I loved your analogy using mutants to explain how this mutation testing works. I think it's true that I think if you have a very low coverage of kind of like the poor test suite you will not be able to kill the mutants so to speak right? Your test will always pass because you don't cover enough. Another technique that you mentioned in your book is called property testing. How does this differ and what is property testing? Yeah, so property based testing is the way of writing a test that is different from the way we write normal testsright. So usually when we write a normal test which I call example based test in the book.
“An effective developer is an effective software tester. As a developer, it’s your responsibility to make sure what you do works. And automated testing is such an easy and cheap way of doing it."
Mauricio Aniche is the author of “Effective Software Testing”. In this episode, Mauricio explained how to become a more effective software developer by using effective and systematic software testing approaches. We discussed several such testing techniques, such as testing pyramid, specification-based testing, boundary testing, structural testing, mutation testing, and property testing. Mauricio also shared his interesting view about test-driven development (TDD) and suggested the one area we can do to improve our test maintainability.
