ScalaTest is a popular choice to test Scala projects. It has been used by well-known open-source projects such as Akka. In this course, Unit Testing in Scala, you will learn how to test a Scala project using ScalaTest. First, you will test your codebase using Assertions and Matchers. Next, you will discover how to create Fixtures for your testing using various methods, and how to test for asynchronous code. Then, you will see how to mock complex object creation and test for behaviors, while also learning to create tags and apply them selectively to your tests so that you can run tests based on the tags. Finally, you will explore different ways of running a test written using ScalaTest library. When you are finished with this course, you will have all the required knowledge to plug ScalaTest into your projects and start testing with confidence.
