Is there a way to know that nodeunit has finished all tests?

I need to run some code after nodeunit successfully passed all tests. I'm testing some Firebase wrappers and Firebase reference blocks exiting nodeunit after all test are run.

I am looking for some hook or callback to run after all unit tests are passed. So I can terminate Firebase process in order nodeunit to be able to exit.

Didn't found a right way to do it.

There is my temporary solution:

//Put a *LAST* test to clear all if needed:
exports.last_test = function(test){
    //do_clear_all_things_if_needed();
    setTimeout(process.exit, 500); // exit in 500 milli-seconds    
    test.done(); 
} 

In my case, this is used to make sure DB connection or some network connect get killed any way. The reason it works is because nodeunit run tests in series.

It's not the best, even not the good way, just to let the test exit.

For nodeunit 0.9.0
