more documentation for interactive commands

In this case, is 'kbond' what is typed in on the CLI when create:user is run? As opposed to being the arguments?

        $this->executeConsoleCommand('create:user', ['kbond'])
            ->assertSuccessful()
            ->assertOutputContains('Creating regular user "kbond"')
        ;

I'm not sure how adding the --no-interaction works.

        // advanced testing interactive commands
        $this->consoleCommand(CreateUserCommand::class)
            ->addInput('kbond')
            ->addOption('--no-interaction') // commands are run interactively if input is provided, use this option to disable
            ->execute()
            ->assertSuccessful()
            ->assertOutputContains('Creating regular user "kbond"')
        ;

I guess I'm looking for a way to test interactive loops, like a command that asks for an email and role, throwing a message if the email already exists.

bin/console add:users

enter email>
abc@def.com
new email!  enter role>
ROLE_USER
@abc@def added with ROLE_USER
enter email>
xyz@def.com
new email!  enter role>
ROLE_ADMIN
@xyz@def added with ROLE_ADMIN
enter email>
abc@def.com
abc@def exists.  enter role>
ROLE_ADMIN
abc@def updated to ROLE_ADMIN
enter email>

Success.

Agreed, this could be improved - I never write interactive commands so didn't fully think this part out.
