Methods Summary
setUp_butler_get
([ccdExposureId_bits, ...])Set up the necessary variables for butlerGet tests.

tearDown
()Check that the butler returns the right type of camera.
Test that we can get a linearizer for good detectorIds.
Do bad detectorIds raise?
Simplest camera test: can we get a Camera instance, and does iterating return Detectors?

()Check the plate scale at center of focal plane
Test expansion of incomplete information of the available data in this obs package's testdata repo.
test_raw
()Test that
raw_header_wcs
returns the unmodified header of the raw image.Methods Documentation

- output
- setUp_tests(butler, mapper, dataIds)¶
Set up the necessary shared variables used by multiple tests.
- Parameters:
- 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:
self.dataIds = {'raw': {'visit': 1, 'filter': 'g'}, 'bias': {'visit': 1}, 'flat': {'visit': 1}, 'dark': unittest.SkipTest }
