问题描述
我试图在我的测试中模拟依赖项的依赖项.下面是我的课程的样子.
I am trying to mock a dependency of a dependency in my tests. Below is what my classes look like.
class A {
@Autowired B b;
@Autowired C c;
public String doA() {
return b.doB() + c.doC();
}
}
class C {
@Autowired D d;
public String doC() {
return d.doD();
}
}
class D {
public String doD() {
return "Hello";
}
}
我试图在调用方法 doA() 时模拟 D 类中的方法 doD()；但是，我不想模拟 B 类中的 doB() 方法.下面是我的测试用例.
I am trying to mock the method doD() in class D when calling method doA();However, I do not want to mock the doB() method in class B.Below is my test case.
@RunWith(SpringRunner.class)
@SpringBootTest(
classes = MyTestApplication.class,
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT
)
public class ATest {
@Autowired
private A a;
@InjectMocks
@Spy
private C c;
@Mock
private D d;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}
@Test
public void testDoA() {
doReturn("Ola")
.when(d)
.doD();
a.doA();
}
}
这最终仍然返回Hello"而不是Ola".我在测试类中也在 A 上尝试了 @InjectMocks.但这只会导致自动装配的 B 依赖项 B 为空.我的设置中是否缺少某些东西，或者这是解决此问题的错误方法?
This still ends up returning "Hello" instead of "Ola".I tried @InjectMocks on A as well in the test class. But that just results in the autowired B dependency B being null.Is there something that's missing with my setup or is it the wrong way to go about this?
谢谢.
推荐答案
使用 @MockBean 因为这会在执行测试方法之前将模拟 bean 注入应用程序上下文 docs.
Use @MockBean as this will inject the mock bean into the application context before executing the test method docs.
可用于向 Spring ApplicationContext 添加模拟的注解.可用作类级别注释或@Configuration 类或@RunWith SpringRunner 的测试类中的字段.
@RunWith(SpringRunner.class)
@SpringBootTest(
classes = MyTestApplication.class,
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ATest {
@Autowired
private A a;
@MockBean
private D d;
@Test
public void testDoA() {
doReturn("Ola")
.when(d)
.doD();
a.doA();
}
}
