ScalaTest – A Popular DSL

Note

ScalaTest was introduced in Chapter 1, Setting up the Development Environment, but as we'll use it extensively in this lecture, we'll do a little recap here and make sure that everyone has a working ScalaTest environment.

In this section, we'll have a look at a popular library for testing your Scala programs, ScalaTest, and see how the library uses DSLs to allow its users to write readable tests in various styles.

The purpose of looking at ScalaTest is twofold. First off, ScalaTest is a widely used testing library for Scala projects, so you're likely to end up using it when you're using Scala professionally. Secondly, it's a good example of how to use DSLs to make your code more readable.

By the end of this section, you should be able to:

• Identify how to use ScalaTest in your own projects

• Identify the various styles that ScalaTest offers and be able to pick the one that's relevant to your project

• Write ScalaTest tests using the F latSpec style
