Conditional unit tests

How to run xunit tests conditionally depending on the environment that is running the tests

Last updated 3 years ago

Turns out that there aren't any conditional FactAttribute in , but you can pretty much copy wholesale the extensions created by the .

It allows you to do things like:

[SkipOnCI]
[ConditionalFact]
public async Task SomeTest()

to avoid running a test entirely if you're on CI. the implementation didn't take into account CI builds running via GH actions/workflows, so I tweaked the like so to also consider the commonly used CI envvar too:

public static bool OnCI() => 
   (bool.TryParse(Environment.GetEnvironmentVariable("CI"), out var ci) && ci) || 
   OnHelix() || OnAzdo();

I didn't think it was necessary to create an OnGitHub method since the envvar is just CI and well, the method is already called OnCI :)

Another alternative is using the .

xunit
ASP.NET Core team from their repo
OnCI() method
Xunit.SkippableFact nuget package
