问题描述

我们有一个使用 WatiN 在 IE 上运行的自动化测试.此测试需要处理登录对话框.我应该如何让 Watin 处理它?<​​/p>

We have an automation test running on IE using WatiN. This test requires handling the logon dialog. How I should process it by Watin?

推荐答案

在 Windows 7 中，登录处理程序变成了 WPF 组件，不再是 IE 的一部分.我认为这甚至适用于 IE8 或更高版本.

In Windows 7, the Logon handler became a WPF component and no longer a part of the IE. I think this even applies to IE8 or higher already.

以下是我们用于处理这些对话框的代码.这是我自己写的东西，所以可以随意使用它，只要在适当的时候给予信用.

Below is the code we use for handeling these dialogs. It's something I wrote myself, so feel free to use it, as long as credit is given where due.

using System.Windows.Automation;
using System.Linq;
using WatiN.Core.DialogHandlers;
using WatiN.Core.Native.Windows;

namespace DialogHandlers
{
    public class Windows7LogonDialogHandler : LogonDialogHandler
    {
        #region Private Fields

        private readonly string _mUsername;
        private readonly string _mPassword;
        private readonly AndCondition _mListCondition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true), new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ListItem));
        private readonly AndCondition _mEditCondition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true), new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
        private readonly AndCondition _mButtonConditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true), new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));
