+To run PHPUnit within DDEV, we can prefix the command with `ddev exec`:
 
-If you’re not using the Symfony web server, then remove the `symfony` prefix from all of the commands below.

+## Using the PHP web server for local development
+
+If you have all of [Drupal's required PHP extensions](https://www.drupal.org/docs/system-requirements/php-requirements#extensions) installed and would like better performance (particularly on macOS), you could use the PHP's local web server.

+
+If you need to override any environment variables, you can do so before running the command:
+
+```
+$ SIMPLETEST_BASE_URL=http://localhost:8000 vendor/bin/phpunit
+```
