"""
Examples of test function/method attribute usage with patched nose
Simple syntax (-a, --attr) examples:
* nosetests -a status=stable
=> only test cases with attribute "status" having value "stable"
* nosetests -a priority=2,status=stable
=> both attributes must match
* nosetests -a tags=http
=> attribute list "tags" must contain value "http" (see test_foobar()
below for definition)
* nosetests -a slow
=> attribute "slow" must be defined and its value cannot equal to False
(False, [], "", etc...)
* nosetests -a !slow
=> attribute "slow" must NOT be defined or its value must be equal to False
Eval expression syntax (-A, --eval-attr) examples:
* nosetests -A "not slow"
* nosetests -A "(priority > 5) and not slow"
This example and the accompanied patch is in public domain, free for any use.
