How to mock default method of unimplemented interface?
问题
I can provide the translation of the code-related content:
在进行Junit/Mockito/PowerMockito的实际操作时，我有一个接口类：
import retrofit2.Call;
import com.learning.model.user.User;
import java.io.IOException;
public interface UserService {
@GET("/serviceUser/{userId}")
Call<User> getUser(@Path("userId") String userId);
default User getUserById(String userId) {
try {
return getUser(userId).execute().body();
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
static UserService getUserService() {
//设置Retrofit...
}
}
在另一个服务类中：
public class DemoUser {
public void doUserBusiness(String userId) {
User user = UserService.getService().getUserById(userId);
//在这里执行业务逻辑
}
}
然后，您如何在测试doUserBusiness方法时模拟UserService.getService().getUserById(userId);以返回一个模拟用户呢？

I'm doing some hands on with Junit/Mockito/PowerMockito
I have an interface class
import retrofit2.Call;
import com.learning.model.user.User;
import java.io.IOException;
public interface UserService {
@GET("/serviceUser/{userId}")
Call<User> getUser(@Path("userId") String userId);
default User getUserById(String userId) {
try {
return getUser(userId).execute().body();
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
static UserService getUserService(){
//setup retrofit ...
}
}
In another service:
public class DemoUser {
public void doUserBusiness(String userId) {
User user = UserService.getService().getUserById(userId);
//do business logic here
}
}
Then how can I mock the UserService.getService().getUserById(userId); to return a mock user when testing the doUserBussiness method?

你可以尝试使用 mockStatic()，示例代码如下：
try (MockedStatic<UserService> serviceMockedStatic = mockStatic(UserService.class)) {
serviceMockedStatic
.when(() -> UserService.getService().getUserById(userId))
.thenReturn(any());
}
更多信息请查看这里：staticMock
英文:
You can try to use mockStatic() like:
try (MockedStatic<UserService> serviceMockedStatic = mockStatic(UserService.class)) {
serviceMockedStatic
.when(() -> UserService.getService().getUserById(userId))
.thenReturn(any());
}
