Annotation Type After

public @interface After

If you allocate external resources in a Before method you need to release them after the test runs. Annotating a public void method with @After causes that method to be run after the Test method. All @After methods are guaranteed to run even if a Before or Test method throws an exception. The @After methods declared in superclasses will be run after those of the current class.

Here is a simple example:
 public class Example {
    File output;
    @Before public void createOutputFile() {
          output= new File(...);
    @Test public void something() {
    @After public void deleteOutputFile() {
