Pytest plugin to help with comparing array output from tests

This is a py.test plugin to facilitate the generation and comparison of data arrays produced during tests. The basic idea is that you can write a test that generates a Numpy array (or other related objects depending on the format). You can then either run the tests in a mode to generate reference files from the arrays, or you can run the tests in comparison mode, which will compare the results of the tests to the reference ones within some tolerance. At the moment, the supported file formats for the reference files are: - A plain text-based format (baSed on Numpy loadtxt output) - The FITS format (requires astropy). With this format, tests can return either a Numpy array for a FITS HDU object.
