As per the PHP manual: > If the `component` parameter is omitted, an associative array is returned. > If the `component` parameter is specified, `parse_url()` returns a string (or an int, in the case of `PHP_URL_PORT`) instead of an array. If the requested component doesn't exist within the given URL, `null` will be returned. Reference: [https://www.php.net/manual/en/function.parse-url.php#refsect1-function.parse-url-returnvalues PHP Manual: parse_url(): Return Values] In this case, `parse_url()` is called with `PHP_URL_HOST` as `$component`, which returns `null` if the URL only has a path. The return value of `parse_url()` was then passed to `str_replace()`, leading to a notice on PHP 8.1: {{{ str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated }}} Adding validation for the return type value of `parse_url()` prevents that. This commit addresses a few errors in the test suite along the lines of: {{{ 5) Tests_Rewrite::test_url_to_postid_home_has_path str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated /var/www/src/wp-includes/rewrite.php:503 /var/www/tests/phpunit/tests/rewrite.php:271 /var/www/vendor/bin/phpunit:123 }}} Includes adding a dedicated unit test for a URL that only has a path. Follow-up to [41786], [51606], [51622], [51626], [51629], [51630], [52799]. Props jrf, aristath, poena, justinahinon, SergeyBiryukov.

The short version:
1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.
2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.
3. $ svn up
4. Run the tests from the "trunk" directory:
To execute a particular test:
$ phpunit tests/phpunit/tests/test_case.php
To execute all tests:
$ phpunit
Notes:
Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.
phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.
Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.
phpunit is intended to run at the command line, not via a web server.
