Update 1• Selenium NET Bindings and the Selenium ChromeDriver

on Visual Studio Gallery.

Working with CodedUI

• 2 ways we can work with CodedUI– Using built-in Test builder• You simply perform the test manually while the

CUIT Test Builder runs in the background• The code is generated automatically

• Hand-code– Based on “Page Object Model”• Create an Object repository• Write code manually for each object to achieve

the task

Why Hand-Coding• Generated code has

– Duplicate scripts– Repeated hardcode

• Cost lot of time to change code– Unmanaged UI control

• One control may be recorded by many times• Hand code

– More control over the code– Increase maintainability– Increase readability– Improve sustainability (reusable objects, data driven, constant

values in .settings file etc)

Page objects• Within your web app's UI there are areas that your tests

interact with. • A Page Object simply models these as objects within the test

code. • Reduce duplicated code and if changed %only be

applied in one place.

“The Page Object pattern represents the screens of your web app as a series of objects”

Interacting Objects

Microsoft.VisualStudio.TestTools.UITesting.HtmlControls

– HtmlSpan– HtmlDiv– HtmlInputButton– HtmlHyperlink– HtmlEdit

public static HtmlEdit txtStepbox(BrowserWindow browser)

{ HtmlEdit stepbox = new HtmlEdit(browser); stepbox.SearchProperties.Add(HtmlEdit.PropertyNames.Name, "_ctl0:_ctl0:orderLines:_ctl3"); return stepbox; }

– HtmlCustom

Identifying objects• Using asserting feature of CodedUI

UI Technologies for searching controls.

• Internet Explorer Testing: Uses MSHTML, DOM to retrieve properties and identify controls hosted within the Internet Explorer.

• UIA: UI Automation is the new accessibility framework for Microsoft Windows, available on all operating systems that support Windows Presentation Foundation (WPF).

• MSAA: This is picked for Winforms Controls, Win32 controls, MFC applications. All the controls that are not picked up by the above two are picked by MSAA.

CUITe• CUITe (Coded UI Test enhanced) Framework• Is a thin layer developed on top of Coded UI Test engine

which helps reduce code, increases readability & maintainability.

Feature List

– Simple to setup and use, just install and refer “CUITe.dll” in your Test project– Object Repository: Keeps UI Object definitions separate from automation code

(no more UIMaps)– Reduces code to <10%: Readable, maintainable, sustainable UI automation code– Treat table as Table (logical way of handling content inside a table)– Web Automation: JavaScript execution support– Supports Silverlight and whatever (Html & Silverlight at this point) Coded UI Test

supports underneath
