Master's thesis in Software Development: Optimizing mutation testing with Stryker
Mutation testing is a method to measure the effectiveness of unit tests. Stryker Mutator, an open-source mutation testing framework by Info Support, is already fast, but there is room for improvement. Your task is to identify areas where the performance can be increased and develop methodologies to speed up mutation testing.

Mutation testing frameworks measure the effectiveness of unit tests by inserting mutants (bugs) into the production code and running the unit tests. If the tests pass for a given mutant, there might be a missing test case. If at least one of the tests fails, the mutant is 'killed'. The percentage of killed mutants is referred to as the 'mutation score' and is a metric for test effectiveness.
At Info Support, we maintain Stryker Mutator, an open-source mutation testing framework. It consists of 3 flavors: Stryker.NET (C#), Stryker4s (Scala), and Stryker (for JavaScript and friends). For more information, see.
There are many ways to introduce mutants into the source code. Mutating sources statement by statement is a logical choice, but not good for performance as the codebase needs to be recompiled or reloaded after every mutation. Mutation switching can provide a solution to speed up the process. With mutation switching, all mutants are compiled into the codebase at once and switched on one-by-one at runtime. In the case of Stryker.NET and Stryker4s, this has resulted in a significant performance boost.
We would like to increase the performance of Stryker even further. Research will focus on finding areas where improvements can be made and/or developing methodologies for speeding up mutation testing.
