Run object instead of runFiles?

In nodeunit, whenever you call

nodeunit.reporters["default"].run(["a","b"]);

it will always, eventually, require("a") as a test and run it, then require("b") and then run it.

What if you want to load files on your own, or even define tests in memory, never saving to a file? As an example, I could see loading a file, doing some manipulation, and only then passing it through to nodeunit.

In this scenario, the two run() calls below would be equivalent:

var a = require("a");
nodeunit.reporters["default"].run(["a"]);
nodeunit.reporters["default"].runModule(a);

But the second option gives me the ability to do:

var a = require("a");
a.doSomeMod();
nodeunit.reporters["default"].runModule(a);

Even better, you don't need runModule. All you need is for run() to check each option in the array; if it is a string, require() it as a file, else just use it as is.

Whole change set could probably be done in nodeunit.js ll 61-81.

Start in nodeunit.js around lines 61–81 and inspect how the default reporter's run method handles its input array and requires test files. Compare the requested file-based and in-memory module cases, then verify that both forms execute correctly and that the existing behavior remains intact.
