Hope you have spring-boot-starter-web
dependency. Not sure which version of Spring boot you use, but build mockMvc this way instead?
@RunWith(SpringRunner.class)
@SpringBootTest
public class ApplicationTest {
@Autowired
private WebApplicationContext webApplicationContext;
private MockMvc mockMvc;
@Before
public void setUp() {
mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
