如何告诉Behat/Mink将鼠标悬停在网页上的元素上？

Question

我是Behat的新手.我目前正在使用Mink Extension和Selenium2驱动程序,我想知道如何指定测试应该作为场景的一部分悬停在元素上.

例如,这是我的场景:

Scenario: Testing that the Contact Us submenu appears
    Given I am on "/"
    When I hover over "About"
    Then I should see "Contact Us"

Answer 1

我根据这个答案/sf/answers/1205231891/找到了它,并用mouseOver()替换了click().

这是我的FeatureContext代码:

/**
 * @When /^I hover over the element "([^"]*)"$/
 */
public function iHoverOverTheElement($locator)
{
        $session = $this->getSession(); // get the mink session
        $element = $session->getPage()->find('css', $locator); // runs the actual query and returns the element

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

        // ok, let's hover it
        $element->mouseOver();
}

我必须在使用时传递css选择器,因此用法如下:

...
When I hover over the element ".about"
