Cleanup after all junit tests

Question

In my project I have to do some repository setup before all tests. This is done using some tricky static rules. However I've got no clue how to do clean up after all the tests. I don't want to keep some magic static number referring the number of all test methods, which I should maintain all the time.

The most appreciated way is to add some listener which would be invoked after all the tests. Is there any interface for it already in JUnit4?

edit: this has nothing to do with @BeforeClass and @AfterClass, cause I have to know if method annotated with @AfterClass is invoked for the last time.

Answer 1

I'm using JUnit 4.9. Will this help?:

import junit.framework.TestCase;  import org.junit.AfterClass; import org.junit.BeforeClass; import org.junit.runner.RunWith; import org.junit.runners.Suite; import org.junit.runners.Suite.SuiteClasses;  @RunWith(Suite.class) @SuiteClasses({First.class,Second.class,Third.class}) public class RunTestSuite extends TestCase {     @BeforeClass     public static void doYourOneTimeSetup() {         ...     }      @AfterClass     public static void doYourOneTimeTeardown() {         ...     }     } 

Edit: I am quite positive (unless I misunderstand your question) that my solution is what you are looking for. i.e. one teardown method after all your tests have ran. No listener required, JUnit has this facility. Thanks.

Answer 2

I recommend to use org.junit.runner.notification.RunListener, example:

public class TestListener extends RunListener {   @Override   public void testRunStarted(Description description) throws Exception {      // Called before any tests have been run.   }   @Override   public void testRunFinished(Result result) throws Exception {      // Called when all tests have finished   } } 

Read more directly in JUnit java doc. You can use that even with Maven's surefire (unit tests) plugin or failsafe plugin (integration tests) by adding following code into plugin configuration:

<properties>   <property>     <name>listener</name>     <value>com.innovatrics.afismq.it.TestListener</value>   </property> </properties>
