Mutate and Test Your Tests
by Benoit Baudry
I am extremely proud and happy that my talk on mutation testing got accepted as an early bird for EclipseCon Europe 2017.
We will talk a lot about software testing at the project quality day. In this talk, I will focus on qualitative evaluation of a unit test suite. Statement coverage is commonly used to quantify the quality of a test suite: it measures the ratio of source code statements that are executed at least once when running the test suite. However, statement coverage is known to be a rather weak quality indicator. For example, a test suite that covers 100% of the statements and that has absolutely no assertion is a very bad test suite, yet is considered of excellent quality according statement coverage.
