Watir - 截取屏幕截图

截取屏幕截图是 Watir 提供的有趣功能之一。在测试自动化期间，您可以截取屏幕截图并保存屏幕。如果发生任何错误，可以借助屏幕截图记录下来。

下面讨论了一个简单的示例以及我们截取屏幕截图的测试页面 −

语法

            var firstname = document.getElementById("firstname");
            
            if (firstname.value != "") {
               document.getElementById("displayfirstname").innerHTML = 
                  "The name entered is : " + firstname.value;
               
               document.getElementById("displayfirstname").style.display = "";
