Answer 1

通过更新findElement方法的参数值来尝试以下代码：

 //Find the main menu element
    WebElement menu = driver.findElement(By.id("top_sell"));

    //Perform mouse over action
    Actions mouseMenu = new Actions(driver);
    mouseMenu.moveToElement(menu).build().perform();

    //Then find the sub menu element
    WebElement subMenu = driver.findElement(By.cssSelector("a[href='/some_link'"));

    //Now click on sub menu
    subMenu.click();
