@keshav234156 @jywarren @harshkhandeparkar What are your thoughts on this?
Should we test the options change this way or do you have any other plan in mind?

Please capitalize the first letter and add a full stop at the end of a comment.

Done!

[rishabhshuklax]

@harshkhandeparkar Do you think this is the best way to test this? Or should I look for an alternative?

[harshkhandeparkar]

I guess it is good for now. I don't see any downside to this as of now. (But if we change the modules in the future, it may be a problem)

[rishabhshuklax]

If we change the modules in future the test will fail and corresponding benchark/options can be changed easily, i don't think that would be a problem.

[harshkhandeparkar]

Great. Please make the requested changes.
