Class Overview

The TemporaryFolder Rule allows creation of files and folders that are guaranteed to be deleted when the test method finishes (whether it passes or fails): 

 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");
 		// ...
 	}
 }
