Reducing wasted development time via continuous testing

Reducing wasted development time via continuous testing
Testing is often performed frequently during development to ensure software reliability by catching regression errors quickly. However, stopping frequently to test also wastes time by holding up development progress. User studies on real development projects indicate that these two sources of wasted time account for 10–15% of development time. These measurements use a novel technique for computing the wasted extra development time incurred by a delay in discovering a regression error. We present a model of developer behavior that infers developer beliefs from developer behavior, and that predicts developer behavior in new environments — in particular, when changing testing methodologies or tools to reduce wasted time. Changing test ordering or reporting reduces wasted time by 4–41% in our case study. Changing the frequency with which tests are run can reduce wasted time by 31–82% (but developers cannot know the ideal frequency except after the fact). We introduce and evaluate ...
