Symfony 3.4升级打破了围绕预验证令牌SSO测试的PHPUnit测试

我正在将我的Symfony 2.8应用程序升级到3.4,我遇到了一些现有PHPUnit测试的问题。

这是我的 security.yml :

security:
   firewalls:
        default:
            simple_preauth:
                provider: fos_userbundle
                authenticator: appbundle.admin.tokenauthenticator

我最近升级了 friendsofsymfony/user-bundle 到 v2.1.2 作为Symfony 3.4升级的一部分。

config_test.yml (对于PHPUnit):

security:
    providers:
        appbundle.security.api.key_user_provider:
            apiusers:
                users:
                    server:
                        apikey: testUserValidRole
                        roles:
                            - 'ROLE_API_USER'

我还将PHP升级到7.2,将PHPUnit升级到7.4.3。

在我的测试中,我有:

$crawler = $client->request('POST', '/api/sso', [
    'apikey' => 'testUserValidRole',
    'site' => $site->getId(),
]);

$this->assertEquals(
     \Symfony\Component\HttpFoundation\Response::HTTP_OK,
     $client->getResponse()->getStatusCode()
);

$response = json_decode($client->getResponse()->getContent());
$this->assertTrue(isset($response->target));

$security = $client->getProfile()->getCollector('security');

// The user should only be authenticated anonymously.
$this->assertTrue($security->isAuthenticated());
$this->assertEquals(
     'Symfony\Component\Security\Core\Authentication\Token\AnonymousToken',
     $security->getTokenClass()
);

// Check that we can login with a valid loginToken.
// Note: A successful login will redirect and remove the loginToken.
$client->enableProfiler();
$crawler = $client->request('GET', $response->target);

// The user should be authenticated correctly.
$security = $client->getProfile()->getCollector('security');
$this->assertTrue($security->isAuthenticated());
$this->assertEquals(
    'Symfony\Component\Security\Core\Authentication\Token\PreAuthenticatedToken',
    $security->getTokenClass()
);

关于 PreAuthenticatedToken

断言Symfony\Component\VarDumper\Cloner\Data对象失败 &00000000 299A8BD300600690A732B预期匹配 'Symfony\Component\Security\Core\Authentication\Token\PreAuthenticatedToken'。

在Symfony升级说明中,我看不到任何关于安全性部分的内容可以指出导致此错误的原因,我必须承认,我现在对此感到有点困惑。我有一些错误的配置吗?
