Here's what the first ever build status badge looked like:
Now they've become part of the trust chain in a project. The green badge instills confidence that the project maintainer is not only actively writing test, but that they're also caring for having the automated build pass.
They've gotten so popular that a group of fine people huddled together to build Shields, a common endpoint and provider of unified status badges.
Shields was the driving force behind the unified PNG badges that have been in use for the past couple of months (), and lately, they've been pushing towards badges based on SVG. With Retina being everywhere, it was about time that Travis CI provided better, scalable badges as well.
As of today, badges displayed in Travis CI are based on the SVG version, and our status image dialog shows them as defaults as well. Here's an example of how they look, fingers crossed the build is green!
For the time being, we'll still serve the PNG files on the old URLs, but we'll eventually serve the SVG version by default for both URLs.
Many thanks to the Shields project for providing us with these badges and for pushing towards them being unified across all projects actively using them.
