How to access a filed(or its getter and setter) in a RestController in Junit WebMvcTest?
问题
Here is the translated content you requested:
目前，我正在使用Junit和Mockito为Spring Boot应用程序编写单元测试。我最近遇到的问题是，我们有一个RestController类，其中包含一些字段。
其中一些字段是通过构造函数注入的，可以进行模拟。
但我有一个私有字段，只能使用setter方法进行初始化。
让我们看一下代码：
@RequestMapping("/api/directory")
public class DirectoryController {
private final DirectoryService service;
private ScheduledFuture future;
public ScheduledFuture getFuture() {
return future;
}
public void setFuture(ScheduledFuture future) {
this.future = future;
}
public DirectoryController (DirectoryService service) {
this.service = service;
}
@GetMapping(value = "/sync")
public String sync(){
if(getFuture() == null) throw new RuntimeException();
// 进行一些工作
}
}
在这里，“ScheduledFuture future”应该使用其setter方法进行初始化。
现在，我无法为这个类中的sync()编写适当的WebMvcTest（在其中使用future字段）。因为future为空，除非我以某种方式初始化它，否则该方法将引发异常。
但我不知道该怎么做。
任何帮助将不胜感激。

Currently I'm writing unit tests for a spring boot application using Junit and Mockito. The problem I've encountered recently is that we have a RestController class which has some fields.
some of the fields are injected thorough Constructor and can be mocked.
but I have a private field which is not initialize using constructor and can be initialize only using setter method.
let's have a look at the code :
@RequestMapping("/api/directory")
public class DirectoryController {
private final DirectoryService service;
private ScheduledFuture future;
public ScheduledFuture getFuture() {
return future;
}
public void setFuture(ScheduledFuture future) {
this.future = future;
}
public DirectoryController (DirectoryService service) {
this.service = service;
}
@GetMapping(value = "/sync")
public String sync(){
if(getFuture() == null) throw new RuntimeException();
// do some work
}
}
Here "ScheduledFuture future" should be initilize using its setter method.
Now, I Cannot write a proper WebMvcTest for a sync() in this class(in which we use future field). because future is null and the method will throw an exception unless I initilize it somehow.
but I don't know how to do that.
Any help will be appreciated.

什么都不会阻止你手动调用setter方法。
让我们假设你有以下测试代码：
@WebMvcTest(DirectoryController.class)
class YourTest{
@Autowired
private MockMvc mockMvc;
@Test
void testSync() throws Exception{
mockMvc
.perform(get("/api/directory/sync"))
.andExpect(status().isOk());
//一些其他检查
}
}
你可以只需自动装配控制器，创建你的模拟对象，然后在发出请求之前调用setter方法：
@WebMvcTest(DirectoryController.class)
class YourTest{
@Autowired
private MockMvc mockMvc;
@Autowired
private DirectoryController directoryController;//控制器已自动装配
@Test
void testSync() throws Exception{
ScheduledFuture future = createYourMockObject();
directoryController.setFuture(future);//这里
mockMvc
.perform(get("/api/directory/sync"))
.andExpect(status().isOk());
//一些其他检查
}
}
英文:
Nothing stops you from calling the setter manually.
Let's assume you have a test like the following:
@WebMvcTest(DirectoryController.class)
class YourTest{
@Autowired
private MockMvc mockMvc;
@Test
void testSync() throws Exception{
mockMvc
.perform(get("/api/directory/sync"))
.andExpect(status().isOK());
//some other checks
}
}
You can just autowire the controller, create your mock object and then call the setter before making the request:
@WebMvcTest(DirectoryController.class)
class YourTest{
@Autowired
private MockMvc mockMvc;
@Autowired
private DirectoryController directoryController;//controller is autowired
@Test
void testSync() throws Exception{
ScheduledFuture future = createYourMockObject();
directoryController.setFuture(future);//HERE
mockMvc
.perform(get("/api/directory/sync"))
.andExpect(status().isOK());
//some other checks
}
}
