Coverage 0% for implicit used netstandard project

[schrufygroovy]

I have a .NET core web API solution, that is covered by .NET integration tests (https://docs.microsoft.com/en-us/aspnet/core/test/integration-tests).

The web API solution is using some own library projects, that are netstandard projects and part of the solution. PDB file for the library does exist.

When I try to figure out the coverage then:

• the coverage for the controllers of the API and whole API project is correct.
• even the coverage of another "shared" API project that is implicitly used, is correct.

The coverage for the netstandard library that is used by the API is 0 %. Even though the exact line in the controller, that uses the library is marked as covered.

I have reduced the solution to the bare minimum and can still reproduce the issue:

Thanks for reporting this. We'll take a look asap.

updated to 3.0.1 -> still 0 % coverage

I see on test you're using msbuild integration, can you try with collectors one? https://github.com/coverlet-coverage/coverlet/blob/master/Documentation/VSTestIntegration.md

Maybe you're hitting known issue https://github.com/coverlet-coverage/coverlet/blob/master/Documentation/KnownIssues.md#vstest-stops-process-execution-early

thx @MarcoRossignoli
this seems to resolve the problem.

I missunderstood the known issue when I saw it. I thought I would receive a warning when it occures.

Unfortunately not because it's a kill from vstest plat and it's randomic, depends on how much time tests run.
