I write function in rest to automatically generate user with admin role. Here's the function:
UserController.java
@RestController
@RequestMapping("users")
public class UserController {
@Autowired
private UserRepository userRepo;
@Autowired
private TokenRepository tokenRepo;
@GetMapping("admin")
public String getAdmin () {
JSONObject report = new JSONObject();
String dataAdmin = userRepo.findByUsername("admin");
if(dataAdmin == null) {
User myadmin = new User();
myadmin.setUsername("admin");
myadmin.setFirstname("admin");
myadmin.setLastname("admin");
myadmin.setEmail("admin@admin");
myadmin.setRole("admin");
userRepo.save(myadmin);
report.put("message", "admin generated");
} else {
report.put("message", "admin only generated once");
}
return report.toString();
}
I am trying to follow the instruction from here https://www.springboottutorial.com/unit-testing-for-spring-boot-rest-services. In Unit Testing Http Get Operation section. I am getting several problem and also trying the different solution until I meet this Unit testing a Get request in a spring project from stackoverflow. below is the testing script I've make so far.
package blablaaa.order;
import java.util.ArrayList;
import java.util.List;
import org.json.JSONObject;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.RequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import blablaaa.order.controller.UserController;
import blablaaa.order.dao.UserRepository;
import blablaaa.order.model.User;
//@ExtendWith(SpringExtension.class)
//@SpringBootTest
@WebMvcTest(value = UserController.class)
class OrderApplicationTests {
//
@Autowired
private MockMvc mockMvc;
@MockBean
private UserRepository userRepo;
@Test
void contextLoads() throws Exception{
User myadmin = new User();
myadmin.setUsername("admin");
myadmin.setFirstname("admin");
myadmin.setLastname("admin");
myadmin.setEmail("admin@admin");
myadmin.setRole("admin");
List<User> myUser = new ArrayList<>();
myUser.add(myadmin);
RequestBuilder rb = MockMvcRequestBuilders.get("/users/admin").accept(MediaType.APPLICATION_JSON);
MvcResult result = mockMvc.perform(rb).andReturn();
JSONObject expect = new JSONObject();
expect.put("message", "admin generated");
// System.out.println(result.toString());
System.out.println(expect.toString());
// Assertions.assertTrue(result.toString().contains(expect.toString()));
}
}
I dont know, how the testing should be written. any keyword related to this?
[update]
Here's my main:
// OrderApplication.java
@SpringBootApplication
@EnableMongoRepositories("blablaaa.order.dao")
public class OrderApplication {
public static void main(String[] args) {
SpringApplication.run(OrderApplication.class, args);
}
}
Here's my program error log
Description:
Field tokenRepo in blablaaa.order.controller.UserController required a bean named 'mongoTemplate' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean named 'mongoTemplate' in your configuration.
CodePudding user response:
The first thing you have to do is to clearly understand what your method getAdmin
is doing and secondly clearly identify your dependencies and how they interact in the main method.
To finish, you have to define what you want to test, in your case you have two cases. The if
case and the else
case.
In your test you must define the behavior of your mock with a when().thenReturn()...
Your test method will look like this:
@WebMvcTest(value = UserController.class)
class OrderApplicationTests {
@Autowired
private MockMvc mockMvc;
@MockBean
private UserRepository userRepo;
@Test
void contextLoads_whenNotNull() throws Exception{
User myadmin = new User();
myadmin.setUsername("admin");
myadmin.setFirstname("admin");
myadmin.setLastname("admin");
myadmin.setEmail("admin@admin");
myadmin.setRole("admin");
when(userRepo).thenReturn(myadmin)
mockMvc.perform(get("/users/admin")
.contentType(MediaType.APPLICATION_JSON))
.andExpectAll(
status().isOk(),
jsonPath("$.message", containsString("admin generated"))
);
}
@Test
void contextLoads_whenIsNull() throws Exception{
when(userRepo).thenReturn(null)
mockMvc.perform(get("/users/admin")
.contentType(MediaType.APPLICATION_JSON))
.andExpectAll(
status().isOk(),
jsonPath("$.message", containsString("admin only generated once"))
);
}
}

CodePudding user response:
previously i am laravel user. When i run unit testing, i dont need to run the apps before i can run testing scenario. So i think, the error log tell me that the mongo database is not connected to apps, even the apps itself is not running yet.
So, based on my case, i need to make sure run the apps first, not build. If i only build the apps, the program will remain error.
By default, when you need to build the apps, you need to make sure the apps is already running too. Spring Boot will also run the test case before build the jar file.
first, run the apps
mvn spring-boot:run
then,
- you can run only the test case
mvn test
- or build your apps
mvn clean package
