I have some normal JUnit tests and one file using Spek. I am trying to have all tests run regardless of whether they are Spek or regular JUnit. Now I can only get the Spek to run. I am using Maven. My output looks like this:

Looks like it is acknowledging all the tests, but decides only to run the Spek one. Is this a known limitation or am I doing something wrong?
