Why do I keep getting 404's when using #AutoConfigureMockMvc in SpringBoot test? - spring-boot

Question

I'm trying to write an integration test using springrunner. I'm running it as a springboottest and using autoconfiguremockmvc. However, i keep getting 404s. It seems my controllers/endpoints aren't being loaded by the autoconfiguremockmvc. Does anyone know a solution of how to wire this up so that it will pick up my controllers?
I did add a basic controller into my test class and i was able to hit it successfully but I have been unable so far to hit the actual controller I want to use in my integration test.
#RunWith(SpringRunner.class)
#SpringBootTest(classes = { TestConfig.class })
#TestPropertySource(locations = "classpath:application-test.properties")
#AutoConfigureMockMvc
public class ControllerTest {
#Autowired
private MockMvc mockMvc;
#Test
public void test() throws Exception {
MockHttpServletRequestBuilder request =
MockMvcRequestBuilders.post(URL).contentType(MediaType.APPLICATION_JSON_UTF8_VALUE)
.accept(MediaType.APPLICATION_JSON_UTF8_VALUE)
.content(json);
final ResponseEntity<String> response =
new ResponseEntity<>("works", HttpStatus.OK);
final ResultActions result = this.mockMvc.perform(request).andDo(print());
result.andExpect(status().isOk())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE));
}
}
#TestConfiguration
#EnableAutoConfiguration
public class TestConfig {
}

You could use
#SpringBootTest(webEnvironment =
SpringBootTest.WebEnvironment.RANDOM_PORT)
and RestAssured library in combination to test any endpoint/api like below
// include dependency in pom
<dependency>
<groupId>io.rest-assured</groupId>
<artifactId>rest-assured</artifactId>
<version>3.0.5</version>
<scope>test</scope>
</dependency>
//Test Class
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class IntTest{
//inject test local port
#LocalServerPort
private int port;
#Before
public void setUp() {
//assign port for reset assured
RestAssured.port = port;
}
#Test
public void test() {
given()
.get("/api")
.then()
.assertThat()
.statusCode(HttpStatus.OK.value())
.contentType(ContentType.JSON)
.body("name", is("test"));
}
}
