/**
* Implementation trait for class TestNGSuite, which represents
* a suite of tests that can be run with either TestNG or ScalaTest.
*
*
* TestNGSuite is a class, not a
* trait, to minimize compile time given there is a slight compiler overhead to
* mixing in traits compared to extending classes. If you need to mix the
* behavior of TestNGSuite into some other class, you can use this
* trait instead, because class TestNGSuite does nothing more than
* extend this trait.
*
*
*
* See the documentation of the class for a detailed
* overview of TestNGSuite.
