autowisp.tests.test_photometry_slots module

Class Inheritance Diagram

Tests for photometry slots in diagnostic expressions.

The second subscript, magfit_residual[0][1], binding the photometries of a quantity read per photometry as the first binds its channels. Kept apart from autowisp.tests.test_expressions only for length; the fixture is its SlotTestCase, with a per-photometry diagnostic added.

class autowisp.tests.test_photometry_slots.TestPhotometrySlots(methodName='runTest')

Bases: SlotTestCase

Photometries, bound through a second subscript as channels are through the first.

The library adds to the channel one: two photometries of one channel; one formal photometry against a quoted aperture; an expression passing its photometries on the other way round; one quoting both its channel and its photometry, the shape fit; and a channel-free one taking a photometry, and one reading that.

fetch(wanted)

As for any diagnostic, with magfit_residual per photometry.

magfit_residual per channel and photometry, distinct everywhere so that reading the wrong one cannot pass by coincidence.

test_a_read_must_match_what_it_reads()

A photometry subscript exactly where one is taken, naming one.

test_a_rule_takes_at_most_one_photometry_slot()

The other photometries a rule reads are quoted.

test_evaluated_in_the_photometries_bound()

swapped at (2, shapefit) is apertures at the reverse.

test_needed_in_every_photometry_read()

Formal ones bound, quoted ones read as the ids they spell.

test_parameters_and_arity()

Derived from the second subscripts, as channels from the first.

test_reads_carry_their_photometries()

The second subscript is part of the read, not a read of its own.

test_the_library_accepts_them()

Every shape above is a valid expression.

wanted = {'against_ap4': {(('B',), (0,))}, 'doubled_g': {((), (3,))}, 'g_shapefit': {((), ())}, 'swapped': {(('R',), (2, -1))}}

One of each shape above, all wanted at once.
