Spring Boot integeration test, but unable to @Autowired MockMvc
P.S Tested with Spring Boot 2.1.2.RELEASE
BookControllerTest.java
package com.mkyong;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.security.test.context.support.WithMockUser;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import static org.hamcrest.Matchers.is;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class BookControllerTest {
@Autowired
private MockMvc mockMvc; //null?
@Test
public void findOne() throws Exception {
mockMvc.perform(get("/books/1"))
.andDo(print())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8))
.andExpect(status().isOk())
.andExpect(jsonPath("$.id", is(1)));
}
}
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'org.springframework.test.web.servlet.MockMvc' available:
expected at least 1 bean which qualifies as autowire candidate.

Solution
Add this @AutoConfigureMockMvc to enable and configure auto-configuration of MockMvc
package com.mkyong;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.security.test.context.support.WithMockUser;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import static org.hamcrest.Matchers.is;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc //need this in Spring Boot test
public class BookControllerTest {
@Autowired
private MockMvc mockMvc;
@Test
public void findOne() throws Exception {
mockMvc.perform(get("/books/1"))
.andDo(print())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8))
.andExpect(status().isOk())
.andExpect(jsonPath("$.id", is(1)));
}
}
Thanks.
Thanks a lot
Forex: My API will return List<Map<Object, Object>> the how can I get the List from mockMvc response so that I can assert on required part.
How to get the response object?
Is below is the correct way?
MvcResult andReturn = mockMvc.perform(get(url)).andDo(print()).andExpect(status().isOk()).andReturn();
MockHttpServletResponse response = andReturn.getResponse();
String contentAsString = response.getContentAsString();
And also Can we get the code coverage with MockMvc?
Thanks this works! (as of Feb-2021)
