Maven does not find JUnit tests to run

manpreet Best Answer 2 years ago

I have a maven program, it compiles fine. When I run mvn test it does not run any tests (under TESTs header says There are no tests">tests to run.).

I've recreated this problem with a super simple setup which I will include below as well as the output when run with -X.

The unit tests run fine from eclipse (both with its default junit package and when I instead include the junit.jar downloaded by maven). Also mvn test-compile correctly creates the class under test-classes. I am running this on OSX 10.6.7 with Maven 3.0.2 and java 1.6.0_24.

Here is the directory structure:
