Automated UI Testing using C1.Silverlight.Automation.dll

Let's add unit testing for the OutlookBarSamples from Silverlight Edition samples as an example.

Note: ComponentOne samples are installed, by default, in the ComponentOne Samples folder in Documents\ComponentOne Samples\Silverlight

This first step shows what we see without using the C1.Silverlight.Automation.dll.

Start the OutlookBarSamples without any modifications and explore the automation tree of the application using UI Spy or a similar tool.
The tree looks like an unorganized list of images and buttons. It does not seem to be useful for writing tests.
Add a reference to the C1.Silverlight.Automation.dll to your project.
Start the application and explore the automation tree:

Now it looks like something we can work with.
Create a test project and add to the solution.
Set up the solution:
- Set OutlookBarSamples2010Web as the startup project.
- Specify the project properties an in the following example:
Add a CodedUITest to the test project.

Write some unit tests. Find automation elements and use their patterns.
