Question

I have some Maven tests suite using Junit 4.12, that running well using 'mvn test' locally on my Mac, but not running at all on remote CI machine:

Both Maven versions are 3.6.0, and it's exactly the same project and branch.
Any idea?
Also, all tests name ends with "Test" and so are the tests classes.
Thanks!
