功能程式碼按照Spring的標準書寫，無論是透過XML配置還是透過annotation配置都可以。

測試程式碼最重要的是告訴framework去哪裡找bean的配置。

以Dao的Test為例：

Java程式碼 //告訴framework怎麼執行這個類 @RunWith(SpringJUnit4ClassRunner.class) //bean的配置檔案路徑，這個是Test類的classpath路徑，如果是Spring推薦的目錄結構，應該在：專案目錄/src/test/resources/裡 @ContextConfiguration(locations = "classpath:app-config.xml") public class TestPatchDao extends AbstractTransactionalJUnit4SpringContextTests { //取得要測試的Dao類 @Resource private PatchDao patchDao; @Before public void setUp() throws Exception { } @After public void tearDown() throws Exception { } /** * 測試方法 */ @Test public void testGetPatchList_1() { //Dao的某個方法 List<Map<String, Object>> list = patchDao.getPatchList(1, "00C8002D00000000", 1); assertEquals(1, list.size()); } }

再舉一個Controller的例子

Java程式碼 @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:app-config.xml", "classpath:mvc-config.xml"}) public class TestMainCtrl extends AbstractTransactionalJUnit4SpringContextTests { @Autowired private MainCtrl controller; //這種方法適用於Springframework3.0，3.1換了handler的處理類。 @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(); //設定 認證資訊 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的寫法，將Test類用註解的方式配置到TestSuite類上。Java程式碼 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 {} 統計覆蓋率。單元測試的標準往往是程式碼附帶率，發現比較好的工具是CodePro Analytix，它是google收購的一個專案，專案主頁：https://developers.google.com/java-dev-tools/codepro/doc/這個工具的功能都很實用，它還可以自動生成測試程式碼。測試程式碼以獨立的專案存在，可以根據功能程式碼的流程分支生成的測試方法，比如功能程式碼裡有一個if else，測試程式碼就會生成3個測試方法，以便每個分支都能覆蓋到。我們主要使用它的程式碼覆蓋率功能，這個工具不但可以統計測試時的程式碼覆蓋率，還可以統計debug時的覆蓋率。1、按照安裝說明，將工具安裝進Eclipse2、右鍵點選專案，選擇CodePro Tools --> Instrument for Code Coverage。再執行測試類或debug，都會出覆蓋率的統計。但是統計覆蓋率會降低程式碼執行效率，所以，不需要統計時再 Unistrument 就可以了。---------------------------------------------Springframework3.1和springsecure的controller測試類例子：Java程式碼 @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(); //設定springsecure的內容 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()); } }
