介绍大家一个好的测试Spring Controller的框架
可能大家都知道了。知道的就掠过吧。
其实我想说的就是Spring原厂的Test, 文档可以参见这里:
http://static.springframework.org/spring/docs/2.5.x/reference/testing.html
我给大家一个我写的例子吧。里面有如何mock request/response, 如何往servlet context里面放从xml里面读出来的bean. 例子里面的两个文件就是Spring的bean文件。
这个框架比instinct啊, Jmock啊用起来好不少呢。测试spring+struts应该也同理。
public class SecuredControllerTest extends TestCase { private HttpServletRequest request = new MockHttpServletRequest(); private HttpServletResponse response = new MockHttpServletResponse(); private XmlWebApplicationContext context; private MockServletContext msc; private SecuredController securedController; protected void setUp() throws Exception { String[] contexts = new String[] { "tempo-ui-fw-servlet.xml", "tempo-ui-fw.xml" }; context = new XmlWebApplicationContext(); context.setConfigLocations(contexts); msc = new MockServletContext(); context.setServletContext(msc); context.refresh(); msc.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, context); } @Test public void testShowFormWithoutUser() throws Exception { securedController = (SecuredController) context.getBean("tasksController"); ModelAndView mav = securedController.showForm(request, response, null); Assert.assertTrue(mav.getView().toString().contains(Constants.LOGIN_URL)); } @Test public void testShowFormWithUser() throws Exception { FakeUIFWApplicationState state = new FakeUIFWApplicationState(); User currentUser = new User("test1", new String[] { "test/test1" }, "token1"); state.setCurrentUser(currentUser); request.getSession().setAttribute("APPLICATION_STATE", state); securedController = (SecuredController) context.getBean("tasksController"); ModelAndView mav = securedController.showForm(request, response, new BindException(currentUser, "test")); Assert.assertEquals(mav.getViewName(), "tasks"); } @Test public void testProcessFormSubmissionWithoutUser() throws Exception { securedController = (SecuredController) context.getBean("tasksController"); ModelAndView mav = securedController.processFormSubmission(request, response, null, null); Assert.assertTrue(mav.getView().toString().contains(Constants.LOGIN_URL)); } @Test public void testProcessFormSubmissionWithUser() throws Exception { FakeUIFWApplicationState state = new FakeUIFWApplicationState(); User currentUser = new User("test1", new String[] { "test/test1" }, "token1"); state.setCurrentUser(currentUser); request.getSession().setAttribute("APPLICATION_STATE", state); securedController = (SecuredController) context.getBean("tasksController"); ModelAndView mav = securedController.processFormSubmission(request, response, null, new BindException(currentUser, "test")); Assert.assertEquals(mav.getViewName(), "tasks"); } @Test public void testProcessFormSubmissionInvalidActionWithUser() throws Exception { MockHttpServletRequest mockRequest = new MockHttpServletRequest(); mockRequest.addParameter("actionName", "getTaskList"); request = mockRequest; FakeUIFWApplicationState state = new FakeUIFWApplicationState(); User currentUser = new User("test1", new String[] { "test/test1" }, "token1"); state.setCurrentUser(currentUser); request.getSession().setAttribute("APPLICATION_STATE", state); securedController = (SecuredController) context.getBean("tasksController"); try { ModelAndView mav = securedController.processFormSubmission(request, response, null, new BindException(currentUser, "test")); Assert.fail("Invalid Action exception expected"); } catch (Exception e) { } } @Test public void testProcessFormSubmissionValidActionWithUser() throws Exception { MockHttpServletRequest mockRequest = new MockHttpServletRequest(); mockRequest.addParameter("actionName", "default"); request = mockRequest; FakeUIFWApplicationState state = new FakeUIFWApplicationState(); User currentUser = new User("test1", new String[] { "test/test1" }, "token1"); state.setCurrentUser(currentUser); request.getSession().setAttribute("APPLICATION_STATE", state); securedController = (SecuredController) context.getBean("tasksController"); ModelAndView mav = securedController.processFormSubmission(request, response, null, new BindException(currentUser, "test")); Assert.assertEquals(mav.getViewName(), "tasks"); } @Test public void testGetCurrentUser() throws Exception { FakeUIFWApplicationState state = new FakeUIFWApplicationState(); User currentUser = new User("test1", new String[] { "test/test1" }, "token1"); state.setCurrentUser(currentUser); request.getSession().setAttribute("APPLICATION_STATE", state); securedController = (SecuredController) context.getBean("tasksController"); String userName = securedController.getCurrentUserName(request); Assert.assertEquals("test1", userName); }}
