The Prevention of Errors through Experience-driven Test Efforts (PET)

Testing is a vital part of all software development but is a time consuming task, which hardly ever cleans out all the bugs in the software. The PET project approaches the testing problem by analysing problem reports from earlier versions of a specific software project and then using these bugs as a knowledge base for improving the efficiency of the testing process. Through such a rigorous analysis of problem reports from previous projects the companies behind the PET project have achieved a step change in the testing process of embedded real-time software. The measurable objectives have been to reduce the number of bugs reported after release by 50%, and reduce the hours of test effort per bug found by 40%. Both of these goals have been met. The actual numbers achieved were 75% less bugs reported, and a 46% improvement in test efficiency.
