It’s a problem almost every developer will face in their career: inheriting an essential legacy library that’s full of bugs and has no automated tests to keep it running smoothly. In this liveProject series, you’ll step into the shoes of a Java developer handling just such a codebase for a stock image web application—one that will soon require significant changes to the library you maintain.

You’ll use JUnit 5 and IntelliJ IDEA to write tests and refactor this buggy code into something both usable and indefinitely maintainable. Each project is focused on a different approach or testing methodology to let you pick and choose which testing techniques to add to your toolbox.
