如何在Firefox 19中使用Selenium WebDriver进行鼠标悬停？

使用动作对象，您应该首先移动菜单标题，然后移至弹出菜单项并单击它。不要忘记

actions.perform()

Actions actions = new Actions(driver);WebElement menuHoverlink = driver.findElement(By.linkText("Menu heading"));actions.moveToElement(menuHoverlink);WebElement sublink = driver.findElement(By.cssSelector("#headerMenu .sublink"));actions.moveToElement(sublink);actions.click();actions.perform();
