What's the difference between mockito.mock and @ mock?


Asked by Penny Carson on Dec 08, 2021 FAQ



The @Mock annotation is alternative to Mockito.mock (classToMock). They both achieve the same result. Using @Mock is usually considered “ cleaner “, as we don’t fill up the tests with boilerplate assignments that all look the same. allows shorthand creation of objects required for testing.
In addition,
The Mockito.mock () method allows us to create a mock object of a class or an interface. Then, we can use the mock to stub return values for its methods and verify if they were called. Let's look at an example:
Thereof, In mockito based junit tests, @Mock annotation creates mocks and @InjectMocks creates class objects. @Mock – creates mocks @InjectMocks – creates objects and inject mocked dependencies Use @InjectMocks to create class instances which needs to be tested in test class.
Moreover,
On EasyMock / Mockito: mainly "two different ways" of writing down test cases; the later one leading to tests that many people find easier to read; whereas EasyMock and "strict" mocks allow for writing down test cases that will break quickly upon most changes in your production code (which by itself can be very useful, or very annoying).
In this manner,
Difference between @Mock and @Spy. When using @Mock, mockito creates a bare-bones shell instance of the Class, entirely instrumented to track interactions with it. This is not a real object and does not maintain the state changes to it. When using @Spy, mockito creates a real instance of the class and track every interactions with it.
