Version: 0.3.3

OS: MacOS

Install method: npm

Description:

I have helper used in multiple test which is getting author everytime new test is created. Due to that unnecessary execution time is there. We should replay the helper.

@Akanshsin Thanks for reporting this but this is how the current helper implementation is intended to be.
Converting this to enhancement request where we add support for same helper to be used across multiple authoring testmds.
