Watching – Refactoring with Science
The presentation about tools and frameworks at GitHub for gaining confidence on changing codes. Test suite provides certain protections against regressions, but there are other spots to cover.
According to the presentation, they are accumulating various statistical metrics, and also automating them through HUBOT commands, along with standard development/deploying workflow on GitHub features.
The above tools are interesting to verify the impact of code change on production load, without changing behavior. It sounds a little similar as Cookpad’s chanko which provides isolated production deploy, but dat-science seems more focusing on experiment than deployment.
