WebNov 15, 2024 · Dependency injection approaches try to kick this configuration problem upstairs; whereas, what you're doing requires separate classes for test and development that duplicates the construction approach (of the specific sub-types) from (common) arguments. You can introduce interfaces to break the dependencies between higher and lower level classes. If you do that, both classes depend on the interface and no longer on each other. I explained this approach in great details in my article about the dependency inversion principle. That principle improves the … See more Dependency injection is a programming technique that makes a class independent of its dependencies. It achieves that by decoupling the usage of an object from its creation. This helps you to follow SOLID’s dependency inversion … See more I used the CoffeeApp example in my article about the dependency inversion principle.
