ObsTests
¶ Bases:
lsst.obs.base.butler_tests.ButlerGetTests
,lsst.obs.base.mapper_tests.MapperTests
,lsst.obs.base.camera_tests.CameraTests
Aggregator class for all of the obs_* test classes.
Inherit from this class, then lsst.utils.tests.TestCase, in that order.
Example subclass:
class TestObs(lsst.obs.base.tests.ObsTests, lsst.utils.tests.TestCase): def setUp(self): self.setUp_tests(...) self.setUp_butler_get(...) self.setUp_mapper(...) self.setUp_camera(...)

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 }
