Symfony PHPUnit：无法启动会话，因为标头已发送

Question

版本：

• PHP：8.1
• PHP 单元：9.5.21
• 交响乐6.1

当 PhpUnit 运行以下测试时，我收到有关会话无法启动的错误。有谁知道这个问题以及如何解决它？

以下主题无法回答我的问题，或者建议的解决方案对我不起作用：

• 如何修复已发送的标头
• 无法发送已发送的会话 cookie 标头
• Github 讨论 43950

我尝试了第二个链接建议的解决方案：@session_start()但@runInSeparateProcess没有任何效果。也许我只是误解了我的问题，但我现在被困了一个星期。

protected function setUp(): void
{
  @session_start();
  parent::setUp();
}

/**
 * @runInSeparateProcess
 */
public function testLoginFailure(): void
{
    $client = static::createClient();
    $crawler = $client->request('GET', '/login');

    $form = $crawler->selectButton('Login')->form();

    $form['email']->setValue('bob@gmail.com');
    $form['password']->setValue('123abcABC%');

    $crawler = $client->submit($form);
    $this->assertResponseIsSuccessful();
}
