Class TemporaryFolder

java.lang.Object
  extended by org.junit.rules.ExternalResource
      extended by org.junit.rules.TemporaryFolder
All Implemented Interfaces:
TestRule

public class TemporaryFolder
extends ExternalResource

The TemporaryFolder Rule allows creation of files and folders that should be deleted when the test method finishes (whether it passes or fails). Whether the deletion is successful or not is not checked by this rule. No exception will be thrown in case the deletion fails.

Example of usage:

 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");
      // ...
     }
 }
