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) designed specifically 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.

• Get an overview of Test-Driven Development
• Start a simple project with SBT and create tests before you write code
• Dive into SBT's basic commands, interactive mode, packaging, and history
• Use ScalaTest both in the command line and with SBT, and learn how to incorporate JUnit and TestNG
• Work with the Specs2 framework, including Specification styles, matchers DSLs, and Data Tables
• Understand mocking by using Java frameworks EasyMock and Mockito, and the Scala-only framework ScalaMock
• Automate testing by using ScalaCheck to generate fake data
