Is there anything you'd like reviewers to focus on?

I'm not sure that the tests are fixed properly, so please focus on those.

Please provide testing instructions, if applicable:

I tested in following way:

1. Run npm run test

There was no error and it says "371 passing".

2. Run ./bin/http-server ./, check the paths on http://localhost:8080

Result image is above.

This looks good! The failing test is an unrelated non-deterministic issue we're having problems with, I'm going to re-run it until it passes before merging. Thank you!
