Unit testing frameworks

We have many unit testing frameworks to test Play, Scala, and Akka-based applications. We can use the following frameworks:

Spec2
ScalaTest
ScalaTest plus
ScalaCheck
ScalaMock
Mokito
Akka Toolkit's testing modules

In this chapter, we will use mainly ScalaTest, and its related frameworks to test our applications, and also Akka Toolkit's testing modules.

ScalaTest

ScalaTest is one of the popular unit testing frameworks for Scala-based projects. It is an open source, free software released under the Apache 2.0 license, developed by Bill Venners and Artima. It also supports the unit testing of Java-based applications.

It supports multiple testing styles, such as WordSpec, FlatSpec, FreeSpec, and PropSpec. We can choose the right spec to suit our project requirements.

ScalaTest's latest stable version is 3.0.4, and we can find its documentation at http://doc.scalatest.org/3.0.1/#package. Its official website is www.scalatest.org, and its source code is available at https://github...

Learn Scala Programming

Learn Scala Programming

Today's Scala is quite different from its earlier versions. The second version of the language is more than twelve years old and has undergone multiple changes related to supported features and library implementation. This book addresses both technical and architectural changes by providing a comprehensive guide to the redesigned standard library and collections as well as covering in-depth type system and first-level support for functions. Finally, you will build projects using the knowledge learned previously to build microservices and learn how to implement them with Scala and Lagom framework.

Professional Scala

This book teaches you how to build and contribute to Scala programs, recognizing common patterns and techniques used with the language. You'll learn how to write concise, functional code with Scala. After an introduction to core concepts, syntax, and writing example applications with scalac, you'll learn about the Scala Collections API and how the language handles type safety via static types out-of-the-box. You'll then learn about advanced functional programming patterns, and how you can write your own Domain Specific Languages (DSLs). By the end of the book, you'll be equipped with the skills you need to successfully build smart, efficient applications in Scala that can be compiled to the JVM.
