I use Playwright for testing in .NET with Azure DevOps. A CI pipeline performs builds. A CD pipeline deploys our product and runs the tests.
Playwright needs the browser binaries available in
%USERPROFILE%\AppData\Local\ms-playwright The documentation says to run
bin\Debug\netX\playwright.ps1 install to download them. In my case
playwright.ps1 did not exist and test were unable to run. I solved it in my CI pipeline like this.
- task: PowerShell@2 displayName: Download Playwright Browsers inputs: targetType: inline script: >- cd <directory with the playwright .csproj> dotnet build dotnet tool install --global Microsoft.Playwright.CLI playwright install ... build remaining projects, code analysis etc. etc. ... - task: CopyFiles@2 displayName: 'Copy Files to: $(build.artifactstagingdirectory)' inputs: SourceFolder: $(system.defaultworkingdirectory) Contents: '**\bin\$(BuildConfiguration)\**' TargetFolder: $(build.artifactstagingdirectory) CleanTargetFolder: true
This creates the script, downloads the browsers and includes the script into the build artifact for other stages and pipelines.
If your CD pipeline uses different machines or users, you need to run
playwright.ps1 install in the CD pipeline before starting tests.
