LEDMatrix/test/test_web_settings_ui.py

"""
Smoke tests for the settings tooltips + search UI.

These render the settings partials through Flask and assert that every settings
field carries:
  - a stable search anchor id (`id="setting-..."` on its .form-group), and
  - an info tooltip (`class="help-tip"` emitted by the help_tip macro).

They guard against macro/import breakage and against fields losing their anchor
or tooltip when partials are edited. See web_interface/static/v3/js/tooltips.js
and settings-search.js for the consumers of this markup.
