问题描述

请访问此网站.

单击登录"后，我具有此用户凭据表单，并尝试在缺少Email Address或Password的情况下登录后，收到以下消息:

After click log in i have this User credentials form and after try to login with missing Email Address or Password i got this message:

因此，我尝试通过打印所有页面HTML(driver.getPageSource())找到该元素，但是缺少此文本.

So i try to find this element by print all the page HTML (driver.getPageSource()) but this text is missing.

任何想法如何验证我有这个error message吗?

Any idea how to verify that i have this error message ?

推荐答案

验证消息不是DOM的一部分.之所以生成它们，是因为您的输入文件具有required属性.如果您看到字段的HTML-

The validation messages are not the part of your DOM. They are generated because your input fileds have required attribute. If you see the HTML of your fields -

<input type="text" placeholder="Enter Username" name="uname" required="">

您可以看到它已打开必填属性.检查此.您可以验证您的字段是否具有此必填属性，例如-

You can see it has required attribute turned on. Check this out. You can verify that your fields have this required attribute or not, like this-

WebElement inputElement = driver.findElement(By.name("uname"));
JavascriptExecutor js = (JavascriptExecutor) driver;  
boolean isRequired = (Boolean) js.executeScript("return arguments[0].required;",inputElement)
if(isRequired )
{
   //element is required and validation error will popup if the field is empty.
}

无需担心消息是否出现，因为这将由浏览器处理.

There is no need to care about whether the message appears or not because that will handled by the browser.
