+Create the .env.testing file to your needs. Then once done you need to go into your phpmyadmin to create a new database named __controlpanel_test__.
 Visit http://127.0.0.1:8080/ and create your database.
 
 Now you're ready to run the following commands which switches to the testing config, migrates the test database and seeds it.
 After that you can switch back to your dev environment again. Clear the config from cache so changes will be instantly available.
 
 ```shell
+php artisan key:generate --force --env=testing
 php artisan migrate:fresh --seed --env=testing
-php artisan config:clear
 ```
 
 Now when running tests with PHPUnit it will use your testing database and not your local development one.
