autowisp.tests.test_custom_group_values module

Class Inheritance Diagram

Tests for evaluating quantities over a photref group’s members.

A photref group is given as its members, (image, channel) pairs that may span sessions, and each member is one point, with a quantity’s slot bound to that member’s own channel.

The fixture is one group over two nights, mixing what has to be told apart: an image that is a member in both G0 and G1; one that is a member only in G1 but has a G0 value too, which must not be read; a non-member on the first night, whose outlying values would shift any aggregate they leaked into; a member on the second night; and a member with nothing recorded in its channel.

class autowisp.tests.test_custom_group_values.TestCustomGroupValues(methodName='runTest')

Bases: TestCase

Quantities over an explicit list of members, one point each.

static _add_sessions(db_session)

Add the two nights, returning {label: ObservingSession}.

_assert_values(actual, expected)

Compare arrays holding NaN, which never equals itself.

_evaluate(quantities, expressions=None, members=None)

Return get_custom_group_values() over the group, in a session.

Members are handed over in reverse, so that the order they come back in is the function’s doing.

_expected(per_member)

Return per_member of the group’s members, as a list.

classmethod _fill_database()

Two nights of object frames, holding the group and one other.

Provenance foreign keys are left dangling, as SQLite does not enforce them and nothing here reads them.

classmethod setUpClass()

Hook method for setting up class fixture before running tests in the class.

classmethod tearDownClass()

Hook method for deconstructing the class fixture after running all tests in the class.

test_a_quantity_comparing_channels_is_refused()

A member has one channel to bind, its own.

test_a_quoted_channel_is_read_for_every_member()

Whatever the member’s own channel, including for image 0 twice.

test_an_aggregate_spans_the_whole_group()

Both nights and both channels, and nothing outside the group.

The median of the members’ 1, 2, 4 and 8 is 3; image 2’s 100 and 200 would move it, and so would image 1’s G0 value.

test_each_member_reads_its_own_channel()

Image 0 twice, in each channel; image 1 in G1 only.

test_the_time_is_read_per_member()

Channel-free, so the same for both of image 0’s entries.
