Using @Factory annotation + PowerMock's @ObjectFactory

[aiman86]

Hello,

I'm trying to use @Factory annotation to build dynamic test instances, but I would like to also use PowerMock in my test. It seems that this is currently undoable  - or I may be doing something wrong. Can you please take a look ? Below is a simplified version of the code that exhibit the same issue:

@PrepareForTest({ FileSystem.class })

@PowerMockIgnore("javax.management.*")

@SuppressWarnings("all")

public class SimpleTestCase extends PowerMockTestCase {

   @Factory(dataProvider="testData")

   public Object[] testInstanceFactory(Object param) {

       return new Object[]{ new SimpleTestCase() };

   }

    @Test

   public void testProcessEvents() throws Exception {

       Assert.assertTrue(true);

   }

    @DataProvider(name = "testData")

   public Object[][] testData() {

        return new Object[][] { { "param" } };

   }

    @ObjectFactory

   public IObjectFactory getObjectFactory() {

       return new PowerMockObjectFactory();

   }

}

To get the above to run, I can do one of the following:

• Remove the the @ObjectFactory method and the inheritance from PowerMockTestCase
• Or remove the PrepareForTest annotation 

However, naturally this will disable PowerMock features which I critically need. So, I'm not sure how to use both PowerMock and TestNG's @Factory to create dynamic test instances. Are these two incompatible currently or is there another way to accomplish this?

Thank you

TestNG's Factory should be sufficient to create dynamic tests, why would u need other supporting library?
