Problems with execution of JUnit4 TestCases and TestSuite

Question

@parameters method is executed before @beforeclass method

I am facing some trouble with JUnit 4 TestsUites and Parameterized Tests.

In my Suite I want to set a SystemProperty like this:

@RunWith(Suite.class)
@SuiteClasses({ParameterizedTestCase.class })
public class TestSuite {

     @BeforeClass
     public static void setUpSuite() {
        System.out.println("suite");
        System.setProperty("propertyToSet", "propertyToSet");
     }

}

In the ParameterizedTestCase I declared the generateParams() to print the Property like this:

@RunWith(Parameterized.class)
public class ParameterizedTestCase{
     @Parameters
     public static Collection<Object[]> generateParams() {
     System.out.println("Parameter: " + System.getProperty("propertyToSet"));
     }

    @Test
    public void testSomething() {
        //doSometing
    }
}

The Output i get is as follows:

Parameter: null
suite

So the Methods are invoked in the wrong order. I thought, that the BeforeClass of the Suite is invoked before all TestClasses.

How can I fix this problem. I need to set a Parameter in the Suite, which will be used by several TestCases. But the TestCases don't know from which Suite they are invoked. So I prefer something like a Systemproperty.

Thanks for your Help
