If you want to easily test a submitted pull-request, check this tool that I found while reading a discussion on GitHubGist about how to Checkout github pull requests locally.
For instance, it will let you do things like,
$ git pr $ git pr list closed # not shown by default $ git pr show 7 # also includes comments $ git pr patch 7 # can be piped to colordiff if you like colors $ git pr checkout 7 # create upstream tracking branch pr/7 $ git pr help $ git pr login # Get access token for commands below $ git pr close 7 $ git pr open 7 $ git pr comment 7 'This is good stuff!'
Some commands require a valid login, and open and close will not work if the pull request has been merged. For more information, rtfm.
