Thanks to everyone who responded with good advice. It is still
percolating in my mind, and I haven't applied these thoughts to the
suite that was giving me such trouble.
But I wanted to say that you have done me some good, and my newer code
has test suites that are more easily maintained.
I was reminded of this thread when watching Gary Bernhardt's talk
<URL:http://us.pycon.org/2011/schedule/presentations/172/> at Pycon
2011, “Units Need Tests Too” (video at <URL:http://pycon.tv/video/70/>).
Gary is a stickler for many of the principles I adhere to about tests,
which made me more receptive to his practical advice to *not* test some
I hope this can help someone in a similar situation in future,
preferably before their test suite becomes a monster.
