  @Before
  public void setUp(){
      objectUnderTes         


        

Answer 1

Use the @Rule annotation and the TemporaryFolder classfor the folder that you need to delete.

http://kentbeck.github.com/junit/javadoc/4.10/org/junit/Rule.html (404 not found)

Update example of usage by http://junit.org/junit4/javadoc/4.12/org/junit/rules/TemporaryFolder.html:

public static class HasTempFolder {

  @Rule
  public TemporaryFolder folder= new TemporaryFolder();

  @Test
  public void testUsingTempFolder() throws IOException {
    File createdFile= folder.newFile("myfile.txt");
    File createdFolder= folder.newFolder("subfolder");
    // ...
  }

}
