tschaub/karma-polyfill

The karma-polyfill project is a plugin for Karma that loads polyfills from polyfill.io before running tests, ensuring compatibility with older browsers. This plugin is ideal for developers who need to run cross-browser tests and want to ensure their code works seamlessly across different environments. By installing and configuring karma-polyfill, developers can easily polyfill specific features, such as Promise or fetch, for their test suites.
