6. public void persist(Foo foo) { entityManager.persist(foo); } public List find() { return entityManager.createQuery("from Foo").getResultList(); } public List findByName(String name) { CriteriaBuilder cb = entityManager.getCriteriaBuilder(); CriteriaQuery query = cb.createQuery(Foo.class); Root root = query.from(Foo.class); query.where(cb.equal(root.get(Foo_.name), name)); return entityManager.createQuery(query).getResultList(); } Unit Tests Arent Always Best

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

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

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

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

23. @Autowired private DispatcherServlet servlet; @Autowired private SomeRepository repository; @Test public void viewTest() throws Exception { MockHttpServletRequest request = new MockHttpServletRequest("GET", "/view"); request.addParameter("id", "0"); MockHttpServletResponse response = new MockHttpServletResponse(); servlet.service(request, response); String results = response.getContentAsString().trim(); Assert.assertEquals( " Hello World! ", results); } An Example Test

24. @Test public void saveTest() throws Exception { MockHttpServletRequest request = new MockHttpServletRequest("POST", "/"); request.addParameter("name", "Ted"); MockHttpServletResponse response = new MockHttpServletResponse(); servlet.service(request, response); Assert.assertEquals("Ted", repository.find(1).getName()); } Prepare and Review Model

25. @Test(expected=NestedServletException.class) public void saveFailedTest() throws Exception { MockHttpServletRequest request = new MockHttpServletRequest("POST", "/"); request.addParameter("name", ""); MockHttpServletResponse response = new MockHttpServletResponse(); servlet.service(request, response); } Test Validation

26. @Test(expected=NestedServletException.class) public void secureFailedTest() throws Exception { MockHttpServletRequest request = new MockHttpServletRequest("GET", "/secure/view"); MockHttpServletResponse response = new MockHttpServletResponse(); servlet.service(request, response); } Test Security

27. @Test public void secureTest() throws Exception { SecurityContextHolder.getContext().setAuthentication( new UsernamePasswordAuthenticationToken( "Ted", "password")); MockHttpServletRequest request = new MockHttpServletRequest("GET", "/secure/view"); MockHttpServletResponse response = new MockHttpServletResponse(); servlet.service(request, response); String results = response.getContentAsString().trim(); Assert.assertEquals( " Hello Ted! ", results); } Test Security
