要从上下文菜单中选择项目，您只需使用按键向下事件移动鼠标位置，如下所示： -

To select the item from the contextual menu, you have to just move your mouse positions with the use of Key down event like this:-

Actions action= new Actions(driver);
action.contextClick(productLink).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.RETURN).build().perform();

希望这对你有用。
祝你有美好的一天：）
