One of the social diseases of the testing craft is the obsession with repetition. Is that test repeatable? Is that test process repeatable? Have we repeated those tests? These questions are often asked in a tone of worry or accusation, sometimes accompanied by rhetorical quips about the importance of a disciplined process-- without explanation of how discipline requires repetition.In order to replace obsession with informed choice, we need a way to consider a siutation and decide if repetition is warranted, and how much repetition. I have found that the analogy of a minefield helps me work through those considerations.
