People who know me and my work probably know my emphasis on good test design for successful test automation. I have written about this in “Key Success Factors for Keyword Driven Testing“. In the Action Based Testing (ABT) method that I have pioneered over the years it is an essential element for success. However, agreeing with me in workshops and actually applying the principles in projects turn out quite often to be two different things. Apart from my own possible limitations as a teacher, I see at least one more reason: the way the testing is involved in the development projects.
Divide and conquer was a strategy successfully employed by ancient Persian kings against their Greek enemies. It is a strategy that can still be used successfully today. Fundamentally, by dividing something into smaller more manageable pieces (in the case of the ancient Persians, they divided the Greek city states), it becomes much more manageable.
