Behat/Mink无法模拟页脚中的按钮 [英] Behat/Mink Unable to simulate click on button in footer

问题描述

对于页脚中的项目，尝试使用然后按"(对于按钮)或然后按"(对链接)正则表达式失败，错误为找不到元素/具有id | link | name的链接." 例如，我在以下公共站点上发现了这种异常:Earthdata.nasa.gov网站(我们的站点尚未激活).屏幕左侧显示反馈"的按钮不可点击(原文如此).

Attempts to use the "Then I press" (for buttons) or "Then I follow" (for links) regex for items in the footer fails with error "element/link with id|link|name was not found.. " As an example I found this anomaly on this public site: earthdata.nasa.gov site (Our site is not yet active). The button that says "feedback" on the left of the screen is not clickable (sic).

我正在对硒2.29.0服务器进行测试.如何扩展Mink，以便它可以定位并点击"链接，例如上面提到的反馈"按钮?

I am running the test against the selenium 2.29.0 server. How do I extend Mink so that it can locate and "click" on a link such as the "Feedback" button mentioned above ?

推荐答案

您可以使用XPath来单击链接，而不是使用id来单击链接. XPath是在DOM中标识对象的通用方法，因此它将始终有效.

Rather than using the id to click the link, you can use XPath to click the link. XPath is a universal way of identifying objects within the DOM, so it'll always work.

对于那些尚未使用Behat的用户，请使用此链接阅读更多内容.基本上，它是Selenium工具的包装.

For those who have who haven't used Behat, use this link to read more. It's basically a wrapper around Selenium's tools.

Ian:感谢MacGyver的指针，这里是解决方案:

Ian: Thanks to MacGyver's Pointer HERE IS THE Solution:

/** Click on the element with the provided xpath query
 *
 * @When /^I click on the element with xpath "([^"]*)"$/
 */
public function iClickOnTheElementWithXPath($xpath)
{
    $session = $this->getSession(); // get the mink session
    $element = $session->getPage()->find(
        'xpath',
        $session->getSelectorsHandler()->selectorToXpath('xpath', $xpath)
    ); // runs the actual query and returns the element

    // errors must not pass silently
    if (null === $element) {
        throw new \InvalidArgumentException(sprintf('Could not evaluate XPath: "%s"', $xpath));
    }

    // ok, let's click on it
    $element->click();

}
