Amazing work, thank you @ankitrox!

I've left two small comments for your review. Please let me know what you think.

I've also fixed the test failures as otherwise, merging this PR would result in test failures in develop.

Thanks @nfmohit

That's a nice suggestion to have a separate bash file. I've added it and sending your way for another look.

LGTM, thank you @ankitrox!

Note: I've moved the bash file to the tests/js/bin directory and added an environment variable for the Jest results file to avoid repetition.
