Course details
The beauty of test-driven development is that it allows you to iterate your codebase one step at a time, testing and reworking individual cases as you go. Not only does this reduce the likelihood of bugs and errors, it also helps you write more effective and more reliable code.
In this course, instructor Bethan Palmer covers the essentials of unit testing in Java to showcase the benefits of test-driven development. Explore practical topics including common assertions, comparing arrays, and testing exceptions as well as some of the more advanced features of JUnit, the Java unit testing framework that lets you run parameterized tests. Along the way, take advantage of the opportunity to practice writing your own unit tests with hands-on, interactive coding exercises in GitHub Codespaces.
