And now for something completely different . . . Monty Python's Flying Circus

revolutionized comedy and brought zany British humor to a world-wide

audience. However, buried deep in the hilarity and camouflaged in its twisted

wit, lie many important testing lessons—tips and techniques you can apply to

real world problems to deal with turbulent projects, changing requirements,

and stubborn project stakeholders. Rob Sabourin examines some of the most

famous Python bits—“The Spanish Inquisition” telling us to expect the

unexpected, “The Dead Parrot” asking if we should really deliver this product

to the customer, “The Argument” teaching us about bug advocacy, “Self

Defense Against Fresh Fruit” demonstrating the need to pick the right testing

tool, and a host of other goofy gags, each one with a lesson for testers.

• How to test effectively with persistence

• Make your point with effective communication

• Keys ways to clarify project goals and requirements
