Canary testing refers to a software release management strategy where a new version of the application is rolled out to a small subset of users before being made available to the larger population. The term “canary” comes from the phrase “canary in a coal mine,” referring to the practice of sending canaries into mines to detect dangerous gases. In this analogy, the canaries are the early users, and the goal is to catch any issues before they affect the larger system or user base. https://testomat.io/blog/canary-testing-the-key-to-safe-software-releases/
