[John Bresnahan]

The functional test test_scrubber.py has a function wait_for_scrub() that is not a member of an BaseTest object, yet it makes a call to self.fail() when a problem occurs. self is an invalid reference.

    Invalid reference to self in functional test test_scrubber.py

    In the test_scrubber.py the function wait_for_scrub() makes a
    reference to self even tho it is not a member of any class and
    has no such reference in its scope. This patch makes that
    function a method in the test class so that it can assert the
    failure which it intends.
