TDD Design Starter Kit - Dependency Inversion Principle (codebetter.com)

submitted by schalkvanwykschalkvanwyk(1335) 3 years, 2 months ago

In the last episode of the TDD Design Starter Kit, I talked about the need to build cohesive classes, and make the relationships between classes loosely coupled. The specific benefit for TDD is to truly isolate the functionality of a class under the microscope of a unit test. But we've done all we can to isolate our classes, and we still have some interaction with dependencies.
