assert_visit_images_equal

lsst.images.tests.assert_visit_images_equal(tc: TestCase, a: VisitImage, b: VisitImage, *, expect_view: bool | None = None) → None

Assert that two VisitImage instances carry the same persistent state.

Extends assert_masked_images_equal with the VisitImage-specific attributes (PSF, filter, observation info, detector, aperture corrections, photometric scaling, backgrounds, polygon bounds, summary stats) so a round-trip check on a VisitImage does not silently miss differences in any of them.

Parameters

tc

Test case providing the assertion methods to use.

a

First visit image to compare.

b

Second visit image to compare.

expect_view

If not None, also assert whether b shares memory with a (i.e. is a view).
