How to catch AssertionError in a nested function in JavaScript?

I'm writing a mocha clone, because mocha is lacking certain features that I need. But when I am using existing assertion libraries, I'm unable to catch errors that are returned by them. Here is the code that runs the tests.

Tester.Test = function(name, test_function) {
    this.name = name;
    this.run = function(callback) {
        try {
            test_function(callback);
        } catch (e) {
            callback(e);
        }
    };
};

I've already tried using domain to catch the error, but it's still not working:

var d = domain.create();
d.on("error", function(err) {
    cb(err);
});
d.run(function() {
    test.run(cb);
});

I still keep getting an AssertionError (expected false to be true). Any tips?
