java - 为什么 Mockito 类型匹配器匹配不相关的对象？

Question

我需要一个依赖于参数类型的模拟行为。我试过使用 Matchers.any(Class<>)提供两种行为:

public class MockitoTest {
    public interface ToMock {
        String accept(Object object);
    }
    interface A {
    }
    interface B {
    }
    @Test
    public void doAnswer() {
        ToMock mock = Mockito.mock(ToMock.class);

        Mockito.doReturn("A received").when(mock).accept(Matchers.any(A.class));
        Mockito.doReturn("B received").when(mock).accept(Matchers.any(B.class));

        Assert.assertEquals("A received", mock.accept(new A() {}));
        Assert.assertEquals("B received", mock.accept(new B() {}));
    }
}

测试失败:

org.junit.ComparisonFailure: expected:<[A] received> but was:<[B] received>

我做错了什么？

Mockito 版本 1.9.5

这是预期的行为。根据 Matchers.any(Class) 的文档

Any kind object, not necessary of the given class. The class argument is provided only to avoid casting.
