karma-babel-polyfill

A Karma plugin that injects babel-polyfill into the test browser environment, ensuring that ES2015+ APIs (e.g., Promise, Map, Set) are available when running tests with Karma. Version 0.0.5 is the final release; the package has not been updated since 2016 and is considered deprecated in favor of using @babel/polyfill or @babel/regenerator directly with Karma's configuration. It requires karma as a peer dependency and is designed for use with older Babel 6 setups.
