mvn test doesn't run any test (JUnit 4 or JUnit 5)

Question

I know what you'll think in the first place: "You should name your test classes with 'Test' in it etc." But the problem is: it's already the case. I did scroll every possible SO post and didn't find anything, so no, unfortunately, this is not a duplicate.

I even have a test class named TestPleaseWillYouRunMyTest and a test method called testPleaseTest().

When I run a "mvn test", the "target/test-classes" folder is well populated, so I really don't understand why my tests aren't run...

Just in case it would help understand the problem, here is my pom.xml:

Answer 1

Why you added testng, junit 4 and 5? first decide which testing framework you want to use

Answer 2

just to add my 5 cent to what khmarbaise said: if your tests sit in standard directory you don't need to add testSourceDirectory at all, this tag is for non standard places. Also you entry there is incorrect: src/test/java - this is definitely not the place where your test are.

Answer 3

mvn test

Only compiles the test classes but does not run the tests. In order to let the tests run use:

mvn verify
