About the Author

Filip van Laenen
Filip van Laenen

Filip van Laenen has been a professional software developer at the Norwegian software company Computas since 1997. He started as a Java and Smalltalk developer, but over the course of the years held other roles in a large number of projects, both small and large, like tester, QA responsible, acting project leader, business analyst, architect and technical project leader. In his spare time he likes to experiment with code and new software development tools, and that's how he discovered mutation testing a couple of years ago. Since then, he has used it in some of his hobby projects, but also at work. He has held a number of presentations about mutation testing at software conferences.

Within 60 days of purchase you can get a 100% refund on any Leanpub purchase, in two clicks.

Now, this is technically risky for us, since you'll have the book or course files either way. But we're so confident in our products and services, and in our authors and readers, that we're happy to offer a full money back guarantee for everything we sell.

You can only find out how good something is by trying it, and because of our 100% money back guarantee there's literally no risk to do so!
