unit-testing - 如何模拟已声明的私有(private)字段？

Question

我将如何 mock Person？

class Test {
    private Person person;
    ...
    public void testMethod() {
        person.someMethod();
        ...
    }
}

Answer 1

一种模拟 Person 的方法，使用注释和 mockito:

public class UnitTest {

    @Mock
    private Person person;

    @InjectMocks
    private Test test = new Test();

    @Test
    public void testMethod() {
        MockitoAnnotations.initMocks(this);
        test.testMethod();
    }
}
