How to stop all tests from inside a test or setUp using unittest?

I'm extending the python 2.7 unittest framework to do some function testing. One of the things I would like to do is to stop all the tests from running inside of a test, and inside of a setUpClass() method. Sometimes if a test fails, the program is so broken it is no longer of any use to keep testing, so I want to stop the tests from running.

I noticed that a TestResult has a shouldStop attribute, and a stop() method, but I'm not sure how to get access to that inside of a test.

Does anyone have any ideas? Is there a better way?

I looked at the TestCase class and decided to subclass it. The class just overrides run(). I copied the method and starting at line 318 in the original class added this:

# this is CPython specific. Jython and IronPython may do this differently
if testMethod.func_code.co_argcount == 2:
    testMethod(result)
else:
    testMethod()

It has some CPython specific code in there to tell if the test method can accept another parameter, but since I'm using CPython everywhere, this isn't an issue for me.
