72 1/24/05 PASS ● Pass - the test has been executed correctly and to completion without any kind of problem ● Warning - the functionality is acceptable, but you should be aware that later revisions of the relevant standards or specification may change the requirements in this area. ● FIP - additional information is provided which needs to be checked manually. ● Unsupported - an optional feature is not available or not supported in the implementation under test. ● Not in Use - some tests may not be required in certain test modes or when an interface can be implemented by a macro or function and there are two versions of the test only one is used. ● Untested - no test written to check a particular feature or an optional facility needed to perform a test is not available on the system. www. a 11 y. org

82 1/24/05 FAIL ● ● Fail - the interface did not behave as expected. Uninitiated - the particular test in question did not start to execute.
