AllBooleanCombinationsSource arguments provider

[tomerr90]

A common use case we have is a test that take a bunch of boolean flags a check very slightly (mostly in expected value) based on this flag.
Classic for a ParameterizedTest, which is what we use today, but for the source we currently use CsvSource with the boolean options:

@ParameterizedTest
@CsvSource({
   "true, true",
   "true, false",
   "false, true",
   "false, false"
})
public void testMethod(boolean flag1, boolean flag2)

Which is annoying, verbose and error-prone.
So I wanted to implement an annotation like @AllBooleanCombinationsSource(int) that takes the number of boolean params and generate all possible combinations.
Though this might be a bit too specific, so wanted to get your opinion, is that something that you think belongs in Junit?

Take a look at the Cartesian product support in JUnit Pioneer.

I think that might suit your needs.

Thanks @sbrannen! yeah Im aware of that, we didnt want to add a dependency just for one annotation

May I try?

Team Decision: We advise to use the feature from Pioneer and won't include this in Jupiter core for the time being.
