"""Canvas and scrollbar fakes for the gate's scroll-viewport tests.
|
|
|
|
Extracted from ``conftest.py`` purely for size: the widget tree the gate builds
|
|
now spans several modules plus ``gatelock``, and the fakes grew past this repo's
|
|
500-line file cap when the scroll viewport and the radio-button unit selector
|
|
were added.
|
|
|
|
Stays under ``tests/`` deliberately. It was briefly moved into the package to
|
|
satisfy the ``test_*.py`` naming hook, but that lost the ruff ``ARG`` exemption
|
|
that ``**/tests/**`` already grants -- and a fake widget's whole job is to
|
|
accept arguments it ignores. Weakening ruff for package code to accommodate
|
|
test scaffolding is the wrong trade; excluding one clearly-named support file
|
|
from a naming convention is the cheaper one.
|
|
|
|
The fakes are *functional* where behaviour matters -- selecting a radio button
|
|
really sets its variable and fires its command, and the canvas really tracks a
|
|
scroll offset -- so a test can drive the gate the way a keyboard user now can,
|
|
rather than merely asserting that a widget was constructed.
