/**
* Execute testharness.js and one or more scripts in an iframe. Report the
* results of the execution.
*
* @param {...function|...string} bodies - a function body. If specified as a
* function object, it will be
* serialized to a string using the
* built-in
* `Function.prototype.toString` prior
* to inclusion in the generated
* iframe.
*
* @returns {Promise} eventual value describing the result of the test
* execution; the summary object has two properties:
* `harness` (a string describing the harness status) and
* `tests` (an object whose "own" property names are the
* titles of the defined sub-tests and whose associated
* values are the subtest statuses).
