自动化测试（二）

实例1：找到已知名称的窗口

AutomationElement desktop = AutomationElement.RootElement;
string wndName="XXX";
Wnd = desktop.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty,wndName));

实例2：找到窗口中一个显示为“开始”的文本Label

string ControlName="开始";
            var lbStart = Wnd.FindFirst(TreeScope.Descendants, new AndCondition(new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Text),new PropertyCondition(AutomationElement.NameProperty,ControlName)));

实例3：有一个id为calendar的ComboBox，选择其中的July项

            string ComboItemName = "July";
            //找到id为calendar的ComboBox
            AutomationElement calendar = Wnd.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.AutomationIdProperty, "calendar"));
            
            //展开
            ExpandCollapsePattern ecPattern = (ExpandCollapsePattern)calendar.GetCurrentPattern(ExpandCollapsePattern.Pattern);
            ecPattern.Expand();

            //找到名称为July的项
            var typeCond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ListItem);
            
            AutomationElementCollection items = calendar.FindAll(TreeScope.Descendants, typeCond);
            AutomationElement itemToSelect = items[6];

            Object selectPattern = null;
            if (itemToSelect.TryGetCurrentPattern(SelectionItemPattern.Pattern, out selectPattern))
            {
                ((SelectionItemPattern)selectPattern).Select();
            }

 实例4：点击一个无法Invoke的控件

首先导入win32 api

        [DllImport("user32.dll", EntryPoint = "SetCursorPos")]
        public static extern int SetCursorPos(int x, int y);


        [DllImport("user32.dll", EntryPoint = "ShowWindow", CharSet = CharSet.Auto)]
        public static extern int ShowWindow(IntPtr hwnd, int nCmdShow);


        [DllImport("user32.dll", EntryPoint = "SetForegroundWindow", SetLastError = true)]
        public static extern void SetForegroundWindow(IntPtr hwnd);


        [DllImport("user32.dll")]
        public static extern void mouse_event(uint dwFlags, int dx, int dy, uint dwData, UIntPtr dwExtraInfo);

            var itemSeq = Wnd.FindFirst(TreeScope.Descendants, new AndCondition(c1, c2));
            if (itemSeq == null)
            {
                MessageBox.Show("No ListItem序列found");
            }else
            {
                System.Windows.Point p=new Point();
                WindowsApi.SetForegroundWindow((IntPtr)Wnd.Current.NativeWindowHandle);
                WindowsApi.ShowWindow((IntPtr)Wnd.Current.NativeWindowHandle, 3);
                if (itemSeq.TryGetClickablePoint(out p))
                {
                    WindowsApi.SetCursorPos((int)p.X, (int)p.Y);
                    WindowsApi.mouse_event(WindowsApi.MOUSEEVENTF_LEFTDOWN | WindowsApi.MOUSEEVENTF_LEFTUP, 0, 0, 0, (UIntPtr)0);

                }

            }

ShowWindow的参数 1，表示常规，2表示最小化，3表示最大化。

通过SetCursorPos和mouse_event的方法，还可参考https://www.cnblogs.com/T-ARF/archive/2004/01/13/12172997.html

实例5：向文本框发送回车键

box = Wnd.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.AutomationIdProperty, "textBox2"));

WindowsApi.SetForegroundWindow((IntPtr)Wnd.Current.NativeWindowHandle);
box.SetFocus();
SendKeys.SendWait("{ENTER}");

实例6：向文本框发送回车键  方法2

            WindowsApi.SetForegroundWindow((IntPtr)Wnd.Current.NativeWindowHandle);
            box.SetFocus();
            WindowsApi.PostMessage((IntPtr)box.Current.NativeWindowHandle, 0x0100, 0x0D, 0);

导入win32 api

    [DllImport("user32.dll")]
    static extern bool PostMessage(IntPtr hWnd, UInt32 Msg, int wParam, int lParam);

0x0100表示WM_KEYDOWN，0x0D表示回车键，完整列表http://www.kbdedit.com/manual/low_level_vk_list.html
