@jdm I don't fancy an inline code like this but the code below would fail:

promise_test(function (p) {
  promise_rejects(p, new TypeError(), function () {
    register_sw('./in%5Csome%5fdir/sw.js');
  });
}, "Test: Throws Error when Invalid Url Path");

That's because it needs to return the result of register_sw.
