Reviews

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 logic flaws early. You’ll also learn how SOLID principles and hexagonal architecture create well-engineered, testable code and how test doubles manage external dependencies. Finally, you’ll integrate the sample application’s domain logic with the database and web layers. By the end of this course, you’ll have mastered testing complexities and learned to integrate code with external systems with a deep understanding of practical techniques to elevate your development practices.
