Currently TestNG provides the following two ways in which one can intercept test or config executions

• IHookable
• IConfigurable

Today TestNG does not distinguish between a successful invocation vs a wilful skip of invoking the callback and so if a user within their run() implementation, decided to never patch through the callback, TestNG would still classify that method as passed.

This issue is to track this discrepancy and arrive at a proper solution.
