playwright-testing-library

🔍 Find elements in playwright like your users with queries from @testing-library/dom

✨ Features

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

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

• Standalone queries — playwright-testing-library or...
• Playwright extensions — playwright-testing-library/extend
• Asynchronous assertion helper (via wait-for-expect)

🌱 Getting Started

1. Install

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

or

yarn add --dev playwright-testing-library

2a. Use standalone queries

const {webkit} = require('playwright') // or 'firefox' or 'chromium'
const {getDocument, queries} = 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('playwright@example.com')

// ...

2b. Use extensions

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

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

// Grab document with `getDocument`, which is added to the prototype of `Paqe`
const $document = await page.getDocument()

// Query methods are added directly to prototype of `ElementHandle`
const $form = await $document.getByTestId('my-form')

// Scope queries with `getQueriesForElement`
const {getByLabelText} = $form.getQueriesForElement()

const $email = await getByLabelText('Email')

// Interact with Playwright like usual
await $email.type('playwright@example.com')

// ...

🔌 API

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

• Get an ElementHandle for the document

  getDocument(page: playwright.Page): ElementHandle

• Wait for an assertion (wrapper around wait-for-expect)

  waitFor(
    expectation: () => void | Promise<void>,
    timeout?: number,
    interval?: number
  ): Promise<{}>

---

The @testing-library/dom — All get* and 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

  • queryByAltText
  • queryAllByAltText
  • getByAltText
  • getAllByAltText
  • findByAltText
  • findAllByAltText
  • queryByTestId
  • queryAllByTestId
  • getByTestId
  • getAllByTestId
  • findByTestId
  • findAllByTestId
  • queryByTitle

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
