Mutation Testing: Did my test break my code ? 🤔
Conference (INTERMEDIATE level)
Room 5

Last week, you spend the last 2 days writing plenty of tests. Your code coverage was 100% so you thought you could safely leave on a weekend ✈️🏖️

But on Monday, your inbox is flooded with new bug reports. What happened!? What did you miss?

In this talk, we present Mutation testing which is a technique to evaluate the quality of tests beyond the number of lines tested. Mutation testing is based on creating a changed copy of the code to ensure a software test suite is able to detect the changes.

How do we create Mutation tests? How does it work? What are the advantages and drawbacks of Mutation tests? All these questions will be answered with a demo in this talk.

Come and discover what Mutation testing is and how can we implement it to ensure the quality of our test suites.

Most of us do code reviews very often if not daily. However, how can we tell whether we are good reviewers or not? Do we review a code as robots? Do we keep in mind that we are reviewing the code of someone who invested time and knowledge to write this code, and thus deserves to get respectful feedback?

In this talk, we present the code review best practices and we answer the following questions: What to look for in a code review? How can we write useful reviews?

Furthermore, we explain the key tips for writing respectful and constructive code review feedback. To discover more about all these points and more, come and see our talk.
