Symfony 2 BDD Behat 上下文 "I am not logged in"

Question

在 BDD Behat 场景中，如何手动确保用户未登录我的 FeatureContext 类？例如我有这个场景:

Scenario: passing wrong values will not get me in
Given I am on "/login"
And I am not logged in
When I fill in "login" with "KtokolwiekWidzialKtokolwiekWie"
When I fill in "password" with "root_as_allways"
When I press "Login"
Then I should be on "/"
And I should see "Wrong login or password"

我已经定义了这个上下文:

/**
 * @Given /^I am not logged in$/
 */
public function iAmNotLoggedIn()
{
    # logout currently login user, if any
    $request = $this->kernel->getContainer()->get('request');
    $request->getSession()->invalidate();
}

但这在运行此功能测试时会给我一个错误。

You cannot create a service ("request") of an inactive scope ("request").

注意:我使用的是 Symfony 2.1 RC-1

这是您可以使用的自定义步骤:

/**
 * @Given /^I am not logged in$/
 */
public function iAmNotLoggedIn()
{
    $this->getMink()
        ->getSession()
        ->visit($this->locatePath('/logout'))
    ;
}

但您可能需要更新您的步骤顺序:

Given I am not logged in
  And I am on "/login"
