"""
Compare output with "truth" using appropriate
diff routine; namely:
* ``fitsdiff`` for FITS file comparisons.
* ``unified_diff`` for ASCII products.
Only after all elements of ``outputs`` have been
processed will the method report any success or failure, with
failure of any one comparison *not* preventing the rest of the
comparisons to be performed.
Parameters
----------
outputs : list of tuple or dict
This list defines what outputs from running the test will be
compared. Three distinct types of values as list elements
are supported:
* 2-tuple : ``(test output filename, truth filename)``
* 3-tuple : ``(test output filename, truth filename, HDU names)``
* dict : ``{'files': (output, truth), 'pars': {key: val}}``
If filename contains extension such as ``[hdrtab]``,
it will be interpreted as specifying comparison of just that HDU.
raise_error : bool
Raise ``AssertionError`` if difference is found.
ignore_keywords : list of str
List of FITS header keywords to be ignored by
``FITSDiff`` and ``HDUDiff``.
ignore_hdus : list of str
List of FITS HDU names to ignore by ``FITSDiff``.
This is only available for ``astropy>=3.1``.
ignore_fields : list of str
List FITS table column names to be ignored by
``FITSDiff`` and ``HDUDiff``.
rtol, atol : float
Relative and absolute tolerance to be used by
``FITSDiff`` and ``HDUDiff``.
input_path : list or tuple
A series of sub-directory names under :func:`get_bigdata_root`
that leads to the path of the 'truth' files to be compared
against. If not provided, it assumes that 'truth' is in the
working directory. For example, with :func:`get_bigdata_root`
pointing to ``/grp/test_data``, a file at::
/grp/test_data/pipeline/dev/ins/test_1/test_a.py
would require ``input_path`` of::
["pipeline", "dev", "ins", "test_1"]
docopy : bool
If `True`, 'truth' will be copied to output directory before
comparison is done.
results_root : str or `None`
If not `None`, for every failed comparison, the test output
is automatically renamed to the given 'truth' in the output
directory and :func:`generate_upload_schema` will be called
to generate a JSON scheme for Artifactory upload.
If you do not need this functionality, use ``results_root=None``.
verbose : bool
Print extra info to screen.
Returns
-------
creature_report : str
Report from FITS or ASCII comparator.
This is part of error message if ``raise_error=True``.
Examples
--------
There are multiple use cases for this method, specifically
related to how ``outputs`` are defined upon calling this method.
The specification of the ``outputs`` can be any combination of the
following patterns:
1. 2-tuple inputs::
outputs = [('file1.fits', 'file1_truth.fits')]
This definition indicates that ``file1.fits`` should be compared
as a whole with ``file1_truth.fits``.
2. 2-tuple inputs with extensions::
outputs = [('file1.fits[hdrtab]', 'file1_truth.fits[hdrtab]')]
This definition indicates that only the HDRTAB extension from
``file1.fits`` will be compared to the HDRTAB extension from
``file1_truth.fits``.
3. 3-tuple inputs::
outputs = [('file1.fits', 'file1_truth.fits', ['primary', 'sci'])]
This definition indicates that only the PRIMARY and SCI extensions
should be compared between the two files. This creates a temporary
``HDUList`` object comprising only the given extensions for comparison.
4. Dictionary of inputs and parameters::
outputs = [{'files': ('file1.fits', 'file1_truth.fits'),
'pars': {'ignore_keywords': ['ROOTNAME']}}]
This definition indicates that ROOTNAME will be ignored during
the comparison between the files specified in ``'files'``.
Any input parameter for ``FITSDiff`` or ``HDUDiff`` can be specified
as part of the ``'pars'`` dictionary.
In addition, the input files listed in ``'files'`` can also include
an extension specification, such as ``[hdrtab]``, to limit the
comparison to just that extension.
This example from an actual test definition demonstrates
how multiple input defintions can be used at the same time::
outputs = [
('jw99999_nircam_f140m-maskbar_psfstack.fits',
'jw99999_nircam_f140m-maskbar_psfstack_ref.fits'
),
('jw9999947001_02102_00002_nrcb3_a3001_crfints.fits',
'jw9999947001_02102_00002_nrcb3_a3001_crfints_ref.fits'
),
{'files': ('jw99999_nircam_f140m-maskbar_i2d.fits',
'jw99999_nircam_f140m-maskbar_i2d_ref.fits'),
'pars': {'ignore_hdus': ['HDRTAB']},
{'files': ('jw99999_nircam_f140m-maskbar_i2d.fits',
'jw99999_nircam_f140m-maskbar_i2d_ref.fits',
['primary','sci','dq']),
'pars': {'rtol': 0.000001}
},
{'files': ('jw99999_nircam_f140m-maskbar_i2d.fits[hdrtab]',
'jw99999_nircam_f140m-maskbar_i2d_ref.fits[hdrtab]'),
'pars': {'ignore_keywords': ['NAXIS1', 'TFORM*'],
'ignore_fields': ['COL1', 'COL2']}
}]
.. note:: Each ``outputs`` entry in the list gets interpreted and processed
separately.

If no differences were found, those file can be deleted.
If any of these calibration files have changed, that probably also has an
effect on /hrma/corr*.dat.
See utils/Makefile for instructions on how to redo those.
If any file name changes, edit marxcaldb.dat, Markefile.in, and marx.lis accordingly; then do git rm, git add

"""
Compare CALXXX output with "truth" using ``fitsdiff``.
Parameters
----------
outputs : list of tuple
A list of tuples, each containing filename (without path)
of CALXXX output and truth, in that order. Example::
[('output1.fits', 'truth1.fits'),
('output2.fits', 'truth2.fits'),
...]
atol, rtol : float
Absolute and relative tolerance for data comparison.
raise_error : bool
Raise ``AssertionError`` if difference is found.
ignore_keywords_overwrite : list of str or `None`
If not `None`, these will overwrite
``self.ignore_keywords`` for the calling test.
verbose : bool
Print extra info to screen.
Returns
-------
report : str
Report from ``fitsdiff``.
This is part of error message if ``raise_error=True``.
