Test of num_regression user message failing

[nicoddemus]

tests/test_num_regression.py:test_common_cases currently fails when running from a virtual environment on Windows because it produces this message:

data1:
          obtained_data1         ...                          diff
500  1.20000000000000018         ...           0.10000000000000009

While the expected was this one:

data1:
          obtained_data1       expected_data1                 diff
500  1.20000000000000018  1.10000000000000009  0.10000000000000009

It seems there's some issue with how pandas formats the tables.

The weird thing is that the same test passes when run inside our conda environment.

The test has been marked as xfail for now.

I think I know how to fix it
Let's see

Did you merge the branch with this test tests/test_num_regression.py:test_common_cases ?

[nicoddemus]

Oh that's cool, wait up I will open the PR.

Might have to do with different terminal width, check this: https://stackoverflow.com/questions/11707586/python-pandas-how-to-widen-output-display-to-see-more-columns

A configuration like pd.set_option('display.width', 1000) might help.
