Junit: java.lang.IllegalStateException: не удалось загрузить ApplicationContext

Question

Я пытаюсь запустить тест Junit для проверки уровня сервиса.Я использую Spring 4, Hibernate 5.2.3 и JUnit 4.12.Я не знаю, почему я получаю это исключение при выполнении тестового кода. Я испробовал все возможные способы выполнения кода, но мне не удалось запустить тестовые случаи.

Класс тестаниже-

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/applicationContext.xml" })

    @Test
    public void testGetAge() {

        int age = HelperClass.getAge(Utiity.getCurrentDate());
        assertEquals(0, age);
