Testing.Platform test runner with solution file

[ladeak]

I have a solution with 3 test projects. In the past I could do: dotnet test MySolution.sln --configuration Release in a CI.

When I migrate to the TestRunner, what is the best way to execute all tests in the solution? I would like all tests projects to execute but not my other console apps in the solution. Can I avoid listing all test projects?

Something like

dotnet build MySolution.sln --configuration Release
dotnet run ?

dotnet test is still the recommended way to run all your tests. Are you facing some issue with it?

[ladeak]

No, but I'd like to try to the new runner. For one of my test projects I measure ~20% improvement, which made me exited enough to try it.

[Evangelink]

The new platform does integrate with dotnet test, please do check the extra property is turned on (see https://learn.microsoft.com/dotnet/core/testing/unit-testing-platform-integration-dotnet-test#dotnet-test---microsofttestingplatform-mode). If you are using MSTest.Sdk then no extra step is required :)

Please keep me posted about the perf you are measuring, it's always good to get more data!

Actually for test projects using xunit. On GitHub they used to before 20 sec, now 14 sec. Similar improvements locally.
before:

after:

I suppose the --no-build helps a few seconds too, but without it with xunit there is a few seconds gain as well.
