Maven is not finding scala tests - eclipse

Question

I have a scala test class but when I attempt to run using the Maven goal 'test'
the tests are not being run. I receive the Maven message "There are no tests to run." even though the tests are located in the scala test class. Do I need to add extra configuration ?
Here is my package setup :
Here is the output of the Maven "test" goal when run against the pom file :

Answer 1

Even though this is a very late reply, but I wrote it hoping that someone might get benefitted from it in case their scala unit test are not getting discovered. One of the major and silent culprit is the absolute path to the test classes. If there is a space in the name of any directory on the path, scalatest won't pick it up. Rename such directories for successful running of unit tests.

Answer 2

What's your test class name? Maven can be pretty picky and by default I think it requires the class name to end in 'Test'.
See my previos post:
Maven won't run tests
