Mockito local variable

I am using mockito with spring (java 1.8) and I am trying to use a local variable inside my Answer object:

public IProductDTO productForMock = null;


@Bean
@Primary
public ICouchbaseDTOProvider mockCreateProductDelegate() {

    CouchbaseDTOProvider mockService = mock(CouchbaseDTOProvider.class);

    Mockito.when(mockService.get(anyString(), ProductDTO.class)).thenReturn((IBaseCouchbaseDTO) productForMock);

    Mockito.when(mockService.getEnvironment()).thenReturn(null);

    Mockito.when(mockService.insert((IBaseCouchbaseDTO) anyObject())).thenAnswer(
            new Answer<IProductDTO>() {
                @Override
                public IProductDTO answer(InvocationOnMock invocation) throws Throwable {
                    productForMock = invocation.getArgumentAt(0, IProductDTO.class);
                    return null;
                }
            }

    );

    return mockService;
}

But I am getting this error:

This exception may occur if matchers are combined with raw values:
    //incorrect:
    someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
    //correct:
    someMethod(anyObject(), eq("String by matcher"));

The error has nothing to do with your Answer. It's generated from this line:

Mockito.when(mockService.get(anyString(), ProductDTO.class))
       .thenReturn((IBaseCouchbaseDTO) productForMock);

And, as the error explains "This exception may occur if matchers are combined with raw values". To solve this you need to use a Matcher instead of the ProductDTO.class value. eq should fit the bill:

Mockito.when(mockService.get(anyString(), eq(ProductDTO.class)))
        // Here --------------------------^
       .thenReturn((IBaseCouchbaseDTO) productForMock);

The error This exception may occur if matchers are combined with raw values: means:

You can have an expectation containing raw values:

 Mockito.when(mockMixer.mix("red","white")).thenReturn("pink");

... or you can have an expectation containing matchers:

 Mockito.when(mockMixer.mix(startsWith("re"), endsWith("ite")).thenReturn("pink"));

... but you can't have a mixture of both:

 // Compiles, but will cause runtime exception
 Mockito.when(mockMixer.mix(startsWith("re"), "white").thenReturn("pink"));

The fix is to replace the raw value with eq("white") -- now you're passing a matcher that looks for parameters equal to "white".
