTestId('extra-link')).not.toHaveAccessibleDescription()
|
||
|
expect(getByTestId('avatar')).not.toHaveAccessibleDescription()
|
||
|
expect(getByTestId('logo')).not.toHaveAccessibleDescription('Company logo')
|
||
|
expect(getByTestId('logo')).toHaveAccessibleDescription(
|
||
|
'The logo of Our Company',
|
||
|
)
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toHaveAccessibleName`
|
||
|
|
||
|
```typescript
|
||
|
toHaveAccessibleName(expectedAccessibleName?: string | RegExp)
|
||
|
```
|
||
|
|
||
|
This allows you to assert that an element has the expected
|
||
|
[accessible name](https://w3c.github.io/accname/). It is useful, for instance,
|
||
|
to assert that form elements and buttons are properly labelled.
|
||
|
|
||
|
You can pass the exact string of the expected accessible name, or you can make a
|
||
|
partial match passing a regular expression, or by using
|
||
|
[expect.stringContaining](https://jestjs.io/docs/en/expect.html#expectnotstringcontainingstring)/[expect.stringMatching](https://jestjs.io/docs/en/expect.html#expectstringmatchingstring-regexp).
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<img data-testid="img-alt" src="" alt="Test alt" />
|
||
|
<img data-testid="img-empty-alt" src="" alt="" />
|
||
|
<svg data-testid="svg-title"><title>Test title</title></svg>
|
||
|
<button data-testid="button-img-alt"><img src="" alt="Test" /></button>
|
||
|
<p><img data-testid="img-paragraph" src="" alt="" /> Test content</p>
|
||
|
<button data-testid="svg-button"><svg><title>Test</title></svg></p>
|
||
|
<div><svg data-testid="svg-without-title"></svg></div>
|
||
|
<input data-testid="input-title" title="test" />
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('img-alt')).toHaveAccessibleName('Test alt')
|
||
|
expect(getByTestId('img-empty-alt')).not.toHaveAccessibleName()
|
||
|
expect(getByTestId('svg-title')).toHaveAccessibleName('Test title')
|
||
|
expect(getByTestId('button-img-alt')).toHaveAccessibleName()
|
||
|
expect(getByTestId('img-paragraph')).not.toHaveAccessibleName()
|
||
|
expect(getByTestId('svg-button')).toHaveAccessibleName()
|
||
|
expect(getByTestId('svg-without-title')).not.toHaveAccessibleName()
|
||
|
expect(getByTestId('input-title')).toHaveAccessibleName()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toHaveAttribute`
|
||
|
|
||
|
```typescript
|
||
|
toHaveAttribute(attr: string, value?: any)
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given element has an attribute or not. You
|
||
|
can also optionally check that the attribute has a specific expected value or
|
||
|
partial match using
|
||
|
[expect.stringContaining](https://jestjs.io/docs/en/expect.html#expectnotstringcontainingstring)/[expect.stringMatching](https://jestjs.io/docs/en/expect.html#expectstringmatchingstring-regexp)
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<button data-testid="ok-button" type="submit" disabled>ok</button>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const button = getByTestId('ok-button')
|
||
|
|
||
|
expect(button).toHaveAttribute('disabled')
|
||
|
expect(button).toHaveAttribute('type', 'submit')
|
||
|
expect(button).not.toHaveAttribute('type', 'button')
|
||
|
|
||
|
expect(button).toHaveAttribute('type', expect.stringContaining('sub'))
|
||
|
expect(button).toHaveAttribute('type', expect.not.stringContaining('but'))
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toHaveClass`
|
||
|
|
||
|
```typescript
|
||
|
toHaveClass(...classNames: string[], options?: {exact: boolean})
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given element has certain classes within
|
||
|
its `class` attribute.
|
||
|
|
||
|
You must provide at least one class, unless you are asserting that an element
|
||
|
does not have any classes.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<button data-testid="delete-button" class="btn extra btn-danger">
|
||
|
Delete item
|
||
|
</button>
|
||
|
<button data-testid="no-classes">No Classes</button>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const deleteButton = getByTestId('delete-button')
|
||
|
const noClasses = getByTestId('no-classes')
|
||
|
|
||
|
expect(deleteButton).toHaveClass('extra')
|
||
|
expect(deleteButton).toHaveClass('btn-danger btn')
|
||
|
expect(deleteButton).toHaveClass('btn-danger', 'btn')
|
||
|
expect(deleteButton).not.toHaveClass('btn-link')
|
||
|
|
||
|
expect(deleteButton).toHaveClass('btn-danger extra btn', {exact: true}) // to check if the element has EXACTLY a set of classes
|
||
|
expect(deleteButton).not.toHaveClass('btn-danger extra', {exact: true}) // if it has more than expected it is going to fail
|
||
|
|
||
|
expect(noClasses).not.toHaveClass()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toHaveFocus`
|
||
|
|
||
|
```typescript
|
||
|
toHaveFocus()
|
||
|
```
|
||
|
|
||
|
This allows you to assert whether an element has focus or not.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<div><input type="text" data-testid="element-to-focus" /></div>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const input = getByTestId('element-to-focus')
|
||
|
|
||
|
input.focus()
|
||
|
expect(input).toHaveFocus()
|
||
|
|
||
|
input.blur()
|
||
|
expect(input).not.toHaveFocus()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toHaveFormValues`
|
||
|
|
||
|
```typescript
|
||
|
toHaveFormValues(expectedValues: {
|
||
|
[name: string]: any
|
||
|
})
|
||
|
```
|
||
|
|
||
|
This allows you to check if a form or fieldset contains form controls for each
|
||
|
given name, and having the specified value.
|
||
|
|
||
|
> It is important to stress that this matcher can only be invoked on a [form][]
|
||
|
> or a [fieldset][] element.
|
||
|
>
|
||
|
> This allows it to take advantage of the [.elements][] property in `form` and
|
||
|
> `fieldset` to reliably fetch all form controls within them.
|
||
|
>
|
||
|
> This also avoids the possibility that users provide a container that contains
|
||
|
> more than one `form`, thereby intermixing form controls that are not related,
|
||
|
> and could even conflict with one another.
|
||
|
|
||
|
This matcher abstracts away the particularities with which a form control value
|
||
|
is obtained depending on the type of form control. For instance, `<input>`
|
||
|
elements have a `value` attribute, but `<select>` elements do not. Here's a list
|
||
|
of all cases covered:
|
||
|
|
||
|
- `<input type="number">` elements return the value as a **number**, instead of
|
||
|
a string.
|
||
|
- `<input type="checkbox">` elements:
|
||
|
- if there's a single one with the given `name` attribute, it is treated as a
|
||
|
**boolean**, returning `true` if the checkbox is checked, `false` if
|
||
|
unchecked.
|
||
|
- if there's more than one checkbox with the same `name` attribute, they are
|
||
|
all treated collectively as a single form control, which returns the value
|
||
|
as an **array** containing all the values of the selected checkboxes in the
|
||
|
collection.
|
||
|
- `<input type="radio">` elements are all grouped by the `name` attribute, and
|
||
|
such a group treated as a single form control. This form control returns the
|
||
|
value as a **string** corresponding to the `value` attribute of the selected
|
||
|
radio button within the group.
|
||
|
- `<input type="text">` elements return the value as a **string**. This also
|
||
|
applies to `<input>` elements having any other possible `type` attribute
|
||
|
that's not explicitly covered in different rules above (e.g. `search`,
|
||
|
`email`, `date`, `password`, `hidden`, etc.)
|
||
|
- `<select>` elements without the `multiple` attribute return the value as a
|
||
|
**string** corresponding to the `value` attribute of the selected `option`, or
|
||
|
`undefined` if there's no selected option.
|
||
|
- `<select multiple>` elements return the value as an **array** containing all
|
||
|
the values of the [selected options][].
|
||
|
- `<textarea>` elements return their value as a **string**. The value
|
||
|
corresponds to their node content.
|
||
|
|
||
|
The above rules make it easy, for instance, to switch from using a single select
|
||
|
control to using a group of radio buttons. Or to switch from a multi select
|
||
|
control, to using a group of checkboxes. The resulting set of form values used
|
||
|
by this matcher to compare against would be the same.

#### Examples
|
||
|
|
||
|
```html
|
||
|
<form data-testid="login-form">
|
||
|
<input type="text" name="username" value="jane.doe" />
|
||
|
<input type="password" name="password" value="12345678" />
|
||
|
<input type="checkbox" name="rememberMe" checked />
|
||
|
<button type="submit">Sign in</button>
|
||
|
</form>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('login-form')).toHaveFormValues({
|
||
|
username: 'jane.doe',
|
||
|
rememberMe: true,
|
||
|
})
|
||
|
```
|
||
|
|
||
|
### `toHaveStyle`
|
||
|
|
||
|
```typescript
|
||
|
toHaveStyle(css: string | object)
|
||
|
```
|
||
|
|
||
|
This allows you to check if a certain element has some specific css properties
|
||
|
with specific values applied. It matches only if the element has _all_ the
|
||
|
expected properties applied, not just some of them.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<button
|
||
|
data-testid="delete-button"
|
||
|
style="display: none; background-color: red"
|
||
|
>
|
||
|
Delete item
|
||
|
</button>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const button = getByTestId('delete-button')
|
||
|
|
||
|
expect(button).toHaveStyle('display: none')
|
||
|
expect(button).toHaveStyle({display: 'none'})
|
||
|
expect(button).toHaveStyle(`
|
||
|
background-color: red;
|
||
|
display: none;
|
||
|
`)
|
||
|
expect(button).toHaveStyle({
|
||
|
backgroundColor: 'red',
|
||
|
display: 'none',
|
||
|
})
|
||
|
expect(button).not.toHaveStyle(`
|
||
|
background-color: blue;
|
||
|
display: none;
|
||
|
`)
|
||
|
expect(button).not.toHaveStyle({
|
||
|
backgroundColor: 'blue',
|
||
|
display: 'none',
|
||
|
})
|
||
|
```
|
||
|
|
||
|
This also works with rules that are applied to the element via a class name for
|
||
|
which some rules are defined in a stylesheet currently active in the document.
|
||
|
The usual rules of css precedence apply.
|
||
|
|
||

|
||
|
|
||
|
### `toHaveTextContent`
|
||
|
|
||
|
```typescript
|
||
|
toHaveTextContent(text: string | RegExp, options?: {normalizeWhitespace: boolean})
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given node has a text content or not. This
|
||
|
supports elements, but also text nodes and fragments.
|
||
|
|
||
|
When a `string` argument is passed through, it will perform a partial
|
||
|
case-sensitive match to the node content.
|
||
|
|
||
|
To perform a case-insensitive match, you can use a `RegExp` with the `/i`
|
||
|
modifier.
|
||
|
|
||
|
If you want to match the whole content, you can use a `RegExp` to do it.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<span data-testid="text-content">Text Content</span>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const element = getByTestId('text-content')
|
||
|
|
||
|
expect(element).toHaveTextContent('Content')
|
||
|
expect(element).toHaveTextContent(/^Text Content$/) // to match the whole content
|
||
|
expect(element).toHaveTextContent(/content$/i) // to use case-insensitive match
|
||
|
expect(element).not.toHaveTextContent('content')
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toHaveValue`
|
||
|
|
||
|
```typescript
|
||
|
toHaveValue(value: string | string[] | number)
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given form element has the specified value.
|
||
|
It accepts `<input>`, `<select>` and `<textarea>` elements with the exception of
|
||
|
`<input type="checkbox">` and `<input type="radio">`, which can be meaningfully
|
||
|
matched only using [`toBeChecked`](#tobechecked) or
|
||
|
[`toHaveFormValues`](#tohaveformvalues).
|
||
|
|
||
|
For all other form elements, the value is matched using the same algorithm as in
|
||
|
[`toHaveFormValues`](#tohaveformvalues) does.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<input type="text" value="text" data-testid="input-text" />
|
||
|
<input type="number" value="5" data-testid="input-number" />
|
||
|
<input type="text" data-testid="input-empty" />
|
||
|
<select multiple data-testid="select-number">
|
||
|
<option value="first">First Value</option>
|
||
|
<option value="second" selected>Second Value</option>
|
||
|
<option value="third" selected>Third Value</option>
|
||
|
</select>
|
||
|
```
|
||
|
|
||
|
##### Using DOM Testing Library
|
||
|
|
||
|
```javascript
|
||
|
const textInput = getByTestId('input-text')
|
||
|
const numberInput = getByTestId('input-number')
|
||
|
const emptyInput = getByTestId('input-empty')
|
||

const selectInput = getByTestId('select-number')
|
||
|
|
||
|
expect(textInput).toHaveValue('text')
|
||
|
expect(numberInput).toHaveValue(5)
|
||
|
expect(emptyInput).not.toHaveValue()
|
||
|
expect(selectInput).toHaveValue(['second', 'third'])

### `toHaveDisplayValue`
|
||
|
|
||
|
```typescript
|
||
|
toHaveDisplayValue(value: string | RegExp | (string|RegExp)[])
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given form element has the specified
|
||
|
displayed value (the one the end user will see). It accepts `<input>`,
|
||
|
`<select>` and `<textarea>` elements with the exception of
|
||
|
`<input type="checkbox">` and `<input type="radio">`, which can be meaningfully
|
||
|
matched only using [`toBeChecked`](#tobechecked) or
|
||
|
[`toHaveFormValues`](#tohaveformvalues).
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<label for="input-example">First name</label>
|
||
|
<input type="text" id="input-example" value="Luca" />
|
||
|
|
||
|
<label for="textarea-example">Description</label>
|
||
|
<textarea id="textarea-example">An example description here.</textarea>
|
||
|
|
||
|
<label for="single-select-example">Fruit</label>
|
||
|
<select id="single-select-example">
|
||
|
<option value="">Select a fruit...</option>
|
||
|
<option value="banana">Banana</option>
|
||
|
<option value="ananas">Ananas</option>
|
||
|
<option value="avocado">Avocado</option>
|
||
|
</select>
|
||
|
|
||
|
<label for="multiple-select-example">Fruits</label>
|
||
|
<select id="multiple-select-example" multiple>
|
||
|
<option value="">Select a fruit...</option>
|
||
|
<option value="banana" selected>Banana</option>
|
||
|
<option value="ananas">Ananas</option>
|
||
|
<option value="avocado" selected>Avocado</option>
|
||
|
</select>
|
||
|
```
|
||
|
|
||
|
##### Using DOM Testing Library
|
||
|
|
||
|
```javascript
|
||
|
const input = screen.getByLabelText('First name')
|
||
|
const textarea = screen.getByLabelText('Description')
|
||
|
const selectSingle = screen.getByLabelText('Fruit')
|
||
|
const selectMultiple = screen.getByLabelText('Fruits')
|
||
|
|
||
|
expect(input).toHaveDisplayValue('Luca')
|
||
|
expect(input).toHaveDisplayValue(/Luc/)
|
||
|
expect(textarea).toHaveDisplayValue('An example description here.')
|
||
|
expect(textarea).toHaveDisplayValue(/example/)
|
||
|
expect(selectSingle).toHaveDisplayValue('Select a fruit...')
|
||
|
expect(selectSingle).toHaveDisplayValue(/Select/)
|
||

expect(selectMultiple).toHaveDisplayValue([/Avocado/, 'Banana'])
|
||
|
```

|
### `toBeChecked`
|
||
|
|
||
|
```typescript
|
||
|
toBeChecked()
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given element is checked. It accepts an
|
||
|
`input` of type `checkbox` or `radio` and elements with a `role` of `checkbox`,
|
||
|
`radio` or `switch` with a valid `aria-checked` attribute of `"true"` or
|
||
|
`"false"`.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<input type="checkbox" checked data-testid="input-checkbox-checked" />
|
||
|
<input type="checkbox" data-testid="input-checkbox-unchecked" />
|
||
|
<div role="checkbox" aria-checked="true" data-testid="aria-checkbox-checked" />
|
||
|
<div
|
||
|
role="checkbox"
|
||
|
aria-checked="false"
|
||
|
data-testid="aria-checkbox-unchecked"
|
||
|
/>
|
||
|
|
||
|
<input type="radio" checked value="foo" data-testid="input-radio-checked" />
|
||
|
<input type="radio" value="foo" data-testid="input-radio-unchecked" />
|
||
|
<div role="radio" aria-checked="true" data-testid="aria-radio-checked" />
|
||
|
<div role="radio" aria-checked="false" data-testid="aria-radio-unchecked" />
|
||
|
<div role="switch" aria-checked="true" data-testid="aria-switch-checked" />
|
||
|
<div role="switch" aria-checked="false" data-testid="aria-switch-unchecked" />
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const inputCheckboxChecked = getByTestId('input-checkbox-checked')
|
||
|
const inputCheckboxUnchecked = getByTestId('input-checkbox-unchecked')
|
||
|
const ariaCheckboxChecked = getByTestId('aria-checkbox-checked')
|
||
|
const ariaCheckboxUnchecked = getByTestId('aria-checkbox-unchecked')
|
||
|
expect(inputCheckboxChecked).toBeChecked()
|
||
|
expect(inputCheckboxUnchecked).not.toBeChecked()
|
||
|
expect(ariaCheckboxChecked).toBeChecked()
|
||
|
expect(ariaCheckboxUnchecked).not.toBeChecked()
|
||
|
|
||
|
const inputRadioChecked = getByTestId('input-radio-checked')
|
||
|
const inputRadioUnchecked = getByTestId('input-radio-unchecked')
|
||
|
const ariaRadioChecked = getByTestId('aria-radio-checked')
|
||
|
const ariaRadioUnchecked = getByTestId('aria-radio-unchecked')
|
||
|
expect(inputRadioChecked).toBeChecked()
|
||
|
expect(inputRadioUnchecked).not.toBeChecked()
|
||
|
expect(ariaRadioChecked).toBeChecked()
|
||
|
expect(ariaRadioUnchecked).not.toBeChecked()
|
||
|
|
||
|
const ariaSwitchChecked = getByTestId('aria-switch-checked')
|
||
|
const ariaSwitchUnchecked = getByTestId('aria-switch-unchecked')
|
||
|
expect(ariaSwitchChecked).toBeChecked()
|
||
|
expect(ariaSwitchUnchecked).not.toBeChecked()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBePartiallyChecked`
|
||
|
|
||
|
```typescript
|
||
|
toBePartiallyChecked()
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given element is partially checked. It
|
||
|
accepts an `input` of type `checkbox` and elements with a `role` of `checkbox`
|
||
|
with a `aria-checked="mixed"`, or `input` of type `checkbox` with
|
||
|
`indeterminate` set to `true`
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<input type="checkbox" aria-checked="mixed" data-testid="aria-checkbox-mixed" />
|
||
|
<input type="checkbox" checked data-testid="input-checkbox-checked" />
|
||
|
<input type="checkbox" data-testid="input-checkbox-unchecked" />
|
||
|
<div role="checkbox" aria-checked="true" data-testid="aria-checkbox-checked" />
|
||
|
<div
|
||
|
role="checkbox"
|
||
|
aria-checked="false"
|
||
|
data-testid="aria-checkbox-unchecked"
|
||
|
/>
|
||
|
<input type="checkbox" data-testid="input-checkbox-indeterminate" />
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const ariaCheckboxMixed = getByTestId('aria-checkbox-mixed')
|
||
|
const inputCheckboxChecked = getByTestId('input-checkbox-checked')
|
||
|
const inputCheckboxUnchecked = getByTestId('input-checkbox-unchecked')
|
||
|
const ariaCheckboxChecked = getByTestId('aria-checkbox-checked')
|
||
|
const ariaCheckboxUnchecked = getByTestId('aria-checkbox-unchecked')
|
||
|
const inputCheckboxIndeterminate = getByTestId('input-checkbox-indeterminate')
|
||
|
|
||
|
expect(ariaCheckboxMixed).toBePartiallyChecked()
|
||
|
expect(inputCheckboxChecked).not.toBePartiallyChecked()
|
||
|
expect(inputCheckboxUnchecked).not.toBePartiallyChecked()
|
||
|
expect(ariaCheckboxChecked).not.toBePartiallyChecked()
|
||
|
expect(ariaCheckboxUnchecked).not.toBePartiallyChecked()
|
||
|
|
||
|
inputCheckboxIndeterminate.indeterminate = true
|
||
|
expect(inputCheckboxIndeterminate).toBePartiallyChecked()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toHaveErrorMessage`
|
||
|
|
||
|
```typescript
|
||
|
toHaveErrorMessage(text: string | RegExp)
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given element has an
|
||
|
[ARIA error message](https://www.w3.org/TR/wai-aria/#aria-errormessage) or not.
|
||
|
|
||
|
Use the `aria-errormessage` attribute to reference another element that contains
|
||
|
custom error message text. Multiple ids is **NOT** allowed. Authors MUST use
|
||
|
`aria-invalid` in conjunction with `aria-errormessage`. Learn more from
|
||
|
[`aria-errormessage` spec](https://www.w3.org/TR/wai-aria/#aria-errormessage).
|
||
|
|
||
|
Whitespace is normalized.
|
||
|
|
||
|
When a `string` argument is passed through, it will perform a whole
|
||
|
case-sensitive match to the error message text.
|
||
|
|
||
|
To perform a case-insensitive match, you can use a `RegExp` with the `/i`
|
||
|
modifier.
|
||
|
|
||
|
To perform a partial match, you can pass a `RegExp` or use
|
||
|
`expect.stringContaining("partial string")`.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<label for="startTime"> Please enter a start time for the meeting: </label>
|
||
|
<input
|
||
|
id="startTime"
|
||
|
type="text"
|
||
|
aria-errormessage="msgID"
|
||
|
aria-invalid="true"
|
||
|
value="11:30 PM"
|
||
|
/>
|
||
|
<span id="msgID" aria-live="assertive" style="visibility:visible">
|
||
|
Invalid time: the time must be between 9:00 AM and 5:00 PM
|
||
|
</span>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const timeInput = getByLabel('startTime')
|
||
|
|
||
|
expect(timeInput).toHaveErrorMessage(
|
||
|
'Invalid time: the time must be between 9:00 AM and 5:00 PM',
|
||
|
)
|
||
|
expect(timeInput).toHaveErrorMessage(/invalid time/i) // to partially match
|
||
|
expect(timeInput).toHaveErrorMessage(expect.stringContaining('Invalid time')) // to partially match
|
||
|
expect(timeInput).not.toHaveErrorMessage('Pikachu!')
|
||
|
```
|
||
|
|
||
|
## Deprecated matchers
|
||
|
|
||
|
### `toBeEmpty`
|
||
|
|
||
|
> Note: This matcher is being deprecated due to a name clash with
|
||
|
> `jest-extended`. See more info in #216. In the future, please use only
|
||
|
> [`toBeEmptyDOMElement`](#toBeEmptyDOMElement)
|
||
|
|
||
|
```typescript
|
||
|
toBeEmpty()
|
||
|
```
|
||
|
|
||
|
This allows you to assert whether an element has content or not.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<span data-testid="not-empty"><span data-testid="empty"></span></span>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
expect(getByTestId('empty')).toBeEmpty()
|
||
|
expect(getByTestId('not-empty')).not.toBeEmpty()
|
||
|
```
|
||
|
|
||
|
<hr />
|
||
|
|
||
|
### `toBeInTheDOM`
|
||
|
|
||
|
> This custom matcher is deprecated. Prefer
|
||
|
> [`toBeInTheDocument`](#tobeinthedocument) instead.
|
||
|
|
||
|
```typescript
|
||
|
toBeInTheDOM()
|
||
|
```
|
||
|
|
||
|
This allows you to check whether a value is a DOM element, or not.
|
||
|
|
||
|
Contrary to what its name implies, this matcher only checks that you passed to
|
||
|
it a valid DOM element. It does not have a clear definition of what "the DOM"
|
||
|
is. Therefore, it does not check whether that element is contained anywhere.
|
||
|
|
||
|
This is the main reason why this matcher is deprecated, and will be removed in
|
||
|
the next major release. You can follow the discussion around this decision in
|
||
|
more detail [here](https://github.com/testing-library/jest-dom/issues/34).
|
||
|
|
||
|
As an alternative, you can use [`toBeInTheDocument`](#tobeinthedocument) or
|
||
|
[`toContainElement`](#tocontainelement). Or if you just want to check if a value
|
||
|
is indeed an `HTMLElement` you can always use some of
|
||
|
[jest's built-in matchers](https://jestjs.io/docs/en/expect#tobeinstanceofclass):
|
||
|
|
||
|
```js
|
||
|
expect(document.querySelector('.ok-button')).toBeInstanceOf(HTMLElement)
|
||
|
expect(document.querySelector('.cancel-button')).toBeTruthy()
|
||
|
```
|
||
|
|
||
|
> Note: The differences between `toBeInTheDOM` and `toBeInTheDocument` are
|
||
|
> significant. Replacing all uses of `toBeInTheDOM` with `toBeInTheDocument`
|
||
|
> will likely cause unintended consequences in your tests. Please make sure when
|
||
|
> replacing `toBeInTheDOM` to read through the documentation of the proposed
|
||
|
> alternatives to see which use case works better for your needs.
|
||
|
|
||
|
### `toHaveDescription`
|
||
|
|
||
|
> This custom matcher is deprecated. Prefer
|
||
|
> [`toHaveAccessibleDescription`](#tohaveaccessibledescription) instead, which
|
||
|
> is more comprehensive in implementing the official spec.
|
||
|
|
||
|
```typescript
|
||
|
toHaveDescription(text: string | RegExp)
|
||
|
```
|
||
|
|
||
|
This allows you to check whether the given element has a description or not.
|
||
|
|
||
|
An element gets its description via the
|
||
|
[`aria-describedby` attribute](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_aria-describedby_attribute).
|
||
|
Set this to the `id` of one or more other elements. These elements may be nested
|
||
|
inside, be outside, or a sibling of the passed in element.
|
||
|
|
||
|
Whitespace is normalized. Using multiple ids will
|
||
|
[join the referenced elements’ text content separated by a space](https://www.w3.org/TR/accname-1.1/#mapping_additional_nd_description).
|
||
|
|
||
|
When a `string` argument is passed through, it will perform a whole
|
||
|
case-sensitive match to the description text.
|
||
|
|
||
|
To perform a case-insensitive match, you can use a `RegExp` with the `/i`
|
||
|
modifier.
|
||
|
|
||
|
To perform a partial match, you can pass a `RegExp` or use
|
||
|
`expect.stringContaining("partial string")`.
|
||
|
|
||
|
#### Examples
|
||
|
|
||
|
```html
|
||
|
<button aria-label="Close" aria-describedby="description-close">X</button>
|
||
|
<div id="description-close">Closing will discard any changes</div>
|
||
|
|
||
|
<button>Delete</button>
|
||
|
```
|
||
|
|
||
|
```javascript
|
||
|
const closeButton = getByRole('button', {name: 'Close'})
|
||
|
|
||
|
expect(closeButton).toHaveDescription('Closing will discard any changes')
|
||
|
expect(closeButton).toHaveDescription(/will discard/) // to partially match
|
||
|
expect(closeButton).toHaveDescription(expect.stringContaining('will discard')) // to partially match
|
||
|
expect(closeButton).toHaveDescription(/^closing/i) // to use case-insensitive match
|
||
|
expect(closeButton).not.toHaveDescription('Other description')
|
||
|
|
||
|
const deleteButton = getByRole('button', {name: 'Delete'})
|
||
|
expect(deleteButton).not.toHaveDescription()
|
||
|
expect(deleteButton).toHaveDescription('') // Missing or empty description always becomes a blank string
|
||
|
```
|
||
|
|
||
|
## Inspiration
|
||
|
|
||
|
This whole library was extracted out of Kent C. Dodds' [DOM Testing
|
||
|
Library][dom-testing-library], which was in turn extracted out of [React Testing
|
||
|
Library][react-testing-library].
|
||
|
|
||
|
The intention is to make this available to be used independently of these other
|
||
|
libraries, and also to make it more clear that these other libraries are
|
||
|
independent from jest, and can be used with other tests runners as well.
|
||
|
|
||
|
## Other Solutions
|
||
|
|
||
|
I'm not aware of any, if you are please [make a pull request][prs] and add it
|
||
|
here!
|
||
|
|
||
|
If you would like to further test the accessibility and validity of the DOM
|
||
|
consider [`jest-axe`](https://github.com/nickcolley/jest-axe). It doesn't
|
||
|
overlap with `jest-dom` but can complement it for more in-depth accessibility
|
||
|
checking (eg: validating `aria` attributes or ensuring unique id attributes).
|
||
|
|
||
|
## Guiding Principles
|
||
|
|
||
|
> [The more your tests resemble the way your software is used, the more
|
||
|
> confidence they can give you.][guiding-principle]
|
||
|
|
||
|
This library follows the same guiding principles as its mother library [DOM
|
||
|
Testing Library][dom-testing-library]. Go [check them out][guiding-principle]
|
||
|
for more details.
|
||
|
|
||
|
Additionally, with respect to custom DOM matchers, this library aims to maintain
|
||
|
a minimal but useful set of them, while avoiding bloating itself with merely
|
||
|
convenient ones that can be easily achieved with other APIs. In general, the
|
||
|
overall criteria for what is considered a useful custom matcher to add to this
|
||
|
library, is that doing the equivalent assertion on our own makes the test code
|
||
|
more verbose, less clear in its intent, and/or harder to read.
