Sample Coded UI Test Extension for Excel
The extension component of the sample runs in the Visual Studio Coded UI Test process and is somewhat hierarchical with the ExtensionPackage class at the base. The TechnologyManager, ActionFilter, and PropertyProvider classes are at the next level, with the control elements at the top level.
Excel Extension Architecture
These classes represent the extension points that are implemented in the sample to enable coded UI testing for Microsoft Excel.
Inherited from the UITestExtensionPackage class, this is the entry point for the coded UI testing extension. Implementing this abstract class gives the coded UI testing framework internal access to your custom UI test technology manager, UI test property provider, and UI test action filter for testing the new UI.
