About Queries


Queries are the methods that Testing Library gives you to find elements on the page. There are several types of queries ("get", "find", "query"); the difference between them is whether the query will throw an error if no element is found or if it will return a Promise and retry. Depending on what page content you are selecting, different queries may be more or less appropriate. See the priority guide for recommendations on how to make use of semantic queries to test your page in the most accessible way.

After selecting an element, you can use the Events API or user-event to fire events and simulate user interactions with the page, or use Jest and jest-dom to make assertions about the element.

There are Testing Library helper methods that work with queries. As elements appear and disappear in response to actions, Async APIs like waitFor or findBy queries can be used to await the changes in the DOM. To find only elements that are children of a specific element, you can use within. If necessary, there are also a few options you can configure, like the timeout for retries and the default testID attribute.


import { screen } from '@testing-library/react' // (or /dom, /vue, ...)
test('should show login form', () => {
render(<Login />)
const input = screen.getByLabelText('Username')
// Events and assertions...

Types of Queries

  • Single Elements
    • getBy...: Returns the matching node for a query, and throw a descriptive error if no elements match or if more than one match is found (use getAllBy instead if more than one element is expected).
    • queryBy...: Returns the first matching node for a query, and return null if no elements match. This is useful for asserting an element that is not present. Throws an error if more than one match is found (use queryAllBy instead if this is OK).
    • findBy...: Returns a Promise which resolves when an element is found which matches the given query. The promise is rejected if no element is found or if more than one element is found after a default timeout of 1000ms. If you need to find more than one element, use findAllBy.
  • Multiple Elements
    • getAllBy...: Returns an array of all matching nodes for a query, and throws an error if no elements match.
    • queryAllBy...: Returns an array of all matching nodes for a query, and return an empty array ([]) if no elements match.
    • findAllBy...: Returns a promise which resolves to an array of elements when any elements are found which match the given query. The promise is rejected if no elements are found after a default timeout of 1000ms.
      • findBy methods are a combination of getBy* queries and waitFor. They accept the waitFor options as the last argument (i.e. await screen.findByText('text', queryOptions, waitForOptions))

Based on the Guiding Principles, your test should resemble how users interact with your code (component, page, etc.) as much as possible. With this in mind, we recommend this order of priority:

  1. Queries Accessible to Everyone queries that reflect the experience of visual/mouse users as well as those that use assistive technology
    1. getByRole: This can be used to query every element that is exposed in the accessibility tree. With the name option you can filter the returned elements by their accessible name. This should be your top preference for just about everything. There's not much you can't get with this (if you can't, it's possible your UI is inaccessible). Most often, this will be used with the name option like so: getByRole('button', {name: /submit/i}). Check the list of roles.
    2. getByLabelText: Only really good for form fields, but this is the number one method a user finds those elements, so it should be your top preference.
    3. getByPlaceholderText: A placeholder is not a substitute for a label. But if that's all you have, then it's better than alternatives.
    4. getByText: Not useful for forms, but this is the number 1 method a user finds most non-interactive elements (like divs and spans).
    5. getByDisplayValue: The current value of a form element can be useful when navigating a page with filled-in values.
  2. Semantic Queries HTML5 and ARIA compliant selectors. Note that the user experience of interacting with these attributes varies greatly across browsers and assistive technology.
    1. getByAltText: If your element is one which supports alt text (img, area, and input), then you can use this to find that element.
    2. getByTitle: The title attribute is not consistently read by screenreaders, and is not visible by default for sighted users
  3. Test IDs
    1. getByTestId: The user cannot see (or hear) these, so this is only recommended for cases where you can't match by role or text or it doesn't make sense (e.g. the text is dynamic).

Using Queries

The base queries from DOM Testing Library require you to pass a container as the first argument. Most framework-implementations of Testing Library provide a pre-bound version of these queries when you render your components with them which means you do not have to provide a container. In addition, if you just want to query document.body then you can use the screen export as demonstrated below (using screen is recommended).

The primary argument to a query can be a string, regular expression, or function. There are also options to adjust how node text is parsed. See TextMatch for documentation on what can be passed to a query.

Given the following DOM elements (which can be rendered by React, Vue, Angular, or plain HTML code):

<div id="app">
<label for="username-input">Username</label>
<input id="username-input" />

You can use a query to find an element (byLabelText, in this case):

import { screen, getByLabelText } from '@testing-library/dom'
// With screen:
const inputNode1 = screen.getByLabelText('Username')
// Without screen, you need to provide a container:
const container = document.querySelector('#app')
const inputNode2 = getByLabelText(container, 'Username')


All of the queries exported by DOM Testing Library accept a container as the first argument. Because querying the entire document.body is very common, DOM Testing Library also exports a screen object which has every query that is pre-bound to document.body (using the within functionality). Wrappers such as React Testing Library re-export screen so you can use it the same way.

Here's how you use it:

import { screen } from '@testing-library/dom'
document.body.innerHTML = `
<label for="example">Example</label>
<input id="example" />
const exampleInput = screen.getByLabelText('Example')


You need a global DOM environment to use screen. If you're using jest, with the testEnvironment set to jsdom, a global DOM environment will be available for you.

If you're loading your test with a script tag, make sure it comes after the body. An example can be seen here.


Most of the query APIs take a TextMatch as an argument, which means the argument can be either a string, regex, or a function which returns true for a match and false for a mismatch.

TextMatch Examples

Given the following HTML:

<div>Hello World</div>

Will find the div:

// Matching a string:
screen.getByText('Hello World') // full string match
screen.getByText('llo Worl', { exact: false }) // substring match
screen.getByText('hello world', { exact: false }) // ignore case
// Matching a regex:
screen.getByText(/World/) // substring match
screen.getByText(/world/i) // substring match, ignore case
screen.getByText(/^hello world$/i) // full string match, ignore case
screen.getByText(/Hello W?oRlD/i) // advanced regex
// Matching with a custom function:
screen.getByText((content, element) => content.startsWith('Hello'))

Will not find the div:

// full string does not match
screen.getByText('Goodbye World')
// case-sensitive regex with different case
screen.getByText(/hello world/)
// function looking for a span when it's actually a div:
screen.getByText((content, element) => {
return element.tagName.toLowerCase() === 'span' && content.startsWith('Hello')


Queries that take a TextMatch also accept an object as the final argument that can contain options that affect the precision of string matching:

  • exact: Defaults to true; matches full strings, case-sensitive. When false, matches substrings and is not case-sensitive.
    • exact has no effect on regex or function arguments.
    • In most cases using a regex instead of a string gives you more control over fuzzy matching and should be preferred over { exact: false }.
  • normalizer: An optional function which overrides normalization behavior. See Normalization.


Before running any matching logic against text in the DOM, DOM Testing Library automatically normalizes that text. By default, normalization consists of trimming whitespace from the start and end of text, and collapsing multiple adjacent whitespace characters into a single space.

If you want to prevent that normalization, or provide alternative normalization (e.g. to remove Unicode control characters), you can provide a normalizer function in the options object. This function will be given a string and is expected to return a normalized version of that string.


Specifying a value for normalizer replaces the built-in normalization, but you can call getDefaultNormalizer to obtain a built-in normalizer, either to adjust that normalization or to call it from your own normalizer.

getDefaultNormalizer takes an options object which allows the selection of behaviour:

  • trim: Defaults to true. Trims leading and trailing whitespace
  • collapseWhitespace: Defaults to true. Collapses inner whitespace (newlines, tabs, repeated spaces) into a single space.

Normalization Examples

To perform a match against text without trimming:

screen.getByText('text', {
normalizer: getDefaultNormalizer({ trim: false }),

To override normalization to remove some Unicode characters whilst keeping some (but not all) of the built-in normalization behavior:

screen.getByText('text', {
normalizer: (str) =>
getDefaultNormalizer({ trim: false })(str).replace(/[\u200E-\u200F]*/g, ''),



For convenience screen also exposes a debug method in addition to the queries. This method is essentially a shortcut for console.log(prettyDOM()). It supports debugging the document, a single element, or an array of elements.

import { screen } from '@testing-library/dom'
document.body.innerHTML = `
// debug document
// debug single element
// debug multiple elements


For debugging using testing-playground, screen exposes this convenient method which logs a URL that can be opened in a browser.

import { screen } from '@testing-library/dom'
document.body.innerHTML = `
// log entire document to testing-playground
// log a single element

Manual Queries

On top of the queries provided by the testing library, you can use the regular querySelector DOM API to query elements. Note that using this as an escape hatch to query by class or id is not recommended because they are invisible to the user. Use a testid if you have to, to make your intention to fall back to non-semantic queries clear and establish a stable API contract in the HTML.

// @testing-library/react
const { container } = render(<MyComponent />)
const foo = container.querySelector('[data-foo="bar"]')

Chrome extension

Do you still have problems knowing how to use Testing Library queries?

There is a very cool Chrome extension named Testing Playground, and it helps you find the best queries to select elements. It allows you to inspect the element hierarchies in the Chrome Developer Tools, and provides you with suggestions on how to select them, while encouraging good testing practices.


If you want to get more familiar with these queries, you can try them out on testing-playground.com. Testing Playground is an interactive sandbox where you can run different queries against your own html, and get visual feedback matching the rules mentioned above.
