dummyFrontendURL could as well be an argument to openInspector, since it is not
used anywhere else, and globals are evil, as we know :)

+1, please pass front-end URL as an explicit parameter.

     inspectorFrontend.addEventListener("load", function(event) {
         // FIXME: rename this 'test' global field across all tests.
         var testFunction = window.test;
