Github pull request "Good to merge"

github, travis-ci

Solution

Once you've set up Travis and tell it which branch need to be tested, it'll automatically run a build on each pull request targetting one of those branches (and every commit pushed to these branches).

Note that the Travis notification on Github only appears after the build/test is over (roughly 15min).

Problem

On Github, I've noticed that some pull requests say that they're "Good to merge" because they have passed a Travis build passed. I have used Travis a little bit, how does it integrate with pull requests on Github? Here's a screenshot of what I'm talking about:
