Terry J. Reedy added the comment:
class unittest.TextTestRunner(stream=None, descriptions=True, verbosity=1, runnerclass=None, warnings=None)
stream is documented, the others are not (except for some garbled text about warnings). "This class has a few configurable parameters, " is not helpful.
It seems that TextTestRunner was meant to be a subclass of a documented TestRunner class (just as TextTestResult subclasses TestResult), except that is it not.
