Android 使用模拟对象

我刚刚用Mockito在Android上开始了单元测试-如何让正在测试的类使用模拟类/对象而不是常规类/对象？

通过注入依赖项：

public class ClassUnderTest
    private Dependency dependency;

    public ClassUnderTest(Dependency dependency) {
        this.dependency = dependency;
    }

    // ...
}

...

 Dependency mockDependency = mock(Dependency.class);
 ClassUnderTest c = new ClassUnderTest(mockDependency);

您还可以使用setter注入依赖项，甚至可以使用

@Mock

和

@InjectMocks

注释直接注入私有字段（阅读以了解它们如何工作的详细说明）

您可以对编写测试的类使用@InjectMocks

@InjectMocks
私人雇员经理

然后可以对正在模拟的类使用@Mock。这将是依赖类

@Mock
私人就业服务

然后编写一个设置方法，使测试可用

然后写下你的测试

@Test
public void testSaveEmploy() throws Exception {
    Employ employ = new Employ("u1");
    manager.saveEmploy(employ);

    // Verify if saveEmploy was invoked on service with given 'Employ'
    // object.
    verify(service).saveEmploy(employ);

    // Verify with Argument Matcher
    verify(service).saveEmploy(Mockito.any(Employ.class));
}

---

你能给我一个答案吗。谢谢

@Test
public void testSaveEmploy() throws Exception {
    Employ employ = new Employ("u1");
    manager.saveEmploy(employ);

    // Verify if saveEmploy was invoked on service with given 'Employ'
    // object.
    verify(service).saveEmploy(employ);

    // Verify with Argument Matcher
    verify(service).saveEmploy(Mockito.any(Employ.class));
}
