Title Body

I'm using "parametrized" feature of junit 4 and I noticed that @parameters method is executed before @beforeclass method. This is creating a problem for me because the parameters i'm passing to the test cases via @parameters depends on the code initialize in the @beforeclass method. For example @RunWith(Parameterized.class) public class TestOtherClass { String argument; private static boolean initializeThis; public TestOtherClass(String parameter) throws Exception { argument=parameter; } @BeforeClass public static void doSetup() { System.out.println("Doing setup before class..."); initializeThis=true; // true or false, based on some condition } @Test public void otherTest() { System.out.println("Other test: " + argument); } @Parameters public static Collection<Object[]> getData(){ System.out.println("Inside parameter"); String addThis; if(initializeThis) addThis="adding true"; else addThis="adding false"; Object[] para1 = new Object[]{"First parameter :: " + addThis}; Object[] para2 = new Object[]{"Second parameter :: " + addThis}; Collection<Object[]> classNames = new ArrayList<Object[]>(); classNames.add(para1); classNames.add(para2); return classNames; } } Now, I'm initializing variable "initializeThis" to true in @beforeclass method but (surprisingly) when I executed the test case it prints Other test: First parameter :: adding false Other test: Second parameter :: adding false That is something not expected. My question is; is there any way to execute the @beforeclass method before @parameters, can we do this is in junit 4?
