Look inside
In this liveProject, you’ll refactor poorly written legacy code in a way that lets you make changes without fear of bugs. You’ll fix the internal structure of your code, make sure code functions according to your needs with integration tests, and make in-depth changes supported by your testing suite. Finally, you’ll develop new features inside code without major changes, and replace dependencies with mock objects to help test previously unmaintainable code.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
