Use Your Host Computer--To Test

What if we could find a way that would allow us to create tests that worked as well (or better) in an open system environment. This would make the same tests available to anyone and not restrict them to only the tester. No matter haw hard you work in the closed test environment you can never get more work done then you are capable of. But
if we could run in an open test environment we would be able to multiplex the testing
impact on the product many times over. To use a phrase from Object Oriented
Programming we could “write once – use many times.”
