Question

我试图将beforeStep()方法转换为静态方法，因为我需要在注释中使用@BeforeSuite而不是@BeforeStep。当我这样做时$this变得无法使用。我对原始代码进行了一些更改，但在下面收到错误。任何解决方案吗？

错误：

行的

self::getSession()->resizeWindow(1440, 900, 'current');

错误的

Runtime Notice: Non-static method Behat\MinkExtension\Context\RawMinkContext::getSession() should not be called statically in symfony/src/Site/CommonBundle/Features/Context/FeatureContext.php line 74

行的

self::$session->resizeWindow(1440, 900, 'current');

错误的

 PHP Fatal error:  Call to a member function getSession() on a non-object in symfony/vendor/behat/mink-extension/src/Behat/MinkExtension/Context/RawMinkContext.php on line 103

原始代码：

abstract class FeatureContext extends MinkContext implements KernelAwareInterface
{
    protected $kernel;

    /**
     * @param KernelInterface $kernelInterface Interface for getting Kernel.
     */
    public function setKernel(KernelInterface $kernelInterface)
    {
        $this->kernel = $kernelInterface;
    }

    /**
     * @BeforeStep
     */
    public function beforeStep()
    {
        $this->getSession()->resizeWindow(1440, 900, 'current');
    }

    /**
     * @Then /^I wait for "([^"]*)" seconds$/
     */
    public function iWaitForGivenSeconds($seconds)
    {
        $this->getSession()->wait($seconds*1000);
    }
}

我做了什么：

abstract class FeatureContext extends MinkContext implements KernelAwareInterface
{
    protected $kernel;
    protected static $session;

    public function __construct(array $parameters)
    {
        self::$session = $this->getSession();
    }

    /**
     * @param KernelInterface $kernelInterface Interface for getting Kernel.
     */
    public function setKernel(KernelInterface $kernelInterface)
    {
        $this->kernel = $kernelInterface;
    }

    /**
     * @BeforeSuite
     */
    public static function beforeStep()
    {
        // These won't work. First generates error 1 and second generates error 2 as shown above
        self::getSession()->resizeWindow(1440, 900, 'current');
        self::$session->resizeWindow(1440, 900, 'current');
    }

    /**
     * @Then /^I wait for "([^"]*)" seconds$/
     */
    public function iWaitForGivenSeconds($seconds)
    {
        $this->getSession()->wait($seconds*1000);
    }
}

我完全忘记了suggestion关于更改挂钩的问题。它们对你的情况毫无用处，坚持使用@BeforeScenario - 它们是最不需要静态的东西。鉴于每个方案有5-10个步骤，您已经减少了该号码的呼叫数量。不管它是不是瓶颈......

但是如果它确实消耗了一些资源，你总是可以在上下文中引入一个静态标志：

protected static $windowResized;

/**
 * @BeforeScenario
 */
public function beforeScenario()
{
    if (self::$windowResized) {
        return;
    }

    $this->getSession()->resizeWindow(1440, 900, 'current');
    self::$windowResized = true;
}

在FeatureContext中使用@BeforeStep作为静态方法
