a more convenient require method for running TESTS ONLY. THIS MODULE PROBABLY DOES NOT WORK IN THE WAY YOU EXPECT IT TO WORK ALL THE TIME. I REPEAT: IT HAS DIFFERENT BEHAVIOR BASED ON HOW IT'S BROUGHT IN AS A DEPENDENCY THAT WILL CAUSE YOU HEADACHES. ESPECIALLY IF YOU USE IT IN TWO MODULES WHICH DEPEND ON ONE ANOTHER. (this is because of the way npm optimizes dependencies, and this module doesn't address that, since it's for testing only.).
