Code Review

This pull request introduces a new PHPUnit test class, HyphensInUrlsPluginTest, to verify the behavior of the hyphens-in-urls plugin. The feedback recommends adding a tearDown method to unregister the global filter added by the plugin, ensuring proper test isolation and preventing potential test pollution in subsequent test runs.

Important

Loading the plugin file via require_once registers the ozh_hyphen_in_charset filter globally. Since PHPUnit runs tests in the same process, this filter will persist and affect subsequent tests, leading to potential test pollution and unexpected failures in other test suites.

To ensure proper test isolation, we should clean up and remove the registered filter in the tearDown() method.

    protected function setUp(): void {
        parent::setUp();
        require_once dirname( dirname( dirname( __DIR__ ) ) ) . '/user/plugins/hyphens-in-urls/plugin.php';
    }

    protected function tearDown(): void {
        yourls_remove_filter( 'get_shorturl_charset', 'ozh_hyphen_in_charset' );
        parent::tearDown();
    }
