功能代码按照Spring的标准书写,无论是通过XML配置还是通过annotation配置都可以。
测试代码最重要的是告诉framework去哪里找bean的配置。
以Dao的Test为例:
- //告诉framework怎么运行这个类
- @RunWith(SpringJUnit4ClassRunner.class)
- //bean的配置文件路径,这个是Test类的classpath路径,如果是Spring推荐的目录结构,应该在:项目目录/src/test/resources/里
- @ContextConfiguration(locations = "classpath:app-config.xml")
- public class TestPatchDao extends AbstractTransactionalJUnit4SpringContextTests {
- //取得要测试的Dao类
- @Resource
- private PatchDao patchDao;
-
- @Before
- public void setUp() throws Exception {
- }
-
- @After
- public void tearDown() throws Exception {
- }
-
- /**
- * 测试方法
- */
- @Test
- public void testGetPatchList_1() {
- //Dao的某个方法
- List<Map<String, Object>> list = patchDao.getPatchList(1, "00C8002D00000000", 1);
- assertEquals(1, list.size());
- }
- }
再举一个Controller的例子
- @RunWith(SpringJUnit4ClassRunner.class)
- @ContextConfiguration(locations = {"classpath:app-config.xml", "classpath:mvc-config.xml"})
- public class TestMainCtrl extends AbstractTransactionalJUnit4SpringContextTests {
- @Autowired
- private MainCtrl controller;
-
- //这种方法适用于Springframework3.0,3.1换了handler的处理类。
- @Autowired
- private AnnotationMethodHandlerAdapter handlerAdapter;
-
- private final MockHttpServletRequest request = new MockHttpServletRequest();
- private final MockHttpServletResponse response = new MockHttpServletResponse();
-
- @Test
- public void testMain4User() throws Exception {
- request.setRequestURI("/main");
- request.setMethod(HttpMethod.POST.name());
- HttpSession session = request.getSession();
- //设置 认证信息
- session.setAttribute(CommonConstants.SESSION_USER_TYPE, 1);
- session.setAttribute(CommonConstants.SESSION_USER_ID, 0);
- session.setAttribute(CommonConstants.SESSION_USER_ACC, "aa1");
-
- ModelAndView mav = handlerAdapter.handle(request, response, controller);
- assertEquals("/regist", mav.getViewName());
- }
- }
TestSuite的写法,将Test类用注解的方式配置到TestSuite类上。
- import org.junit.runner.RunWith;
- import org.junit.runners.Suite;
- import org.junit.runners.Suite.SuiteClasses;
-
- @RunWith(Suite.class)
- @SuiteClasses( { TestPatchDao.class, TestMainCtrl.class })
- public class TestSuite {}
这个工具的功能都很实用,它还可以自动生成测试代码。测试代码以独立的项目存在,可以根据功能代码的流程分支生成的测试方法,比如功能代码里有一个if else,测试代码就会生成3个测试方法,以便每个分支都能覆盖到。
我们主要使用它的代码覆盖率功能,这个工具不但可以统计测试时的代码覆盖率,还可以统计debug时的覆盖率。
1、按照安装说明,将工具安装进Eclipse
2、右键点击项目,选择CodePro Tools --> Instrument for Code Coverage。
再运行测试类或debug,都会出覆盖率的统计。
但是统计覆盖率会降低代码运行效率,所以,不需要统计时再 Unistrument 就可以了。

Springframework3.1和springsecure的controller测试类例子:
- @RunWith(SpringJUnit4ClassRunner.class)
- @ContextConfiguration(locations = {"classpath:root-context.xml",
- "classpath:servlet-context.xml", "classpath:security-app-context.xml"})
- public class TestSecureCtrl extends AbstractTransactionalJUnit4SpringContextTests {
- @Autowired
- private SecureCtrl controller;
- @Autowired
- private RequestMappingHandlerAdapter handlerAdapter;
-
- private final MockHttpServletRequest request = new MockHttpServletRequest();
- private final MockHttpServletResponse response = new MockHttpServletResponse();
-
- @Test
- public void testMain4User() throws Exception {
- request.setRequestURI("/secure");
- request.setMethod(HttpMethod.POST.name());
- HttpSession session = request.getSession();
-
- //设置springsecure的内容
- List<GrantedAuthority> ga = new ArrayList<GrantedAuthority>();
- ga.add(new GrantedAuthorityImpl("ROLE_ALL"));
- User user = new User("account", "password", true, true, true, true, ga);
- SecurityContextHolder.getContext().setAuthentication(
- new UsernamePasswordAuthenticationToken(user, null));
- session.setAttribute(HttpSessionSecurityContextRepository.SPRING_SECURITY_CONTEXT_KEY, SecurityContextHolder.getContext());
-
- ModelAndView mav = handlerAdapter.handle(request, response, new HandlerMethod(controller, "home", Model.class, HttpServletRequest.class));
-
- assertEquals("home", mav.getViewName());
- }
- }
