testing test_sage.py

[Ralf Stephan]

Hello,

the most recent Sage has sympy-0.7.5. When testing the sympy file test_sage.py using

./sage -t local/lib/python2.7/site-packages/sympy/external/tests/test_sage.py

I get six fails, the same with Sage-6.2+sympy-0.7.4. Now I'm asking myself, how does the sympy test robot test the git master version? Wouldn't git master first have to be adapted to Sage? How do you do that automagically?

If the test_sage.py file is not tested I would be happy to open a ticket /wrt to the failing code.

Regards,

Hi Ralf,

Thanks for looking into it. We test against Sage regularly on Travis.
Here is the part that installs Sage:

https://github.com/sympy/sympy/blob/4a732fd3234043baef640ab65ec9900bca802780/.travis.yml#L114

and here is the actual test:

https://github.com/sympy/sympy/blob/4a732fd3234043baef640ab65ec9900bca802780/bin/test_travis.sh#L16

But it should be noted, that the Sage tests are in the "can fail" category:

https://github.com/sympy/sympy/blob/4a732fd3234043baef640ab65ec9900bca802780/.travis.yml#L77

But if you look at the Travis tests:

https://travis-ci.org/sympy/sympy/builds

e.g.:

https://travis-ci.org/sympy/sympy/builds/43339863

I can't find the Sage tests. Any ideas what's going on?

Yes. This command

sage -python bin/test sympy/external/tests/test_sage.py 

will fail right at the start because SymPy's bundling of mpmath interfers

with Sage's bundling of mpmath. That's why, in Sage's recent upgrade

to sympy-0.7.5, we applied Sergey's patch that removes SymPy's mpmath.

So, only the testing of the SymPy version included with Sage works (via

sage -t), but not that of git master.

On unbundling of mpmath from SymPy please see

https://github.com/sympy/sympy/pull/2192

Sure, but we should be able to see this failure at Travis, and I don't
see anything. That's why I am asking.

Yes, this will be applied soon.
