Parallel Testing With Playwright

TestMu AI allows you to perform parallel testing with Playwright across real browsers and OS to automate your several test cases simultaneously. You can run one test case across various browsers, or you can run multiple test case scenarios in the same browser with different browser versions.

Shown below are the steps on running parallel tests with Playwright on the TestMu AI platform.

Clone the TestMu AI-Playwright GitHub repository and switch to the cloned directory.

git clone https://github.com/LambdaTest/playwright-sample.git
cd playwright-sample-main

Ensure you have npm dependencies installed.
Configure your TestMu AI authentication credentials.

Once you are done with the above-mentioned steps, you can run your parallel tests with Playwright on TestMu AI.

The below test script searches the term 'TestMu AI' on Bing.

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

const parallelTests = async (capability) => {
  console.log('Initialising test:: ', capability['LT:Options']['name'])

  const browser = await chromium.connect({
    wsEndpoint: `wss://cdp.lambdatest.com/playwright?capabilities=${encodeURIComponent(JSON.stringify(capability))}`
  })

  const page = await browser.newPage()

  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()

  try {
    expect(title).toEqual('LambdaTest - Search')
    // Mark the test as completed or failed
    await page.evaluate(_ => {}, `lambdatest_action: ${JSON.stringify({ action: 'setTestStatus', arguments: { status: 'passed', remark: 'Title matched' } })}`)
  } catch {
    await page.evaluate(_ => {}, `lambdatest_action: ${JSON.stringify({ action: 'setTestStatus', arguments: { status: 'failed', remark: 'Title not matched' } })}`)
  }

  await browser.close()
}
