Mockito - returning the same object as passed into method

Question

Let\'s imagine I have a following method in some service class:

public SomeEntity makeSthWithEntity(someArgs){
    SomeEntity entity = new SomeEntity();
    /**
         


        

Answer 1

You can implement an Answer and then use thenAnswer() instead.

Something similar to:

when(mock.someMethod(anyString())).thenAnswer(new Answer() {
    public Object answer(InvocationOnMock invocation) {
        return invocation.getArguments()[0];
    }
});

Of course, once you have this you can refactor the answer into a reusable answer called ReturnFirstArgument or similar.
