Junit check: failure value ("not yet implemented") ;?

Question

What is the meaning of this piece of code?

eg.

@Test
    public void testGetDiameter() {
        **fail("Not yet implemented");**
    }

Answer 1

Using the Eclipse IDE, if you create JUnit TestCase stubs, they will add test methods with fail("Not yet implemented"). So if you forgot to add a real implementation, the test script will fail and the error or confirmation error will appear as "not yet implemented."
