Question

我想在spring应用程序中测试一个函数。这是项目

的结构

这是我要测试的服务类

公共类DepartmentServiceImpl实现DepartmentService {

@Autowired
private DepartmentDao departmentDao;
//... other functions 

@Override
public Department getDepartment(int depid) {
    return departmentDao.getDepartment(depid);
   }
}

这是我制作的测试单元类

@RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(locations = "sdnext-servlet.xml")
  public class TestDepartmentDetails {

Department department  = new Department();
DepartmentServiceImpl service = new DepartmentServiceImpl();

@Autowired
private DepartmentDao myDao;


@Test
public void testGetDepartment(){
    assertEquals("lalalalalalala", service.getDepartment(98).getDepName());
    }
  }

但发生了

的例外情况

Answer 1

您的测试类未在Web服务器中运行。这就是为什么你在CLASSPATH中找不到WEB-INF的原因。您需要使用绝对文件路径。

你能试试吗

@ContextConfiguration("file:WebContent/WEB-INF/config/sdnext-servlet.xml")

Answer 2

通常当您需要进行单元测试时，配置文件和资源应该与部署文件分开。因此，您需要拥有配置文件sdnext-servlet.xml的副本或另一个定义资源和数据库配置以进行测试的副本。将此文件放在测试类目录的同一目录中。在您的情况下，您只需要编写数据库和Dao配置。
