Why isn't my @BeforeClass method running?

Question

I have the following code:

    @BeforeClass
    public static void setUpOnce() throws InterruptedException {
        fail(\"LOL\");
    }

Answer 1

the method must be static and not directly call fail (otherwise the other methods won't be executed).

The following class shows all the standard JUnit 4 method types:

public class Sample {

    @BeforeClass
    public static void beforeClass() {
        System.out.println("@BeforeClass");
    }

    @Before
    public void before() {
        System.out.println("@Before");
    }

    @Test
    public void test() {
        System.out.println("@Test");
    }

    @After
    public void after() {
        System.out.println("@After");
    }

    @AfterClass
    public static void afterClass() {
        System.out.println("@AfterClass");
    }

}

and the ouput is (not surprisingly):

@BeforeClass
@Before
@Test
@After
@AfterClass
