Question

Very strange behaviour in my test.

  public class MyTestclass {
     @Before
     void setUp(){
        //do some setup, but hu i get called twice
        //here i do some try catch thing to get the stacktrace...
     }

     void testOnlyOneTest(){
        //make the testing, i get called only once
     }

     @After
     void tearDown(){
        //do some destroy things,... i get called twice too
     }
  }

StackTrace:

Any ideas why my setUp gets called twice?

I do some mocking in the setUp and after a verify i get the expect 2 times called 1 times, thing so my tests fail.

i am using powermock 1.4.8, junit 4.4, and the easymock framework

Was it helpful?

Solution

Does your class extend TestCase? It doesn't appear to in the example but I'm just trying to think what could be causing this. If it did then it would ignore the annotations and consider every method that starts with the word test as a test case causing you to have possibly more tests than you think.

OTHER TIPS

I think you want to use @BeforeClass instead of @Before. @Before gets run before each method annotated with @Test, whereas @BeforeClass only runs once before all @Test methods.
