Test mu-plugin for Trac 53566

test_trac_53566.php

<?php
/**
 * Testing for https://core.trac.wordpress.org/ticket/53566
 *
 * Tests output from _doing_it_wrong() notice in register_block_script_handle().
 *
 * To install, copy the contents of this script into a new file, e.g. test_trac_53566.php,
 *   in the `wp-content/mu-plugins/` directory. You may need to create the directory.
 * To uninstall, move or delete this file from the `wp-content/mu-plugins/` directory.
 *
 * Acceptance Criteria:
 *   Notice should contain the expected path to the missing `.asset.php` file derived from $metadata['script'].
 *   For example, `path/script-file.js` -> `path/script-file.asset.php`.
 *
 * Existing notice:
 *   The asset file for the "script" defined in "unit-tests/test-block" block definition is missing.
 *
 * Expected notice:
 *   The asset file "blocks/notice/missing-asset.asset.php" for the "script" defined in "unit-tests/test-block" block definition is missing.
