Runtime: `build -test` won't actually run tests as said in the docs?

[Gnbrkm41]

https://github.com/dotnet/runtime/blob/master/docs/workflow/testing/libraries/testing.md says:

The following builds and runs all tests in release configuration:
build.cmd/sh -subset libs -test -c Release

However when I do build -subset libs -runtimeConfiguration Release -test it doesn't appear to build tests neither run the tests; From what I see it seems to build the libraries part, and ends.

In addition, when I specify -testnobuild it doesn't seem to respect it as it does actually build the libs component.

The subset is wrong in the docs. It should be libs.tests.

@ViktorHofer btw, is it possible to build everything from scratch and run tests at once?, e.g.

build -subset Mono+Libs+Libs.Tests -test

or it should be

build -subset Mono+Libs
build -subset Libs.Tests -test

?

@ViktorHofer btw, is it possible to build everything from scratch and run tests at once?, e.g.

I think build.cmd mono+libs+libs.tests -test should work fine as long as mono doesn't have a test subset.

I think build.cmd mono+libs+libs.tests -test should work fine as long as mono doesn't have a test subset.

Also, do we need to pass /p:RuntimeFlavor=mono for that?

[ViktorHofer]

No, that's auto-detected: https://github.com/dotnet/runtime/blob/master/eng/Subsets.props#L52.

Good to know 😄 thanks!
