Spring JSF2.0托管/支持bean的Junit测试用例

我是JUnit新手，我已经为服务层（业务层）和数据库层（Hibernate层）编写了测试用例。当我为BackingBean写作时，我遇到了一个无法解决的错误。看看附件中的片段，帮助我摆脱这种沮丧

Test.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={
"file:src/main/resources/config/spring/beans/HibernateSessionFactory.xml",
    "file:src/main/resources/config/spring/beans/DataSourceTest.xml",
"file:src/main/resources/com/dynaprice/customer/spring/CustomerBean.xml"})
public class RepricingBeanTest {

RepricingBean beanrep;

@Test
public void testHello() {
    String strTest = beanrep.test();
    assertEquals("Hello", strTest);;
}
}

RepricingBean.java中的方法

public String test(){
    return "Hello";
}

我收到的错误
