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. ## Table of Contents <!-- START doctoc generated TOC please keep comment here to allow auto update --> <!-- DON'T EDIT THIS SECTION, INSTEAD RE-RUN doctoc TO UPDATE --> - [Installation](#installation) - [Usage](#usage) - [With TypeScript](#with-typescript) - [Custom matchers](#custom-matchers) - [`toBeDisabled`](#tobedisabled) - [`toBeEnabled`](#tobeenabled) - [`toBeEmptyDOMElement`](#tobeemptydomelement) - [`toBeInTheDocument`](#tobeinthedocument) - [`toBeInvalid`](#tobeinvalid) - [`toBeRequired`](#toberequired) - [`toBeValid`](#tobevalid) - [`toBeVisible`](#tobevisible) - [`toContainElement`](#tocontainelement) - [`toContainHTML`](#tocontainhtml) - [`toHaveAccessibleDescription`](#tohaveaccessibledescription) - [`toHaveAccessibleName`](#tohaveaccessiblename) - [`toHaveAttribute`](#tohaveattribute) - [`toHaveClass`](#tohaveclass) - [`toHaveFocus`](#tohavefocus) - [`toHaveFormValues`](#tohaveformvalues) - [`toHaveStyle`](#tohavestyle) - [`toHaveTextContent`](#tohavetextcontent) - [`toHaveValue`](#tohavevalue) - [`toHaveDisplayValue`](#tohavedisplayvalue) - [`toBeChecked`](#tobechecked) - [`toBePartiallyChecked`](#tobepartiallychecked) - [`toHaveErrorMessage`](#tohaveerrormessage) - [Deprecated matchers](#deprecated-matchers) - [`toBeEmpty`](#tobeempty) - [`toBeInTheDOM`](#tobeinthedom) - [`toHaveDescription`](#tohavedescription) - [Inspiration](#inspiration) - [Other Solutions](#other-solutions) - [Guiding Principles](#guiding-principles) - [Contributors](#contributors) - [LICENSE](#license) <!-- END doctoc generated TOC please keep comment here to allow auto update --> ## 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() ``` <hr /> ### `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>') ``` > Chances are you probably do not need to use this matcher. We encourage testing > from the perspective of how the user perceives the app in a browser. That's > why testing against a specific DOM structure is not advised. > > It could be useful in situations where the code being tested renders html that > was obtained from an external source, and you want to validate that that html > code was used as intended. > > It should not be used to check DOM structure that you control. Please use > [`toContainElement`](#tocontainelement) instead. <hr /> ### `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. [selected options]: https://developer.mozilla.org/en-US/docs/Web/API/HTMLSelectElement/selectedOptions [form]: https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement [fieldset]: https://developer.mozilla.org/en-US/docs/Web/API/HTMLFieldSetElement [.elements]: https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/elements #### 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. <hr /> ### `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']) ``` <hr /> ### `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']) ``` <hr /> ### `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 elementsβ 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. ## Contributors Thanks goes to these people ([emoji key][emojis]): <!-- ALL-CONTRIBUTORS-LIST:START - Do not remove or modify this section --> <!-- prettier-ignore-start --> <!-- markdownlint-disable --> <table> <tr> <td align="center"><a href="https://kentcdodds.com"><img src="https://avatars.githubusercontent.com/u/1500684?v=3?s=100" width="100px;" alt=""/><br /><sub><b>Kent C.
