Speaking from distant memory, @duluca, for the first 5-8 years of the existence of mocking libraries (over in Java-land), mocking an interface was seen as the only appropriate thing to mock, because coupling a test+subject to the contract of a dependency was seen as looser than to coupling it to any one implementation. (This coincided with interface-heavy libraries like Spring, and was also ...

So unit test isolation is not 100%. I mean no one can guarantee that the constructor of the abstract class is simple.

Use mocking framework and use a DateTimeService (Implement a small wrapper class and inject it to production code).

To get around the issue with 0 being converted to a MockBehavior (see comments and crossed out text …
This is due to the way mocking is implemented in Mockito, where a subclass of the class to be mocked is created; only instances of this "mock" subclass can have mocked behavior, so you need to have the tested code use them instead of any other instance.

DI is still possible by having the type of the dependency defined during compile-time using templates. There is still relatively tight coupling between your code and the implementation, however, since the type of the dependency can be selected externally, we can inject a mock object in our tests. struct MockMotor { MOCK_METHOD(int, getSpeed ...

In earlier chapters, we touched on various aspects of Dependency Injection (DI) and how it is used in Nest.
