WatiN LogonDialogHandlers在Windows 7中无法正常工作

Question

我最近更新到Windows 7,VS2010和IE8.我们有一个自动化套件,使用WatiN针对IE运行测试.这些测试需要使用登录对话框处理程序,以便将不同的AD用户登录到IE浏览器中.

这在使用Windows XP和IE8时效果很好,但现在使用Windows 7导致Windows安全对话框不再被识别,对话框被忽略.这是用于启动浏览器的方法:

        public static Browser StartBrowser(string url, string username, string password)
        {
            Browser browser = new IE();
            WatiN.Core.DialogHandlers.LogonDialogHandler ldh = new WatiN.Core.DialogHandlers.LogonDialogHandler(username, password);
            browser.DialogWatcher.Add(ldh);
            browser.GoTo(url);
            return browser;
        }

任何建议或帮助将不胜感激......

无论出于何种原因,Clint发布的代码都有注释而不是输入用户名,密码和提交,并引用了一个未定义的方法,但是否则可以.这是一些已完成(和正在运行)的代码:

    public static Browser Win7Login(string username, string password, string URL) {
        Process ieProcess = Process.Start("iexplore.exe", URL);
        ieProcess.WaitForInputIdle();

        Thread.Sleep(2000);

        AutomationElement ieWindow = AutomationElement.FromHandle(ieProcess.MainWindowHandle);
        string t = ieWindow.Current.ClassName.ToString();

        Condition conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                   new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window));
        Condition List_condition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ListItem));
        Condition Edit_condition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                    new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
        Condition button_conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                     new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));

        AutomationElementCollection c = ieWindow.FindAll(TreeScope.Children, conditions);
        foreach (AutomationElement child in c) {
            if (child.Current.ClassName.ToString() == "#32770") {
                // find the list
                AutomationElementCollection lists = child.FindAll(TreeScope.Children, List_condition);
                // find the buttons
                AutomationElementCollection buttons = child.FindAll(TreeScope.Children, button_conditions);

                foreach (AutomationElement list in lists) {
                    if (list.Current.ClassName.ToString() == "UserTile") {
                        AutomationElementCollection edits = list.FindAll(TreeScope.Children, Edit_condition);
                        foreach (AutomationElement edit in edits) {
                            if (edit.Current.Name.Contains("User name")) {
                                edit.SetFocus();
                                ValuePattern usernamePattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                                usernamePattern.SetValue(username);
                            }
                            if (edit.Current.Name.Contains("Password")) {
                                edit.SetFocus();
                                ValuePattern passwordPattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                                passwordPattern.SetValue(password);
                            }
                        }
                    }
                }
                foreach (AutomationElement button in buttons) {
                    if (button.Current.AutomationId == "SubmitButton") {
                        InvokePattern submitPattern = button.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern;
                        submitPattern.Invoke();
                        break;
                    }
                }
            }
        }
        return IE.AttachTo<IE>(Find.By("hwnd", ieWindow.Current.NativeWindowHandle.ToString()), 30);
    }

这也可以像这样重构为DialogHandler:

public class Windows7LogonDialogHandler : BaseDialogHandler
{
    private readonly string _username;
    private readonly string _password;
    AndCondition _conditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                   new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window));

    readonly AndCondition _listCondition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                    new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ListItem));

    readonly AndCondition _editCondition = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));

    readonly AndCondition _buttonConditions = new AndCondition(new PropertyCondition(AutomationElement.IsEnabledProperty, true),
                                 new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));

    public Windows7LogonDialogHandler(string username, string password)
    {
        _username = username;
        _password = password;
    }

    public override bool HandleDialog(Window window)
    {
        if(CanHandleDialog(window))
        {
            var win = AutomationElement.FromHandle(window.Hwnd);
            var lists = win.FindAll(TreeScope.Children, _listCondition);
            var buttons = win.FindAll(TreeScope.Children, _buttonConditions);
            var another = (from AutomationElement list in lists
                           where list.Current.ClassName == "UserTile"
                           where list.Current.Name == "Use another account"
                           select list).First();
            another.SetFocus();

            foreach (var edit in from AutomationElement list in lists
                                 where list.Current.ClassName == "UserTile"
                                 select list.FindAll(TreeScope.Children, _editCondition)
                                     into edits
                                     from AutomationElement edit in edits
                                     select edit)
            {
                if (edit.Current.Name.Contains("User name"))
                {
                    edit.SetFocus();
                    var usernamePattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                    if (usernamePattern != null) usernamePattern.SetValue(_username);
                }
                if (edit.Current.Name.Contains("Password"))
                {
                    edit.SetFocus();
                    var passwordPattern = edit.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
                    if (passwordPattern != null) passwordPattern.SetValue(_password);
                }
            }
            foreach (var submitPattern in from AutomationElement button in buttons
                                          where button.Current.AutomationId == "SubmitButton"
                                          select button.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern)
            {
                submitPattern.Invoke();
                break;
            }
            return true;
        }
        return false;
    }

    public override bool CanHandleDialog(Window window)
    {
        return window.ClassName == "#32770";
    }
}

哪个更好一点.然后你可以像这样使用它:

using(var ie = new IE())
        {
            ie.DialogWatcher.Add(new Windows7LogonDialogHandler(@"domain\user", "password"));
            ie.GoTo("http://mysecuredwebsite");
        }

Answer 3

既然没有人回答你的问题，我会的，但不幸的是没有现成的解决方案。

我现在没有 Windows 7 可以尝试，但似乎 WatiN 的LogonDialogHandler与 Windows 7 不兼容，所以你必须编写自己的DialogHandler. 最简单的方法是继承BaseDialogHandler。您可以查看 WatiN 中现有对话框处理程序的源代码。我使自己变得非常简单，而不是处理证书对话框的通用方法。WinSpy++在实施过程中非常有用。
