Trac Ticket: #64895

What?

Converts same-type assertEquals() calls to assertSame() in newer admin/color-scheme and update PHP annotation tests, and documents the remaining intentional loose comparisons (DB numeric strings, POST/user-meta type mismatches, and object value comparisons).

Why?

assertEquals() does not compare types, so it can hide regressions that change a return value’s type, especially falsy values. On #64895, Lance noted loose assertEquals() usage rose from 165 to 183, mostly from new tests. Done looks like either assertSame(), or a short comment explaining why assertEquals() is kept.

How?

• adminColorSchemePicker.php: 10 same-type assertions → assertSame() (string/int/array comparisons).
• wpGetUpdatePhpAnnotation.php: empty-string assertion → assertSame().
• saveAttachmentOrder.php / sendAttachmentToEditor.php: keep assertEquals() with comments (menu_order / post_parent are numeric strings from the DB).
• setScreenOptions.php: keep assertEquals() with comments (integer expectations vs string meta/POST values).
• includesUpdate.php: keep assertEquals() with comments (translation update objects compared by value).

Testing Instructions

1. Run the affected tests:

npm run test:php -- --filter Tests_admin_color_scheme_picker
npm run test:php -- --filter Tests_set_screen_options
npm run test:php -- --filter Tests_functions_wpGetUpdatePhpAnnotation
npm run test:php -- --filter Tests_Admin_IncludesUpdate
npm run test:php -- --filter Tests_wp_ajax_save_attachment_order
npm run test:php -- --filter Tests_wp_ajax_send_attachment_to_editor

2. Run the same filters under multisite:

npm run test:php -- -c tests/phpunit/multisite.xml --filter Tests_admin_color_scheme_picker
npm run test:php -- -c tests/phpunit/multisite.xml --filter Tests_set_screen_options
npm run test:php -- -c tests/phpunit/multisite.xml --filter Tests_functions_wpGetUpdatePhpAnnotation
npm run test:php -- -c tests/phpunit/multisite.xml --filter Tests_Admin_IncludesUpdate
npm run test:php -- -c tests/phpunit/multisite.xml --filter Tests_wp_ajax_save_attachment_order
npm run test:php -- -c tests/phpunit/multisite.xml --filter Tests_wp_ajax_send_attachment_to_editor

Two test comments incorrectly describe sanitized integer fields as numeric strings, unjustifiably retaining loose comparisons instead of using assertSame().
