About this course

WHY I WROTE THIS COURSE

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.

These are high-quality courses. Trust me the price is worth it for the content quality. Educative came at the right time in my career. I'm understanding topics better than with any book or online video tutorial I've done. Truly made for developers. Thanks

You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it.
