playwright-testing-library

playwright + @testing-library/dom = 💖

All your favorite user-centric querying functions from @testing-library/react & @testing-library/library available from Playwright!

⚠�? Note: this is a fork of pptr-testing-library modified to accomodate for some subtle API differences.

Install

npm install --save-dev playwright-testing-library

Use

const {webkit} = require('playwright') // or 'firefox' or 'chromium'
const {getDocument, queries, waitFor} = require('playwright-testing-library')

const {getByTestId, getByLabelText} = queries

const browser = await webkit.launch()
const page = await browser.newPage()

// Grab ElementHandle for document
const $document = await getDocument(page)
// Your favorite query methods are available
const $form = await getByTestId($document, 'my-form')
// returned elements are ElementHandles too!
const $email = await getByLabelText($form, 'Email')
// interact with playwright like usual
await $email.type('[email protected]')
// waiting works too!
await waitFor(() => getByText($document, 'Loading...'))

A little too un-playwright for you? We've got prototype-mucking covered too :)

const {webkit} = require('playwright') // or 'firefox' or 'chromium'
require('playwright-testing-library/extend')

const browser = await webkit.launch()
const page = await browser.newPage()

// getDocument is added to prototype of Page
const $document = await page.getDocument()
// query methods are added directly to prototype of ElementHandle
const $form = await $document.getByTestId('my-form')
// destructing works if you explicitly call getQueriesForElement
const {getByText} = $form.getQueriesForElement()
// ...

API

Unique methods, not part of @testing-library/dom

• getDocument(page: playwright.Page): ElementHandle - get an ElementHandle for the document
• wait(conditionFn: () => {}): Promise<{}> - wait for the condition to not throw (wrapper around waitForExpect)

@testing-library/dom API. All get*/query* methods are supported.

• getQueriesForElement(handle: ElementHandle): ElementHandle & QueryUtils - extend the input object with the query API and return it
• getNodeText(handle: ElementHandle): Promise<string> - get the text content of the element
• queries: QueryUtils - the query subset of @testing-library/dom exports
  • queryByPlaceholderText
  • queryAllByPlaceholderText
  • getByPlaceholderText
  • getAllByPlaceholderText
  • findByPlaceholderText
  • findAllByPlaceholderText
  • queryByText
  • queryAllByText
  • getByText
  • getAllByText
  • findByText
  • findAllByText
  • queryByLabelText
  • queryAllByLabelText
  • getByLabelText

  • queryByAltText

  • findAllByAltText
  • queryByTestId
  • queryAllByTestId
  • getByTestId

Known Limitations

• Async utilities waitForElement, waitForElementToBeRemoved and waitForDomChange are not exposed. Consider using a find* query.
• fireEvent method is not exposed, use Playwright's built-ins instead.
• expect assertion extensions are not available.

Special Thanks

• pptr-testing-library
• @testing-library/dom of course!
