Playwright Testing With Playwright Test Runner

Playwright Test Runner is used for end-to-end automated testing of websites and web apps across all major browsers. You can run parallel tests, get context isolation out of the box, capture videos, screenshots, and other test artifacts on test failure, and use fixtures with Playwright test runner.

LambdaTest enables you to run Playwright tests with the Playwright test runner across 40+ real browser and operating system combinations. This guide will outline the fundamentals of getting started with Playwright testing on the LambdaTest platform using the Playwright test runner.

Prerequisites​

Note: All the code samples in this documentation can be found in the LambdaTest's Repository on GitHub. You can either download or clone the repository to quickly run your tests.

Running Playwright Tests With Playwright Test Runner​

In your playwright.config.js file, add the browserName, browserVersion, and platform in the below projects configuration.

const { devices } = require('@playwright/test')
// Playwright config to run tests on LambdaTest platform and local
const config = {
testDir: 'tests',
testMatch: '**/*.spec.js',
timeout: 60000,
projects: [
// -- LambdaTest Config --
  // name in the format: browserName:browserVersion:platform@lambdatest
  // Browsers allowed: `Chrome`, `MicrosoftEdge`, `pw-chromium`, `pw-firefox` and `pw-webkit`
  // Use additional configuration options provided by Playwright if required: https://playwright.dev/docs/api/class-testconfig
    {
      name: 'chrome:latest:MacOS Catalina@lambdatest',
      use: {
        viewport: { width: 1920, height: 1080 }
      }
    },
    {
      name: 'MicrosoftEdge:90:Windows 10@lambdatest',
      use: {
        ...devices['iPhone 12 Pro Max']
      }
    },
  ]
}

module.exports = config

Pass the below command to run the test.

npm run test

Testing With Playwright Test When Migrating To LambdaTest​

If you are migrating test suites to LambdaTest, then follow the below steps.

  1. Add the lambdatest-setup.js to your project route.

  2. Include the playwright.config.js in your project in the below format.

const { devices } = require('@playwright/test')

// Playwright config to run tests on LambdaTest platform and local
const config = {
  testDir: 'tests',
  testMatch: '**/*.spec.js',
  timeout: 60000,
  use: {
    viewport: null
  },
  projects: [
    // -- LambdaTest Config --
    // name in the format: browserName:browserVersion:platform@lambdatest
    // Browsers allowed: `Chrome`, `MicrosoftEdge`, `pw-chromium`, `pw-firefox` and `pw-webkit`
    // Use additional configuration options provided by Playwright if required: https://playwright.dev/docs/api/class-testconfig
    {
      name: 'chrome:latest:MacOS Catalina@lambdatest',
      use: {
        viewport: { width: 1920, height: 1080 }
      }
    },
    {
      name: 'chrome:latest:Windows 10@lambdatest',
      use: {
        viewport: { width: 1280, height: 720 }
      }
    },
    {
      name: 'MicrosoftEdge:90:Windows 10@lambdatest',
      use: {
        ...devices['iPhone 12 Pro Max']
      }
    },
    {
      name: 'pw-firefox:latest:Windows 10@lambdatest',
      use: {
        viewport: { width: 1280, height: 720 }
      }
    },
    {
      name: 'pw-webkit:latest:Windows 10@lambdatest',
      use: {
        viewport: { width: 1920, height: 1080 }
      }
    }

  ]
}

  1. Add your test script path in playwright.config.js.

  2. Import the test object from lambdatest-setup.js and run your tests.

const { test } = require('../lambdatest-setup')
const { expect } = require('@playwright/test')

test.describe('Browse LambdaTest in different search engines', () => {
  test('Search LambdaTest on Bing', async ({ page }) => {
    await page.goto('https://www.bing.com')
    const element = await page.$('[aria-label="Enter your search term"]')
    await element.click()
    await element.type('LambdaTest')
    await element.press('Enter')
    const title = await page.title()

    console.log('Page title:: ', title)
    // Use the expect API for assertions provided by playwright
    expect(title).toEqual(expect.stringContaining('LambdaTest'))
  })
})
