Re: [matplotlib-devel] nosetests: too slow, too much memory

[Benjamin R. <ben...@ou...>]

Just noticed an oddity with the tests on Travis versus the tests on my
machine. The test log on Travis for a single run has over 10,000 lines.
But, for me, it is over ~4800 lines. At a glance, I can see that test_mlab
is not executed for me, but they are for Travis. I am very suspicious of
the test_mlab run on Travis because it seems to be running multiple times,
but I can't be sure.

Michael, can I get the test log for one of the recent Travis runs?

Thanks,
Ben Root
