How to pass parameters to the dotnet test command while using NUnit

If you want to avoid a runsettings file, you can use this workaround

Tests.cs

string browser = System.Environment.GetEnvironmentVariable("Browser") ?? "chrome";

Note: Selection of browser is through an environment variable. Defaults to Chrome if unprovided.

Tests.bat

set DIR=%~dp0

chdir /d %DIR% 

SETLOCAL

SET Browser=firefox

dotnet test project.dll --filter TestCategory="Sanity"

If you want to launch the test from an Azure DevOps (fka VSTS or TFS) pipeline, you can simply use the $(...) notation to inline variables

SET TestPassword=$(TestPassword)

dotnet test $(Build.SourcesDirectory)\MyCompany.MyProduct.UITests\MyTest.csproj --configuration $(BuildConfiguration) --collect "Code Coverage" --logger trx --results-directory $(Agent.TempDirectory)
