/*
* worker-test-harness should be considered a temporary polyfill around
* testharness.js for supporting Service Worker based tests. It should not be
* necessary once the test harness is able to drive worker based tests natively.
* See https://github.com/w3c/testharness.js/pull/82 for status of effort to
* update upstream testharness.js. Once the upstreaming is complete, tests that
* reference worker-test-harness should be updated to directly import
* testharness.js.
