Selenium WebDriver-意外的模式对话框警报 [英] Selenium WebDriver - Unexpected modal dialog Alert
问题描述
我正在尝试使用WebDriver来自动化网站. 我正在使用Firefox驱动程序,但是主页上有一个弹出模式警报窗口:说:
I am trying to use WebDriver to automate an website. I am using Firefox Driver, but the homepage has a Pop-up modal alert window: saying:
您需要使用IE 6.0来查看此应用程序.其他一些 功能可能不起作用 我检查了页面的来源,它有一个功能. Modal Alert不是HTML元素,我尝试使用FireBug查找任何元素,但无济于事.
You need to use IE 6.0 for viewing this application. Else some features may not work I checked the Source of the page, it has a function. The Modal Alert is not an HTML element, I tried finding any element with FireBug, but to no avail.
if ( strBrowName == "Microsoft Internet Explorer" )
{
if ( (( strBrowVersion.indexOf( 'MSIE 6' ) ) > 0 ) )
{
}
else
{
alert( "You need to use IE 6.0 for viewing this application. Else some features may not work" );
}
在我的WebDriver代码中,我在驱动程序中使用了以下功能(如此处其他文章所建议的那样)
In my WebDriver code I am using the following capability in the Driver (as suggested by some other post here)
DesiredCapabilities dc=new DesiredCapabilities();
dc.setCapability(CapabilityType.UNEXPECTED_ALERT_BEHAVIOUR,UnexpectedAlertBehaviour.ACCEPT);
WebDriver driver =new FirefoxDriver(dc);
然后我在try-catch中进行了一个简单的get调用:
Then I am making a simple get call, enclosed in a try-catch:
try {
driver.get(B);
}
catch (UnhandledAlertException e) {
System.err.println("Caught UnhandledAlertException: ");
}
System.out.println("URL Opened");
如果我没有在驱动程序对象上编写任何方法,而是关闭驱动程序. 该程序通常会在Eclipse中终止,但是尽管存在以下情况,但Modal Alert仍保持打开状态:
If I do not write any method on the driver object and close the driver instead. The program terminates in Eclipse normally, but the Modal Alert stays open, inspite of the:
UnexpectedAlertBehaviour.ACCEPT
但是,如果我使用任何与驱动程序相关的方法或操作,就像getTitle一样简单:
But, if I use ANY driver related method or operation, like, as simple as getTitle:
String title = driver.getTitle();
Java代码失败并显示Exception,但是模式Alert弹出窗口关闭! 错误的最后一行被指定为我使用的行 第一个与驱动程序相关的操作.
The Java code fails with Exception, BUT the modal Alert pop-up closes! And the last line number of the error is given as the line where I used the first driver related operation.

推荐答案
该行为是预期的.它是这样工作的-
The behaviour is intended. Here is how it works -
- 您发出driver.get(B).它触发浏览器打开网页,然后与浏览器没有任何关系,因此它不在乎警报是否打开.
- 页面加载后,会弹出一个对话框,但是在代码端或Eclipse上什么也没有发生.
- 当您尝试执行其他操作时,它会与浏览器交互并看到意外的弹出对话框.
现在,出现模式对话框关闭且仍然发生异常的问题,因此请尝试以下操作.
Now, the problem occurs that modal dialog closes and still exception occurs, so try the following.
- 在try/catch中包含第二个操作,并处理 UnhandledAlertException
- 在该catch块内,执行驱动程序->切换至->警报->接受
- 在catch块之后,再次执行第二个操作.
