Conditionally ignoring tests in JUnit 4

by

The JUnit way is to do this at run-time is org.junit.Assume.

 @Before
 public void beforeMethod() {
     org.junit.Assume.assumeTrue(someCondition());
     // rest of setup.
 }

You can do it in a @Before method or in the test itself, but not in an @After method. If you do it in the test itself, your @Before method will get run. You can also do it within @BeforeClass to prevent class initialization.

An assumption failure causes the test to be ignored.

Edit: To compare with the @RunIf annotation from junit-ext, their sample code would look like this:

@Test
public void calculateTotalSalary() {
    assumeThat(Database.connect(), is(notNull()));
    //test code below.
}

Not to mention that it is much easier to capture and use the connection from the Database.connect() method this way.
