Answer 1

I ran into this issue with Ubuntu 20.04, Java 11.0.8-zulu, and Intellij 2020.2.

Upgrading Junit from 5.5.2 to 5.6.2 and Junit Platform from 1.5.2 to 1.6.2 solved it for me.

That seemed odd to me, so I switched the versions back, which now also works. I think some sort of cache invalidation is likely the best explanation, albeit the corresponding button for this didn't work for me.

So basically, what is said here https://stackoverflow.com/a/58687202/6476706 (I tried to comment there but can't...).

Anyway, still an issue in 2020, maybe this helps someone.
