TDD and Mutation Testing (Daniel Moka)

Code coverage is not a quality metric. You can have 100% code coverage without any test assertions. Code coverage can help to detect untested areas of the code, but it doesn't tell anything about the tested areas. How can we measure the quality of our tests then? The answer is: Mutation Testing.

In this session I will explain what Mutation Testing is and how you can use it to improve the quality of your tests. Also, I will also demonstrate why Test-Driven Development is the best way to write code that is properly covered by our tests. Don’t write tests to increase code coverage. Write tests to gain confidence.
