  10. So how do we do it? pom.xml: (junit 4.4) spring-core spring-beans spring-tx spring-test 265 + 451 + 216 + 174 = 1,1 MB Thomas Ferris Nicolaisen - Objectware

  11. How? @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "testSpring.xml" }) publicclass TestJUnit4WithSpringTestContextFramework { ... ... Thomas Ferris Nicolaisen - Objectware

  12. Repeat @Test @Repeat(20) publicvoid repeatManyTimes() throws Exception { counter++; int numberOfTimesToRepeat = this. getClass(). getMethod("repeatManyTimes"). getAnnotation(Repeat.class).value(); log.trace("Running for the "+counter+"th time"); if (counter > numberOfTimesToRepeat) { fail( "Should not repeat more than 100 times. counter is "+counter); } } Thomas Ferris Nicolaisen - Objectware

  14. Timeout /** *Thistestwillfailifittakesmorethan50mstoexecute. */ @Test @Timed(millis=50) publicvoid doSomethingBeforeTimeout() throws Exception{ int tryChangingMeTo50 = 20; Thread.sleep(tryChangingMeTo50); } Thomas Ferris Nicolaisen - Objectware

  15. Caching av contexts @Test @DirtiesContext publicvoid doSomethingThatDirtiesTheSpringContext() { // can't really come up with anything that screws the context here.. } Thomas Ferris Nicolaisen - Objectware

  16. Springs exception testing @Test @ExpectedException(RuntimeException.class) publicvoid doSomethingThatThrowsAnException() { thrownew RuntimeException(); } Thomas Ferris Nicolaisen - Objectware

  17. JUnit4 exception testing /** *ThistestexpectsexceptionstheJUnit4way. *It is preferred over the wayabove. */ @Test(expected = RuntimeException.class) publicvoid doSomethingElseThatThrowsAnException() { thrownew RuntimeException(); } Thomas Ferris Nicolaisen - Objectware

  18. Test Profiles @Test @IfProfileValue(name = "mock", value = "true") publicvoid thisWillOnlyBeRunIfTheSystemVariableMockIsTrue() { assertEquals("true", System.getProperty("mock")); } @ProfileValueSourceConfiguration(MyProfileValueSource.class) @IfProfileValue(name="test-groups", values={"unit-tests", "integration-tests"}) publicvoid testProcessWhichRunsForUnitOrIntegrationTestGroups() { // some logic that should run only for unit and integration test groups } Thomas Ferris Nicolaisen - Objectware

  19. Then the real fun begins.. • Use Spring’s data factories • Inject with @Autowired • @ContextConfiguration • Transaction testing • Kan bygges videre på med egne @TestExecutionListeners • Uendelige muligheter! Thomas Ferris Nicolaisen - Objectware
