> Hi!
> I read that you can do attached tests by installing the test-jar (from http://maven.apache.org/guides/mini/guide-attached-tests.html) and then using dependenciesToScan configuration option to scan the test-jar dependency for tests and run them. This gave me an idea of providing a test jar that I could test implementation of my interfaces without having to write repeated tests for them (I load the implementations via ServiceLoader mechanism) . I've got a project for that at https://gitlab.com/Dragas/eternal-witness. Mind you the project does use project jigsaw features.
> While experimenting, I ended up extracting the "api" tests into its own module, but the issue continues to remain.
> Trying this approach I seem to observe an interesting behavior. Surefire plugin does indeed find that there are PlayerServiceTest and DeckServiceTest files on the dependency graph, but it fails to load them for some reason. Perhaps it does not patch the test module with the dependency module? I have attached the JVM dumpstreams from my experimenting.
