Failed to load ApplicationContext for Junit test and Spring

I want to test my service using JUnit,I am getting some error like Failed to load ApplicationContext I tried to load spring configuration class using @ContextConfiguration(loader = AnnotationConfigWebContextLoader.class, classes={MvcConfiguration.class}).I kept bussiness classes and spring configuration class in src/main/java folder and my test classes in src/test/java folder even i tried to put MvcConfiguration class in src/test/java folder as well but it didn't work out shows same problem again

This is my test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigWebContextLoader.class, 
classes={MvcConfiguration.class})
public class ServiceTest {
    @Autowired
   private EmployeeService empService;
    @Test
    public void test() {
        assertEquals(21, empService.employeeCount());
    }
    @BeforeClass
    public static void serviceIntaciation(){
        System.out.println("beforeclass");
    }

}
