Why isn't my @BeforeClass method running?

Question

I have the following code:

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

And various other methods that are either @Before, @After, @Test or @AfterClass methods.

The test doesn't fail on start up as it seems it should. Can someone help me please?

I have JUnit 4.5

The method is failing in an immediate call to setUp() which is annotated as @before. Class def is :

public class myTests extends TestCase { 

Answer 1

do NOT extend TestCase AND use annotations at the same time!
If you need to create a test suite with annotations, use the RunWith annotation like:

@RunWith(Suite.class) @Suite.SuiteClasses({ MyTests.class, OtherTest.class }) public class AllTests {     // empty }   public class MyTests {  // no extends here     @BeforeClass     public static void setUpOnce() throws InterruptedException {         ...     @Test     ... 

(by convention: class names with uppercase letter)

Answer 2

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
