I have apparent interference between doctests embedded in the docstrings of different methods, and this interference also appears to be influenced by seemingly irrelevant things such as whether the module has a (non-doctest-containing) docstring or not.
I, and what hair I've not yet torn out, would be most grateful for any suggestions.
I did not see if you have read the doctest.py docstrings... It looks (unsurprisingly ;o) to be quite well documented.
It might be a place to start, anyhow.
Thanks for the suggestion, Lee. :-)
I was working mostly off of the library reference, rather than the code itself. (2600+ l.o.c. is a bit past my level of experience.) But, there's no way to learn but by trying, so I've plunged in.
It is more code than I can currently form a mental model for, but one line does make me think I cannot understand the observed behaviour.
class DocTest.__init__ takes, among its args, globs, where globs is documented as:
globs: The namespace (aka globals) that the examples should
be run in.
The relevant line of the __init__ method says:
self.globs = globs.copy()
Thus, if I understand it aright (a shaky bet at best) there should not be interference between individual doctests. (It seems like each docstring is parsed to create a DocTest object, and each such object has its own copy of the appropriate namespace.
So, no joy (yet) :-( Will dig more. Thanks for the push :-)
Best,
Brian vdB
