"""
Test aggregator for obs_* packages.
 
The intention is for each obs package to have a single test class that inherits
from this collector class, thus "automatically" getting all new tests. If those
tests require setup that isn't defined in a given obs package, that obs package
will be broken until updated. This is intentional, as a way to prevent obs
packages from falling behind out of neglect.

        ----------
        butler: lsst.daf.persistence.Butler
            A butler object, instantiated on the testdata repository for the
            obs package being tested.
        mapper: lsst.obs.CameraMapper
            A CameraMapper object for your camera, instantiated on the testdata
            repository the obs package being tested.
        dataIds: dict
            dictionary of (exposure name): (dataId of that exposure in the
            testdata repository), with unittest.SkipTest as the value for any
            exposures you do not have/do not want to test. It must contain a
            valid 'raw' dataId, in addition to 'bias','flat','dark', which may
            be set to SkipTest. For example::
