Look inside

In this liveProject, you’ll refactor the tests for a legacy e-commerce Spring application to improve readability, then add missing test coverage. You’ll use test-driven development to add a new coupon feature, organize your unit tests in a readable way that exposes missing coverage, and then fill in gaps in coverage by applying characterization testing so that the system can be changed without fear of adding bugs.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.
