Hi, I was trying to run the tests locally following the guide, but I was getting an error, later I figure out that I needed mercurial installed, that requirement is not indicated on the guide.

Expected Result

Pass all the tests following the guide.

Actual Result

I was unable to pass the tests following the guide.

I would be happy to send a pull request later 😄

Sounds like this could be fixed with a small PR to note that mercurial should be installed! Looking forward to seeing that, @stsewd. Thanks for logging this.
