Currently there is no way to unit test the private methods in dtjava.js. I'm enabling selective access with my change to the version string (https://javafx-jira.kenai.com/browse/RT-40684) but I don't want the two to mix since the change to this one will be virtually the entire file. So the idea is to do something like this to expose all private methods to unit test and for SQE to test:

var dtjava = function() {
var innerDTJava = {
 (original dtjava stuff here)
 var getDTJava = { /* instead of return { */
   /**
    Version of Javascript part of Deployment Toolkit.
    Increasing lexicographically.
   ...
 }
}
if ((typeof __dtjavaTestHook__ !== 'undefined') && ...) {
 __dtjavaTestHook__ = innerDTJava;
}
return innerDTJava.getDTJava;
}
