Behat/Mink switchToIframe 错误异常：无效参数：'id' 不能是字符串

Question

我在 Drupal 站点中使用 Behat/Mink/Selenium 和 ChromeDriver 将输入数据设置到 Braintree 托管字段 iFrame 中，但我收到错误：异常：无效参数：'id' 不能是字符串。 Github 上有一个类似的问题，但没有答案： https://github.com/minkphp/MinkSelenium2Driver/issues/315

FeatureContext.php：

<?php

use Behat\Behat\Tester\Exception\PendingException;
use Behat\Behat\Context\Context;
use Drupal\DrupalExtension\Context\MinkContext;


/**
 * Defines application features from the specific context.
 */
class FeatureContext extends MinkContext {
  /**
   * Initializes context.
   *
   * Every scenario gets its own context instance.
   * You can also pass arbitrary arguments to the
   * context constructor through behat.yml.
   */
  public function __construct() {
  }

  /**
   * @When I fill in cardnumber :arg1 with :arg2
   */
  public function iFillInCardnumberWith($arg1, $arg2) {
    $this->getSession()
      ->getDriver()
      ->switchToIFrame('braintree-hosted-field-number');

    $page = $this->getSession()->getPage();

    $InputField = $page->findField($arg1); 
    $InputField->setValue($arg2);

    $this->getSession()->getDriver()->switchToIFrame(NULL);
  }

}

在我的功能中：

我在卡号“信用卡号”中填写“4111111111111111”

全部错误：

Answer 1

我对这个 Docker 映像 selenium/standalone-chrome-debug 也有同样的问题，即没有版本号，所以我假设是“最新的”。当我使用 selenium/standalone-chrome-debug:3.141.59-neon 时，一切都很好。

Answer 2

我认为错误在于您的$arg1 输入值。给定：

$page->findField($arg1)->setValue($arg2);

你能把输入改成：

And I fill in cardnumber "cardnumber" with "4111111111111111"

其中"cardnumber" 是您的卡号输入元素的名称属性。另见Behat/Mink doesn't find field by id。

丢弃该值的输入并仅对该名称属性进行硬编码可能会更好（除非我怀疑它会发生变化？）：

$this->getSession()->getPage()->findField('cardnumber')->setValue($card);
