Update page How to Use PHP's built-in Web Server for Symfony 3.3

[jrysig]

http://symfony.com/doc/master/setup/built_in_web_server.html

Command php bin/console server:start --env=test doesn't work with Symfony 3.3.0-RC1, following error is displayed:

[Symfony\Component\Console\Exception\CommandNotFoundException] 
There are no commands defined in the "server" namespace.

The reason is a new version of AppKernel.php in Symfony Standard Edition - WebServerBundle is included only in 'dev' environment.

@JarJak But on that page we only execute the server:run command in the dev environment.
