java - Mockito 局部变量

Question

我正在将mockito与spring(java 1.8)一起使用，并且我尝试在我的Answer对象中使用局部变量:

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;
}

但我收到此错误:

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"));

Answer 1

该错误与您的答案无关。它是从这一行生成的:

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

并且，正如错误所解释的“如果匹配器与原始值组合，则可能会发生此异常”。要解决此问题，您需要使用 Matcher 而不是 ProductDTO.class 值。 eq应该符合要求:

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