Improve your tests quality with Mutation Testing
May 23
45 minutes
Talk
English

Abstract: Unit testing ensures your production code is relevant. But what does ensure your testing code is relevant? Come discover mutation testing and make sure your never forget another assert again.

In the realm of testing, the code coverage metrics is the most often talked about. However, it doesn’t mean that the test has been useful or even that an assert has been coded. Mutation testing is a strategy to make sure that the test code is relevant.

In this talk, I will explain how Code Coverage is computed and what its inherent flaw is. Afterwards, I will describe how Mutation Testing work and how it helps pointing out code that is tested but leave out corner cases. I will also demo PIT, a Java production-grade framework that enables Mutation Testing on a simple code base. If time allows, a demo will also show how PIT can be integrated with SonarQube.

Abstract: Spring Boot is a product from Spring, that provides many configuration defaults for a new Spring project, so that one can set up a project in minutes.

However, this is only one of the many features of Spring Boot. One of its module also provides many important Non-Functional Requirements out-of-the-box: monitoring, metrics, exposing those over HTTP, etc. In this presentation, I’ll demo some of those, that will make DevOps more than a little happy.
