Difference between @Mock and @InjectMocks

In the context of testing with the Mockito framework, the @Mock annotation is used to create a mock object of a class or interface, and the @InjectMocks annotation is used to inject the mock objects into a test class.

Here is an example of how you can use the @Mock and @InjectMocks annotations in a test class:

@Mock
private MyClass myClass;

@InjectMocks
private MyTestClass myTestClass;

@Before
public void setup() {
    MockitoAnnotations.initMocks(this);
}

In this example, the @Mock annotation is used to create a mock object of the MyClass class. The @InjectMocks annotation is used to create an instance of the MyTestClass class and inject the mock object of the MyClass class into it.

The setup() method initializes the mock objects with the MockitoAnnotations.initMocks() method.

The @Mock annotation is used to create mock objects that can be used to replace dependencies in a test class. The @InjectMocks annotation is used to create an instance of a class and inject the mock objects into it, allowing you to test the behavior of the class.

I hope this helps! Let me know if you have any questions.
