You have code that makes use of dependency injection at all times. Can you tell me if this code will be easy to test?

A DI is a software engineering pattern where a child/bean is constructed and all the necessary dependencies are provided by the parent class.When it comes to testing DI is not always the best thing.DI is almost based on abstractions and we do not run our tests on abstractions.Moreover testing is done on discrete implementation of a program.Morever if testing is required in DI code we need to create another class which uses the reusable or making it dependable to other class which provides all dependencies and calling them by test methods which is okay but we still are creating another class in which one is the discrete implementation and calling both which in turn making it duplication of code.
