Canary What ? In software testing, a canary (also called a canary test) is a push of programming code changes to a small number of end-users who have not volunteered to test anything. The goal of a canary test is to make sure code changes are transparent and work in a real-world environment. Canary tests, which are often automated, are run after testing in a sandbox environment has been completed. Because the canary is only pushed to a small number of users, its impact is relatively small should the new code prove to be buggy and changes can be reversed quickly....
