  6. Unit Tests Aren’t Always Best • publicvoid persist(Foo foo) { • entityManager.persist(foo); • } • public List<Foo> find() { • returnentityManager • .createQuery("from Foo").getResultList(); • } • public List<Foo> findByName(String name) { • CriteriaBuildercb = entityManager.getCriteriaBuilder(); • CriteriaQuery<Foo> query = cb.createQuery(Foo.class); • Root<Foo> root = query.from(Foo.class); • query.where(cb.equal(root.get(Foo_.name), name)); • returnentityManager.createQuery(query).getResultList(); • }

  12. Testing a Controller Controller Servlet Container

  13. Testing a Spring MVC Controller Controller Spring MVC Servlet Container

  14. Testing a Spring MVC Controller Controller Spring MVC Transactions Request Mapping View Resolution Servlet Container

  15. Testing a Spring MVC Controller Controller Spring MVC Transactions Request Mapping View Resolution DispatcherServlet Servlet Container

  16. Mocking DispatcherServlet DispatcherServlet

  17. Mocking DispatcherServlet DispatcherServlet WebApplicationContext

  18. Mocking DispatcherServlet DispatcherServlet WebApplicationContext ServletConfig ServletContext

  19. Spring and JUnit • @RunWith(SpringJUnit4ClassRunner.class) • @ContextConfiguration(locations="classpath:spring.xml") • publicclassSomeControllerTests { • ... • }

  20. Spring and JUnit • @RunWith(SpringJUnit4ClassRunner.class) • @ContextConfiguration( locations="classpath:spring.xml", loader=MockWebApplicationContextLoader.class) • publicclassSomeControllerTests { • ... • }

  21. Spring and JUnit • @RunWith(SpringJUnit4ClassRunner.class) • @ContextConfiguration( locations="classpath:spring.xml", loader=MockWebApplicationContextLoader.class) • @MockWebApplication( name="some-controller",webapp="/src/main/webapp") • publicclassSomeControllerTests { • ... • }

  22. View Technologies • How Many Use: • JSPs • Velocity • Freemarker • Facelets

  23. An Example Test • @Autowired • privateDispatcherServletservlet; • @Autowired • privateSomeRepositoryrepository; • @Test • publicvoidviewTest() throwsException{ • MockHttpServletRequestrequest = • newMockHttpServletRequest("GET", "/view"); • request.addParameter("id", "0"); • MockHttpServletResponseresponse = • newMockHttpServletResponse(); • servlet.service(request, response); • String results = response.getContentAsString().trim(); • Assert.assertEquals( • "<html><body>Hello World!</body></html>", • results); • }

  24. Prepare and Review Model • @Test • publicvoidsaveTest() throws Exception { • MockHttpServletRequestrequest = • newMockHttpServletRequest("POST", "/"); • request.addParameter("name", "Ted"); • MockHttpServletResponseresponse = • newMockHttpServletResponse(); • servlet.service(request, response); • Assert.assertEquals("Ted", repository.find(1).getName()); • }

  25. Test Validation • @Test(expected=NestedServletException.class) • publicvoidsaveFailedTest() throws Exception { • MockHttpServletRequestrequest = • newMockHttpServletRequest("POST", "/"); • request.addParameter("name", ""); • MockHttpServletResponseresponse = • newMockHttpServletResponse(); • servlet.service(request, response); • }

  26. Test Security • @Test(expected=NestedServletException.class) • publicvoidsecureFailedTest() throwsException { • MockHttpServletRequestrequest = • newMockHttpServletRequest("GET", "/secure/view"); • MockHttpServletResponseresponse = • newMockHttpServletResponse(); • servlet.service(request, response); • }

  27. Test Security • @Test • publicvoidsecureTest() throwsException { • SecurityContextHolder.getContext().setAuthentication( • newUsernamePasswordAuthenticationToken( • "Ted", "password")); • MockHttpServletRequestrequest = • newMockHttpServletRequest("GET", "/secure/view"); • MockHttpServletResponseresponse = • newMockHttpServletResponse(); • servlet.service(request, response); • String results = response.getContentAsString().trim(); • Assert.assertEquals( • "<html><body>Hello Ted!</body></html>", • results); • }
