Hi, I am new for Gradle and have a question wish someone can answer me 
How did Gradle regarding listing tests to be run with TestNG? For instance, I have
@Test(groups = {“helpers”}) for the class and @Test(groups = {“positive”}) and @Test(groups = {“negative”} for several methods,
how did Gradle know which one will be run first and so on OR I can run only one method.
I mean did it has a document such as XML file that Gradle can follow it? Thanks a lot.
Cheers,
Dan
