Mutation Testing - Pixels Camp 2019

Mutation Testing - Pixels Camp 2019

Mutation testing has been evolving into a real candidate to become the de facto metric for assessing the quality of a test suite, defying the throne that has been occupied by code coverage until now.

The concept of mutation testing is quite simple: mutations are introduced on the codebase and the test suite is run against the mutated code. If your test suite is strong, then it should catch the mutation, by having at least one test failing.

In this talk I plan to show how coverage by itself doesn't guarantee quality on the test suite, and how mutation testing can effectively find bugs on your code and tests.
