Course Overview

Test-driven development (TDD) and hexagonal architecture enable developers to engineer code that is known to work and easy to work with. The techniques described in this course enable code to be delivered to production with few defects and a structure that can be easily and safely changed. You’ll begin by learning the importance of test-driven development (TDD) and its costs and benefits, with examples of bad code and its impact on team performance. You’ll learn how good code and TDD can uncover design and...Show More
