Load dependency in webmvctest
问题
以下是翻译好的部分：
我有一个Rest控制器，我正在尝试进行单元测试：
它有一些自动装配的依赖项
@RestController
@RequestMapping("/test")
public class TestController {
private final Dep1 dep1;
private final Dep2 dep2;
private final Dep3 dep3;
public TestController(final Dep1 dep1,
final Dep2 dep2,
final Dep3 dep3) {
this.dep1 = dep1;
this.dep2 = dep2;
this.dep3 = dep3;
}
}
我最近添加了dep3
@Service
public class Dep3 {
private final IValidator validator;
public Dep3(final IValidator validator) {
this.validator= validator;
}
public void validate(final Request req) {
validator.validate(req);
}
}
Dep3有它自己的Autowired依赖IValidator
这是我的测试类：
@WebMvcTest(TestController.class)
public class TestControllerTest {
@MockBean
private Dep1 dep1;
@MockBean
private Dep2 dep2;
@MockBean
private Dep3 dep3;
@Autowired
private MockMvc mockMvc;
@Test
public void someTest() throws Exception {
}
@TestConfiguration
static class InnerConfiguration {
@Bean
IValidator validator() {
return new SomeValidator();
}
}
}
对于我的测试，我需要实际运行dep3.validate(..)，并使用实现SomeValidator()。我不确定如何实现这一点。也许我缺少一个注释？
英文:
I have a rest controller which I am trying to Unit Test:
It has a few dependencies autowired
@RestController
@RequestMapping("/test")
public class TestController {
private final Dep1 dep1;
private final Dep2 dep2;
private final Dep3 dep3;
public TestController(final Dep1 dep1,
final Dep2 dep2,
final Dep3 dep3) {
this.dep1 = dep1;
this.dep2 = dep2;
this.dep3 = dep3;
}
}
I recently added dep3
@Service
public class Dep3 {
private final IValidator validator;
public Dep3(final IValidator validator) {
this.validator= validator;
}
public void validate(final Request req) {
validator.validate(req);
}
}
Dep3 has its own Autowired Dependency IValidator
Here is my test class:
@WebMvcTest(TestController.class)
public class TestControllerTest {
@MockBean
private Dep1 dep1;
@MockBean
private Dep2 dep2;
@MockBean
private Dep3 dep3;
@Autowired
private MockMvc mockMvc;
@Test
public void someTest() throws Exception {
}
@TestConfiguration
static class InnerConfiguration {
@Bean
IValidator validator() {
return new SomeValidator();
}
}
}
For my test, I need the code to actually run the dep3.validate(..) with the implementation SomeValidator(). I am unsure how to achieve this. Perhaps I am missing an annotation?

不要模拟 Dep3。而是在 @TestConfiguration 中配置 Dep3 的 bean：
@TestConfiguration
static class InnerConfiguration {
@Bean
Dep3 dep3() {
return new Dep3(validator());
}
@Bean
IValidator validator() {
return new SomeValidator();
}
}
Spring 将会将完全配置好的 Dep3 注入到 TestController 中。
英文:
Don't mock Dep3. Instead configure Dep3 bean in @TestConfiguration:
@TestConfiguration
static class InnerConfiguration {
@Bean
Dep3 dep3() {
return new Dep3(validator());
}
@Bean
IValidator validator() {
return new SomeValidator();
}
}
Spring will inject fully configured Dep3 into TestController

你必须正确配置你的模拟。
类似这样：
Mockito.when(dep3.validate(Mockito.any(Request.class))).thenReturn(new SomeValidator());
你可以在测试方法中或在实际调用之前的设置方法中完成这个步骤。
英文:
You have to configure your Mock correctly.
Something like this:
Mockito.when(dep3.validate(Mockito.any(Request.class))).thenReturn(new SomeValidator());
You can do this in your test method or in the setup method before the actual call.
