Look inside
In this liveProject, you’ll find and fix some long-term bugs in a legacy library. You’ll write a test to characterize a bug in how certain assets are selected for a special display, then modify the test to turn it into a bugfix. Once you’ve squashed that bug, you’ll repeat the process to tackle two more common bugs for Java applications.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
