Testing in Scala. Scala. Tools for Behavior-Driven Development 14060

If you build your Scala application through Test-Driven Development, you'll quickly see the advantages of testing before you write production code. This hands-on book shows you how to create tests with ScalaTest and the Specs2—two of the best testing frameworks available—and how to run your tests in the Simple Build Tool (SBT) specifically designed for Scala projects.

By building a sample digital jukebox application, you'll discover how to isolate your tests from large subsystems and networks with mocking code, and how to use the ScalaCheck library for automated specification-based testing. If you're familiar with Scala, Ruby, or Python, this book is for you.
