Given that StraceBase doesn't even check specific methods any more I don't see that the stacktrace length check in these tests serves any purpose. As long as only the expected classes appear then the actual methods (and number thereof) seems irrelevant.

But in terms of fixing this in the same way as the other test this seems fine.

Note that the main test comments on this test (and likely the others) is no longer accurate.

Thanks.
