Talk Description
As a software engineer, you know how important it is to have a well-equipped set of automated tests. Such a set will help you to make changes to the code quickly and with confidence. Therefore, engineers agree on the percentage code to be covered by automated testing. Automated testing verifies the operation of the source code, but how do you verify the operation of your tests?
During this session, we explain which problems can occur if the engineers concentrate solely on achieving the agreed coverage rate. For example, a high degree of coverage is not a guarantee of a well-tested application. In addition, we explain what mutation testing and how to test with mutation testing which code is still insufficiently tested. During the session, we demonstrate mutation testing using Stryker. Stryker is an open source mutation test framework that we have developed for performing mutation testing on JavaScript projects.
