AI BriefingImproving Code Quality - Session 68: Tests Can Be a Double-Edged Sword
Key point
Injecting excessive logic for the sake of testing can make tests complex and risks missing verification of actual interactions.
Details
FooModelLogger plays the role of decorating FooModel's string properties to improve log readability. In the implementation, it is designed so that dependent logic can be injected via constructor arguments, allowing unit tests to focus solely on the internal logic of FooModelLogger.
However, excessive use of Dependency Injection for testing purposes can make the test code complex. This can ultimately become a cause for failing to properly verify the actual Interaction between objects.
