在 FeatureContext 中访问 symfony 参数

Question

如何在 FeatureContext.php 中访问 symfony 参数（例如 parameters.yml）？

如果我在任何控制器中使用$this->getContainer()->getParameter('currency');，我可以获得值并且我想对FeatureContext 做同样的事情，那么我怎样才能使下面的代码成为可能？

提前致谢

我想让这个示例以某种方式工作：

namespace Football\TeamBundle\Features\Context;

use Behat\MinkExtension\Context\MinkContext;

class FeatureContext extends MinkContext
{
    /**
     * @Then /^I print currency$/
     */
    public function iSeeCurrency()
    {
        echo $this->getContainer()->getParameter('currency');
        sleep(60);
    }
}

仅供参考；我的这个例子可以很好地访问 symfony 服务：

use Behat\MinkExtension\Context\MinkContext;
use Behat\Symfony2Extension\Context\KernelDictionary;

class FeatureContext extends MinkContext
{
    private $kernel;
    use KernelDictionary;

    public function setKernel($kernel)
    {
        $this->kernel = $kernel;
    }

    /**
     * @Then /^I want to say hello to "([^"]*)"$/
     * @param $seconds
     */
    public function iSayHello($name)
    {
        $container = $this->getContainer();
        $behatService = $container->get('behat_service');

        echo $behatService->sayHello($name);
        sleep(60);
    }
}

配置文件：（我也有 _dev.yml 和 _prod.yml 环境）

config.yml

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: globals.yml }

config_test.yml

imports:
    - { resource: config.yml }
    - { resource: parameters_test.yml }

parameters_test.yml

parameters:
    database_driver: pdo_mysql
    database_host: 127.0.0.1
    database_port: null
    database_name: symfony_test
    database_user: root
    database_password: root

globals.yml

parameters:
    currency: EUR.USD.GBP

专题背景

use Behat\MinkExtension\Context\MinkContext;
use Behat\Symfony2Extension\Context\KernelDictionary;

class FeatureContext extends MinkContext
{
    private $kernel;
    use KernelDictionary;

    public function setKernel($kernel)
    {
        $this->kernel = $kernel;
    }

    /**
     * @Then /^I access only currency parameter$/
     */
    public function printCurrency()
    {
        $container = $this->getContainer();
        echo $container->getParameter('currency');
    }
}
