/**
 * Implementation trait for class PathAnyFreeSpec, which is
 * a sister class to org.scalatest.freespec.AnyFreeSpec that isolates
 * tests by running each test in its own instance of the test class, and
 * for each test, only executing the path leading to that test.
 * 
 * 

* PathAnyFreeSpec 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 PathAnyFreeSpec into some other class, you can use this * trait instead, because class PathAnyFreeSpec does nothing more than * extend this trait and add a nice toString implementation. *

* *

* See the documentation of the class for a detailed * overview of PathAnyFreeSpec. *
