34 // only see the html file as a test file. (the harness runs all

36 // were valid as well as the html file.)
37 // Also, note the area= after Your Name in the author tag. Here, you
38 // should put which functional area the test falls in. See the

40 // areas.
41 // Note also the 'InterJVMGetDropSuccessTest.html' in the run tag. This should
42 // be changed to the name of the test.
