Course Overview

In this course we are going to have a detailed look at how to write unit and integration tests for a Java and Spring application, starting from the most basic examples and reaching the most complex integration test cases possible within a Spring application. In order to better understand the practical value of unit and integration tests we will use a fully functional Spring project, for which we will take each comprising part and do full unit test coverage making sure we cover all relevant test cases. While writing our unit tests we will also get into specific details on how to establish, create and manage our tests data in order to adhere to Java development principles and practices, which ensure highest level of re-usability and flexibility for our tests.

  • Understand how to design and implement unit tests.
