Mutation Testing

Better Code by Making Bugs

Filip van Laenen
Are you already using TDD, measuring test coverage, and running static code analysison your code? Maybe you're wondering whether there's a “next level” in code quality? If so, you should check out this book and learn about mutation testing. Mutation testing changes your source code and then checks back whether your unit tests can catch the changes, just like they should catch bugs. Can they? Find out how it works, and why it works in this book.

Earn $8 on a $10 Purchase, and $16 on a $20 Purchase

We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.

(Yes, some authors have already earned much more than that on Leanpub.)

In fact, authors have earned over $14 million writing, publishing and selling on Leanpub.
