Spring Boot Controller Test, Null Pointer Exception

I'm learning to makes APIs. I'm trying to run a test on my Get request, but keep getting a Null Pointer Exception in my test class. What did I miss?
I'm using Spring Boot/Maven/Java 11. This is a very basic setup (as far as I know) as I have just begun to dip my toe into the world of Spring Boot.
Please see code below:
Controller Test Class:
package ControllerTest;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultMatcher;
import org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
public class StatControllerTest {
#Autowired
private MockMvc mockMvc;
#Test
public void testGetResponse()
throws Exception {
MockHttpServletRequestBuilder builder = MockMvcRequestBuilders
.get("/get");
ResultMatcher contentMatcher = MockMvcResultMatchers.content()
.string("GET Response");
mockMvc.perform(builder).andExpect(contentMatcher).andExpect(MockMvcResultMatchers.status().isOk());
}
}
Controller Class:
package apiPackage;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
#RestController
public class StatController {
#RequestMapping("/")
public String index(){
return "Welcome to the SilverSnacks Stat Sheet!";
}
#GetMapping("/get")
public #ResponseBody ResponseEntity<String> get(){
return new ResponseEntity<String>("GET Response", HttpStatus.OK);
}
#GetMapping("/get/{id}")
public #ResponseBody ResponseEntity<String> getById(#PathVariable String id){
return new ResponseEntity<String>("GET Response:" + id, HttpStatus.OK);
}
#PutMapping("/put")
public #ResponseBody ResponseEntity<String> put(){
return new ResponseEntity<String>("PUT Response", HttpStatus.OK);
}
#PostMapping("/post")
public #ResponseBody ResponseEntity<String> post(){
return new ResponseEntity<String>("POST Response", HttpStatus.OK);
}
#DeleteMapping("/delete")
public #ResponseBody ResponseEntity<String> delete(){
return new ResponseEntity<String>("DELETE Response", HttpStatus.OK);
}
#PatchMapping("/patch")

}
}

From the stack trace, it seems it fails because you didn't mock also the user repository.
Add the following:
#Mock
UserRepository userRepository;
...
when(userRepository.doesAccountExistsWithGivenID(user.getId()).thenReturn(true);

How to solve internal error from server (test)?

guys. I'm testing method and in test it's name is testGetAuthorizedUserPublicInfo. This method have to return an User object. (So i created getUser method which return our new user).
Then after calling some methods on mockMvc objects try to perform get method (url is the same like in Controller class).
But i getting 500 response (instead of 200).
Can anyone say where is my mistake?? it would be really great )

Have you tried annotating your test class to use the SpringRunner unit test harness?
#RunWith(SpringRunner.class)
class UltraServiceTest {
}
