test_args in PR

[Francesco Bonazzi]

In the PR:

https://github.com/sympy/sympy/pull/10180/

There is a test failure in test_args that I cannot reproduce on my computer.

Output is:

________________________________________________________________________________

sympy/core/tests/test_args.py:test_sympy__tensor__array__dense_ndim_array__ImmutableDenseNDimArray

File "/home/travis/virtualenv/pypy-2.5.0/site-packages/sympy-0.7.7.dev0-py2.7.egg/sympy/core/tests/test_args.py", line 3191, in test_sympy__tensor__array__dense_ndim_array__ImmutableDenseNDimArray

from sympy.tensor.array.dense_ndim_array import ImmutableDenseNDimArray

ImportError: No module named sympy.tensor.array

File "/home/travis/virtualenv/pypy-2.5.0/site-packages/sympy-0.7.7.dev0-py2.7.egg/sympy/core/tests/test_args.py", line 3197, in test_sympy__tensor__array__sparse_ndim_array__ImmutableSparseNDimArray

from sympy.tensor.array.sparse_ndim_array import ImmutableSparseNDimArray

ImportError: No module named sympy.tensor.array

This is the case for PyPy, but it's the same with all supported versions of CPython.

On my computer, these tests pass.

Is there a bug or am I missing something?

The code of the tests I added is here:

Hi,

Test logs show that sympy.tensor.array module is not getting installed. https://travis-ci.org/sympy/sympy/jobs/93753616#L713

You have to add it to the modules list in setup.py for the files to get installed.
