10 Performance testing

This chapter covers

How to manage expectations with performance testing
How to plan and implement a performance test
How to execute a performance test and analyze the results

Performance testing is an excellent example of why we should be motivated by quality characteristics in our testing strategy. Typically, performance is thought of as a “nonfunctional requirement,” but as my colleague Richard Bradshaw once said, “If my application’s features are all working, but it takes over a minute for it to respond to me when I’m using it, then it doesn’t feel very functional to me.”

The problem with the distinction between “functional” and “nonfunctional requirements” is that it can sometimes imply a hierarchy, or priority, over ...
