[lawrence.andrews]

> We need a common manual test framework code that can be shared across all the client manual test. This framework class should have the following
> 1) Frame which contains test instruction .
> 2) Pass & Fail button so that user can mark the test pass or fail
> 3) Upon failing the test user should be able to elaborate why the test failed and this can be added to the test failure. 
> 4) Disposing of all the frames.
