I signed the CLA after the pull request.

[IgorMinar]

we should write a unit test for this. would you mind doing that?

[Narretz]

I'll give it a shot. I guess the test should check if the generated url is in the correct format, yes?

[bbhoss]

This is extremely annoying and an easy fix. Please merge this so I don't have to keep manually editing the URL. I fixed this and was about to send a pull request when I saw this. Now this will probably sit here forever waiting on a unit test for docs.

[IgorMinar]

@bbhoss feel free to post a PR with the missing test

[IgorMinar]

@bbhoss nevermind. I'll just do it. but next time please do send a PR with a test instead of posting a comment like that.

@IgorMinar Didn't mean to come off as rude, it's just that this issue was really annoying, and you know as well as I do how often "waiting on a test" is the death status to many pull requests. I spent about a half hour trying to figure out how to test this change, as the function is buried a few levels deep and I didn't really understand Doc at all. Thanks for writing the test!
