During the development of this polyfill, I noticed a defect in the WHATWG DOM specification (patch 1, patch 2). The finding is acknowledged at https://dom.spec.whatwg.org/#acks.
By default the tests run against the code in src/. Any native TreeWalker
implementation is disabled as part of the test set up.
- To test the native implementation, run
UNIT_USE_NATIVE=true npm test. - To test the minified version, run
UNIT_USE_MIN=true npm test. - Both, run
UNIT_USE_MIN=true UNIT_USE_NATIVE=true npm test. - To debug tests in your browser (instead of Headless), use
npm run karma-debug. Then press the "Debug" button in the browser window to start the tests.
