Simple WebMvcTest fails with Spring Boot Missing SpringBootConfiguration

Question

Test 1

package test.java.rest.springframework.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringBootWebTest {

    @Test
    public void contextLoads() {
    }

   }

Test 2

package test.java.rest.springframework.test;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

public class TestWebApp extends SpringBootWebTest {

@Autowired
private WebApplicationContext webApplicationContext;

private MockMvc mockMvc;

@Before
public void setup() {
    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}

@Test

    mockMvc.perform(get("/")).andExpect(status().isOk())
            .andExpect(content().contentType("application/json;charset=UTF-8"));

I am trying to do a simple junit test for my mvc controller index page. I followed Tutorial link But I am getting a missing springbootconfiguarion error? How can I create simple JUnit test with spring boot.

In what package is your main class that's annotated with `@SpringBootApplication`? — Andy Wilkinson, Feb 17 '17 at 22:21
Answer is in your error only. you have to mention configuration in SpringBootTest. `@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK)` Try this. Also you can auto configure MockMvc with `@AutoConfigureMockMvc` — Vijendra Kumar Kulhade, Feb 18 '17 at 02:52

Annotate your test class with @ContextConfigurationas below.

@ContextConfiguration(classes = {TestBeanConfig.class})

An empty annotation

@SpringBootTest

is not enough. You need to declare the configuration classes the test should use. You can do it like this :

@SpringBootTest(classes = { MyConfig1.class,MyConfig2.class })

I am not sure, if annotating the test super class works, so you may try to annotate the test class 'TestWebApp' directly.
