Production-Ready Polymer Elements - A How-To-Guide
summary
Polymer maintains over one hundred elements used across 500+ applications and demonstrates a repeatable pipeline: lint with ESLint and PolyLint, unit-test HTML-imported elements with Web-Component-Tester (WCT) using Mocha/Chai/Sinon plus test-fixture and MockInteractions, run an accessibility suite (Chrome Accessibility Developer Tools) and verify behavior in both native and polyfilled Shadow DOM, and run CI on Travis CI with Sauce Labs for cross‑browser coverage; paper-checkbox shows the setup and claims 90% copy‑paste of its test config works for other elements.
