Chore: added tests for options normalize

[anikethsaha]

added tests for lib/options.js

It looks like there might be some overlap with some existing tests here and we'll probably want to colocate them so that they're easier to keep track of. That being said, I'm not against adding a test/lib/options.js file and having it be a centralized location for all options tests!

@kaicataldo I agree I think there are 1-2 tests doing similar but in option testing, I am doing unit test for normalize method instead of running the whole parser. yes, it's not to strong as under the hood, its the same.
I would like to know what you suggest !. cause i think too that this options testing is not so important atm as its already being done under the hood.

let me know

I'm not against unit testing this module, but I do think there's a lot more value in doing a more integration-style test at the parser level.

One small comment, but otherwise this LGTM. I do think there's value in adding some more integration-style tests at the parser level, but it certainly doesn't hurt to have some unit tests here!

LGTM, thanks!
