Cleanup after all junit tests

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>

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.

Just encountered the same problem.
My solution:

• For a global set up: use (lazy) singleton to access something global that requires instantiation before the tests. The first test that accesses this singleton will trigger the global set up process.
• For a global tear down: use a Java shutdown hook:

  Runtime.getRuntime().addShutdownHook(new Thread(() -> do_your_global_cleanup())));
