Re: [Matplotlib-users] from pylab import nx?

You should turn them into unit tests as well as examples. The backend_driver.py example runs a number of other examples using a number of different backends. That's been a reasonably successful set of regression and coverage tests. It's not perfect, but it's a start. There are also some lower-level unit tests for frequently-reoccurring bugs in the unit directory.

Indeed, is there any kind of full unit test suite that a developer can run when changing things ot make sure they haven't fubarred anything? backend_driver.py is, AFAIK, the closest thing to that. I recently did a coverage analysis of it (with coverage.py), and it hits something like 98% of the non-error case code, so it's pretty good. What we don't have is an automated regression test framework to see if the results remain correct. There are a number of reasons why this is a non-trivial task -- there was a thread about that on this list a few months ago. Unfortunately, I can't find it... Maybe someone else remembers the subject line?

Not sure if this is relevant, but NX is a frequently used shorthand for the NetworkX graph/network analysis package from Los Alamos National Labs: https://networkx.lanl.gov/reference/networkx/networkx-module.html i.e. people do: import NetworkX as nx It has a sub-package for drawing networks in pylab (networkx.drawing.nx_pylab). Maybe at some point someone was trying to integrate NetworkX with pylab directly and some tests got left laying around? The NetworkX guys would probably know. -- Zane Selvans Amateur Human [EMAIL PROTECTED] 303/815-6866 PGP Key: 55E0815F begin:vcard fn:Zane Selvans n:Selvans;Zane org:Earthlings adr:;;200 S.
