We added tests to verify that languages actually exported the language they contain, but the way the test is written, it only works correctly in Node, since AMD passes the result through a callback, not as the return value to require. So our tests were failing in the browser.
I just made the test not run in the browser, and then verified it using a local instance of momentjs.com.
repairing language tests
That makes sense. Thanks!
This is due to a hack I wrote to simulate require('moment') when running nodeunit in the browser.
