""" 

Test the basic mechanics of coaddition, coadd processing, and forced photometry. 

 

In this test, we build a mock calexps using perfectly knowns WCSs, with the only sources 

being stars created from a perfectly known PSF, then coadd them, process the coadd (using 

the new measurement framework in meas_base), and then run forced photometry (again, using 

the new forced measurement tasks in meas_base). 

 

We do not check that the results of this processing is exactly what we'd expect, except in 

some cases where it's easy and/or particularly important to do so (e.g. CoaddPsf); we mostly 

just check that everything runs, and that the results make enough sense to let us proceed 

to the next step. 

 

NOTE: if this test fails with what looks like a failure to load a FITS file, try changing 

the REUSE_DATAREPO variable below to False, as sometimes this error message indicates a 

different problem that's revealed when we're not trying to cache the mock data between 

tests (but set REUSE_DATAREPO back to True when done debugging, or this test will be very 

slow). 

 

WARNING: This test should not be run with other tests using pytest, and should 

not be discoverable automatically by pytest. The reason for this is that the 

tests rely on 200 MB of data generated on module load, using a single 

directory visible to all the tests. When run in parallel with pytest-xdist 

this data will be created for every sub-process, leading to excessive disk 

usage, excessive test execution times and possible failure.
