Testing is a fundamental part of writing software. Tests should be written with as much care as we put into designing and coding our applications. Still, writing clean and well-organized test cases can be difficult. In many cases, their quality is lower than that of the rest of the application. This can seriously impact the overall quality and maintainability of the project in the long run.

The focus of this course is on unit and integration tests in Scala. First, you’ll learn about the most famous testing framework for Scala—ScalaTest. Then, you’ll move to mocking and property-based testing with Mockito and ScalaCheck. Finally, the course will focus on integration testing, showing how to mock the dependencies on external services with Docker and TestContainers.

After taking this course, you’ll have a more comprehensive view of the possibilities to run different tests in Scala, including practical knowledge of some widespread testing libraries.
