State-of-the-art testing approaches typically include different testing levels like reviews, unit testing, component testing, integration testing, system testing, and acceptance testing. There is also common sense that typically unit testing is done by developers (they are responsible to check the quality of their units at least to some extent) and system testing is done by professional independent testers. But, who is responsible to adequately test the architecture which is one of the key artifacts in developing and maintaining flexible, powerful, and sustainable products and systems? History has shown that too many project failures and troubles are caused by deficiencies in the architecture.Furthermore, what does the term architecture testing mean and why is this term seldom used?
To answer these questions, Peter describes what architecture testing is all about and explains a list of pragmatic practices and experiences to implement it successfully. He offers practical advice on the required tasks and activities as well as the needed involvement, contributions, and responsibilities of software architects in the area of testing – because a close cooperation between testers and architects is the key to drive and sustain a culture of prevention rather than detection across the lifecycle.
Finally, if we claim to be in pursuit of quality then adequate architecture testing is not only a lever for success but a necessity. And this results not only in better quality but also speeds up development by facilitating change and decreasing maintenance efforts.
