Agenda

• Coded UI Test Overview

• Recording Coded UI Tests

• Adding Test Validation• Writing your own

code• Best Practices

Coded UI Test Tools

• Used to automate testing from the user interface• Test development/maintenance in Visual Studio• Tools provided to improve creation and maintenance

of Coded UI tests• Can author and maintain tests without writing code or

can extend tests using .NET• Can run within Visual Studio or through automation

(e.g., a build)

Test development and maintenance from within Visual Studio

Creating Coded UI Tests

Visual Studio (Hand Coded)

Coded UI Test

Option 1: Based on Existing Tests

• Using Microsoft Test Manager (MTM)…– Analyst defines requirements– Tester defines manual test cases for the requirement– Tester runs test cases and records the steps

• As needed, “Automation Tester” converts recorded steps into a Coded UI Test

Define Rqts

Define Tests

Capture Tests

Automate Tests

Option 2: Using the Coded UI Test Builder

• Approach:– Click the record button– Perform the steps in your test target– Click the generate code button– Repeat to generate more methods for the test– Show recorded steps to delete missteps

DEMONSTRATION

• Converting Test Cases

• Recording tests with the Coded UI Test Builder

Option 3: Author Tests using .NET

• Hand-code in .NET, without any additional assistance

• Utilize one of the Coded UI-based community frameworks:– CUITe (Coded UI Test Enhanced)

• Authored by Microsoft employees but not a ‘product’• Uses its own tooling to maintain a separate UI object repository• Improves code maintainability• Browser-based only• Currently only supported on Visual Studio 2010• Maintained on CodePlex:

http://cuite.codeplex.com/

– Code First Coded UI• Led by Microsoft employees but not a ‘product’• Pure code – does not use an object repository• Installable via NuGet• Uses Scaffolding approach to generate tests• Browser-based only• Currently only supported on Visual Studio 2010• Maintained on CodePlex:

Agenda

Tests• Adding Test Validation• Writing your own code• Best Practices

Validation

• Use the Coded UI Test Builder to add assertions

• Drag the crosshairs to a target control

• Bundle assertions into methods called from the test

Select a property

Click to add assertion

Generate a method to record the assertion(s)

DEMONSTRATION

• Adding Assertions (Verification/Validation)

The Primary Components

• Test Class (e.g., MyTest.cs)– A .NET Coded UI Test class containing one or more Test

Methods.

• Test Method– An individual automated test case inside a Test Class.

• Recorded Method– Code which actually automates the UI and performs

assertions. (Do not change this code!)

• UIMap– An XML designer file and related generated classes

containing the recorded methods.

Overriding Generated Properties

[TestMethod]public void CodedUITestMethod1(){

this.UIMap.OpenCalc();this.UIMap.AddThreeAndTwo();this.UIMap.VerifySumExpectedValues.UITxtDisplayEditText =

"5";this.UIMap.VerifySum();this.UIMap.CloseCalc();

}

“Recorded Methods” created using the UI Test Builder.

Hand-coded to change the expected value for the VerifySum recorded method. There are many other overrides made available to you in the generated code.

The API

Microsoft.VisualStudio.TestingTools.UITesting:• UITestControl

• Keyboard– SendKeys

• Mouse

• Playback.PlaybackSettings…– DelayBetweenActions– MatchExactHierarchy– SearchInMinimizedWindows– SearchTimeout– ThinkTimeMultiplier– WaitForReadyLevel– WaitForReadyTimeout

DEMONSTRATION

• UIMap Editor

Agenda

• Coded UI Test Overview

• Recording Coded UI Tests

• Adding Test Validation• Writing your own code• Best Practices

Best Practices

• Create each test case as a sequence of Recorded Methods.

• Use multiple UI Maps to separate areas o the application.

• Use meaningful test method names.

• Try to limit the length of each recorded method to less than 10 actions.

• Use meaningful UI control names in the application under test.

• Do not edit the UIMap.Designer.cs file.

• Use the Coded UI Test Builder and UI Control Locator whenever possible.
