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.
