UI Automation Test
UI Automation test is based on the windows API. U can find the UI Automation MSDN file from http://msdn.microsoft.com/en-us/library/ms753107.aspx link.
The important part is Using UI Automation fir Automated Testing.
As a new tester of UI Automation. I can give a demo that U can understand the UI automation better.
1st. Adding the refer reference. The reference U need add include(UIAutomation.dll, UIAutomationClientSideProvider.dll, UIAutomationTypes.dll). if U can not find these DLL U can find these in your computer C disc.
2nd. Add the using system.(System.Window.Automation).
3rd. Find the control. U must find the control which U using such as Button, textbox or label.
var desktop = AutomationElement.RootElement; // find the root element, can be consider as desktop
var condition = new PropertyCondition(AutomationElement.NameProperty, "test"); // define the string that should be find,name as "test"
var window = desktop.FindFirst(TreeScope.Children, condition); //find the desktop child control which confirm the string control
UI Automation need a tool to find the control property and the event. The tool is the UI Spy.
If U want managemet the more properties, U can use the AndContion object. Such as click the "OK" button.
var btnCondition = new AndCondition(
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button),
new PropertyCondition(AutomationElement.NameProperty, "ok"));
4th. How to trigger the control. Like Button click event, window drag event and so on. An easy example Button click:
var button = window.FindFirst(TreeScope.Children, btnCondition);
var clickPattern = (InvokePattern)button.GetCurrentPattern(InvokePattern.Pattern);
clickPattern.Invoke();
How to find the control contains which Patter? See the UI Spy.
