Watin的Windows登录对话框

Question

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。 我应该如何处理Watin？

Answer 1

在Windows 7中，登录处理程序成为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。

下面是我们用于处理这些对话框的代码。 这是我自己写的东西，所以只要有信誉就可以随意使用。

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));

        #endregion

        #region Constructor

        public Windows7LogonDialogHandler(string username, string password)
            : base(username, password)

            _mUsername = username;
            _mPassword = password;
        }

                var lists = win.FindAll(TreeScope.Children, _mListCondition);

你可以试试这个

Browser browser = new IE();
WatiN.Core.DialogHandlers.LogonDialogHandler ldh = 
        new WatiN.Core.DialogHandlers.LogonDialogHandler("UserName","Password");
browser.DialogWatcher.Add(ldh);
browser.ShowWindow(NativeMethods.WindowShowStyle.Maximize);
browser.GoTo("http://www.yoururl.com");

但是，如果您使用的是Windows 7，则可能需要更深入地了解

我知道回答这个问题已经有很长时间了，但是尝试将这段代码与IE11一起使用时（在配置了PT-BR语言的浏览器上）遇到了一些麻烦，所以我想在这里留下我的mod给那些可能对此感兴趣或一直在挣扎的人。 *对不起，我的英语不好！
