Functions and methods (also in Python standard library and third party code) can be wrapped so that when they are called, the wrap is invoked first. Depending on the wrap, the execution of the original function can be omitted, or the function can be called arbitrarily many times. Wraps are able to modify the arguments and the return value of the original function. In the terminology of aspect-oriented programming, the library allows applying advices (wraps) to call join points of methods and functions in around fashion.http://www.developerhell.com/out/Behavior_driven_Testing_with_RSpechttp://www.developerhell.com/out/Behavior_driven_Testing_with_RSpecTesting fever has infected the Ruby programming community, and the infection is spreading.
