/**
* Implementation trait for class AsyncFunSuite, which represents
* a suite of tests in which each test is represented as a function value.
*
*
* AsyncFunSuite 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 AsyncFunSuite into some other class, you can use this
* trait instead, because class AsyncFunSuite does nothing more than
* extend this trait and add a nice toString implementation.
*
*
*
* See the documentation of the class for a detailed
* overview of AsyncFunSuite.
