In “SKB Kontur” there are many products that have been developing for 5 years or more, and we continue to develop them. During this time, the product accumulates a lot of autotests at all possible levels, and people in teams change. This leads to the fact that neither the developers nor the testers know exactly what their autotests are checking.
I will tell you what problems this ignorance leads to. I will also tell you about “the coverage map” tool. How we implanted it and how we use it in order to quickly determine the autotest coverage of functionality.
