Thanks for these improvements, anastasia -

i) the actual fix could still see some redundancy removed. Consider an implementation of the form beginning

fluid.each(["success", "error"], function (callbackName) { .....

ii) there are unnecessary calls to "makeCallbackFunction" in the tests as well as unnecessary expression of 
the arguments - also the fluid.tests namespace whilst used only in tests will still eventually be subject to 
congestion. Could you supply more meaningful names to "testSuccessFunction", "callbackFilenames" etc? Or 
even remove them entirely by the same consideration applied in i).

A suitable way of expressing the tests might be as follows:

..... () {
     var filenames = {
         success: "Caching-test.html",
         error: "Foofer.doodle"
     var successCases = [{
         name: "No success callback",
         callback: null},{
         name: "Literal success callback",
         callback: fluid.tests.testSuccessFunction},{
         name: "Named success callback",
         callback: "fluid.tests.testSuccessFunction"]
     var errorCases = [{
         name: "No error callback",
         callback: null},{
         name: "Literal error callback",
         callback: fluid.tests.testErrorFunction},{
         name: "Named error callback",
         callback: "fluid.tests.testErrorFunction"
     fluid.each(successCases, function(scase), {
         fluid.each(errorCases, function(ecase), {
             fluid.tests.testFetchResourcesCallbacks("FLUID-4576: fetchResources callback with " +
                 scase.name + " and " + ecase.name, filenames, scase.callback, ecase.callback);

This would succeed in testing a lot more of the implementation surface with smaller and more readable test 
case bulk. You can see examples of this kind of "structure-driven test case" for example in our Uploader 
tests at


JavaScript is a great environment for writing test cases!
