+The test cases for an applet reside in the subdirectory of the applet name.
+The name of the test case should be the assertion that is tested.
+The test case should be a shell fragment that returns successfully

 "FEATURE: " followed by the name of the feature in a comment.  If it is always
 expected to fail, it should include the string "XFAIL" in a comment.
