What's wrong with the test?

[tangara goh]

Hi experts,

Not sure if I am in the right direction but I am creating a mock test, since I am still not able to get anything out of my end point.

So, here it goes:

package com.petstore.test;

import static org.hamcrest.CoreMatchers.any;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.runner.RunWith;
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.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.petstore.controller.PetController;
import com.petstore.model.Pet;
import com.petstore.service.PetService;

@RunWith(SpringRunner.class)
@WebMvcTest(PetController.class)
public class petControllerTest {
	
	@MockBean
	PetService petService;
	
//	ObjectMapper mapper = new ObjectMapper();
	
	@Autowired
	private MockMvc mockMvc;
	
	
	public void it_should_return_created_user() throws Exception{
		Pet pet = new Pet();
		pet.setName("milo");
		
			
		when(petService.save((Pet) any(Pet.class))).thenReturn(pet);
		mockMvc.perform(post("/pets")
		
		.andExpect(ResultMatcher) (((ResultActions) content().contentType(MediaType.APPLICATION_JSON)
		.andExpect(status().isOk()))
		.andExpect(ResultMatcher)(jsonPath(String.valueOf(pet.getName())));
		
		
	}
	
}

The error is please see attached.

Please let me know how to resolve the error cos I feel the code is something wrong.

Hi,
Try not to type cast :

  when(petService.save(any(Pet.class))).thenReturn(pet);
        mockMvc.perform(post("/pets")
        .andExpect(content().contentType(MediaType.APPLICATION_JSON)
        .andExpect(status().isOk()))
        .andExpect(jsonPath(String.valueOf(pet.getName())));

Hi,
Also, since you are posting a pet,

when(petService.save(any(Pet.class))).thenReturn(pet);
       String jsonInput = "{ ....}"  // put your pet in Json format
       mockMvc.perform(post("/pets")
                                .contentType(MediaType.APPLICATION_JSON)
                                .content(jsonInput)
                                 )
     
       .andExpect(status().isOk()))
       //suppose your json has name attribute and the pet is called Milo
       .andExpect(jsonPath("$.name", is ("Milo"));
