其实很简单.

1. 为测试环境设置security.yml(这是来自Symfony 2.0-RC3的片段)

1. Setup security.yml for test environment (it's a snippet from Symfony 2.0-RC3)

security:
    encoders:
        SymfonyComponentSecurityCoreUserUser: plaintext

    providers:
        in_memory:
            users:
                user:  { password: userpass, roles: [ 'ROLE_USER' ] }
                admin: { password: adminpass, roles: [ 'ROLE_ADMIN' ] }

    firewalls:
         secured-area:
             pattern:    ^/demo/secured/
             http_basic:
                 realm: "Secured Demo Area"

$client = static::createClient(array(), array(
    'PHP_AUTH_USER' => 'user',
    'PHP_AUTH_PW'   => 'userpass',
));
