TDD in Legacy Code - Get Access
You tried TDD in your real-life project, but it didn’t work. You don’t want to waste years with trial-and-error. You don’t want to read hundreds of pages of books. That’s why I made the TDD in Legacy Code series:
✔ Step-by-step guide in introducing TDD to Legacy Code
✔ Applying the TDD transformation to Legacy Microservice Architecture
✔ Ask me questions about the challenges you face applying TDD in Legacy Code
