Introduction to PlayWright

I'm starting to learn Playwright. It is a promising test automation tool. The great thing is that you can use many programming languages to use PlayWright. The languages supported by the Playwright are given below:

1. JavaScript
2. Java
3. C#
4. Python

PlayWright also provides excellent tools for debugging tests in real-time. You can also produce test run recordings and logs with detailed screenshots. Other than UI testing, you can also test APIs with Playwright.

How to enable debugging through PowerShell:

$env:PWDEBUG=1

How to disable debugging through PowerShell:

$env:PWDEBUG=0

How to see trace (if enabled) through PowerShell:

.\playwright.ps1 show-trace

How to enable headless mode through Powershell:

$env:HEADED="1"

How to disable headless mode through Powershell:

$env:HEADED="0"

How to run tests with specific run settings file

dotnet test --settings:chromium.runsettings

Important note about running tests via GitHub Actions/Azure, etc.

Running on Ubuntu VMs is headless mode, which is supported by default. To run non-headless mode, you must set up X GUI. Extra frills!

How to launch code-generator

.\bin\debug\net6.0\playwright.ps1 codegen google.com

How to launch trace viewer

.\bin\Debug\net6.0\playwright show-trace .\bin\Debug\net6.0\playwright-traces\PlaywrightTest01.PlaywrightAutomation01.OpenGoogleAndSearchTest.zip

Note

--save-storage With npx playwright codegen allows you to preserve authenticated state by saving cookies and localStorage. Super handy for recording tests with common authentication steps!

Enable verbose for API testing

$env:DEBUG="pw:api"
