This can be useful in naming objects and in custom logging. Right now the user has to find some way to record it separately, but TestComplete already knows this name so it should be easy to expose. ...
Being able to reference the current test as an object would be helpful too. For example I am currently writing a bunch of new automation tests and find myself reusing several steps/tests with Code Expressions in them. These Code Expressions almost always reference the current Keyword Test using the KeywordTests.<TestName>.Variables.<Variable> format. Since I am copy/paste-ing these steps from test to test I frequently forget to go back and adjust my Code Expressions so I'll have one test trying to evaluate a value from a completely different test. Having a ThisTest.Variables.<Variable> object instead, so that when I copy/paste from one test to another I don't have to go in and fix it would be a BIG help.
