When tests fail to load due to a missing dependency (e.g. referenced project not set to local copy), there is no error displayed or logged anywhere at all.
Created attachment 20437 [details]
I added sample project with unit test project where I disabled local copy, but everything keeps working fine.
Can you give more details on how to reproduce this?
Check out https://github.com/mono/t4 and disable local copy on the Mono.TextTemplating.Tests->Mono.TextDemplating reference before building.
I can reproduce this. In Unit tests pad test project has 0 unit tests and no errors.(It should show error instead)
I'm moving this to 15.4 since there I will be implementing https://github.com/Microsoft/vstest and will address this problem there
Switch to vstest was moved to 15.5 hence so is bug
VSTest integration was finished for 15.5, but NUnit projects continue to use existing logic for now, maybe we change that for 15.6 to also use VSTest, hence moving to 15.6 milestone.
