I’ve been on teams with way too little and (heresy) way too much testing. There have been lots of talks about how you should test more, but I’m going to dare to talk about when you should test less. Too much testing can lead to backlash, gridlock, morale problems, and poor velocity. Of course lack of testing can lead to bad design, gridlock, morale problems, and poor velocity. The level of testing a team can support depends on many factors including: team size, developer buy in, managerial approval, company size, IT support, and testing experience.
