JUnit 4.8.1 / Maven trivial test not working

Although I tried out all suggestions I found, I still can't get the most trivial JUnit test running. The error message basically repeats saying "junit.framework.AssertionFailedError: No tests found in project002.trivial.TestClassTest".

You may inspect a snapshot of my IDE or download the zipped project.

Here is my pom.xml:

There's something wrong with your testcase. When you extend Testcase, it will always be executed using Junit 3.x, thus you need to prefix your test method with "test".

If you want to use junit 4.x, remove "extends Testcase", then annotate your test method with @Test.

This one runs using Junit 3.x, and it will not work because your test method is not prefixed with "test":-

public class TestClassTest extends TestCase {

    @Test
    public void isThisReallyTrue() {
        assertTrue(true);
    }
}

This one will run in Junit 4.x:-

public class TestClassTest {

    @Test
    public void isThisReallyTrue() {
        assertTrue(true);
    }
}
