Changeset 57257 for trunk/tests/phpunit/tests/hooks/applyFilters.php

Message:

Tests: Add hook priority call order tests.

Adds happy (integer) and unhappy (non-integer) tests for validating the priority call order for:

• do_action()
• WP_Hook::do_action()
• apply_filters()
• WP_Hook::apply_filters()

As each of these functions have differing code, the tests are added to each to ensure expected results and protect against future regressions.

Follow-up to [53804], [52010], [25002], [25/tests], [62/tests].

Props hellofromTonya, mukesh27, dd32, valendesigns, drrobotnik.
Fixes #60193.
