Async

See Async API. Remember to await or .then() the result of async functions in your tests!

  • waitFor (Promise) retry the function within until it stops throwing or times out
  • waitForElementToBeRemoved (Promise) retry the function until it no longer returns a DOM node

Deprecated since v7.0.0:

  • wait (Promise) retry the function within until it stops throwing or times
  • waitForElement (Promise) retry the function until it returns an element or an array of elements
  • findBy and findAllBy queries are async and retry until either a timeout or if the query returns successfully; they wrap waitForElement
  • waitForDomChange (Promise) retry the function each time the DOM is changed

Events

See Considerations for fireEvent, Events API

  • fireEvent trigger DOM event: fireEvent(node, event)
  • fireEvent.* helpers for default event types

Other

See Helpers API, Config API

  • within take a node and return an object with all the queries bound to the node (used to return the queries from React Testing Library's render method): within(node).getByText("hello")
  • configure change global options: configure({testIdAttribute: 'my-data-test-id'})

Text Match Options

Given the following HTML:

<div>Hello World</div>

Will find the div:

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

Given a button that updates the page after some time:

test('loads items eventually', async () => {
// Click button
fireEvent.click(getByText(node, 'Load'))
// Wait for page to update with query text
const items = await findByText(node, /Item #[0-9]: /)
expect(items).toHaveLength(10)
})
