JUnit setUp gets invoked TWO times with one test and messing up Powermock expectNew

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
     }
  }

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

Firstly you need to make the setup method as "static". Referring to this answer here, https://stackoverflow.com/a/5978702/964446

you cannot do both extends TestCase and use annotations, as they use different runners. So when JUnit sees extends TestCase it will most probably use the old runner, where-in the @Test annotation will be overlooked.

You can simple make the setup method as static without extending the TestCase and use @Test annotations, this should work as per JUnit4

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.

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.
