Testing Support

The DevExpress Universal Subscription includes built-in support for Microsoft's CodedUI. Unlike many vendors claiming support for Coded UI through the simple use of MSAA, DevExpress controls go the extra mile to make certain that individual controls fully comply with Microsoft's testing framework. We don't simply support Coded UI; we support it to the maximum extent possible. Note: CodedUI support requires purchase of the DevExpress Universal Subscription. Learn more

The DevExpress MVVM Framework ships with features that are absent in WinForms, but essential to MVVM development. These missing features include bindings, commands, UI triggers, behaviors etc. Our Framework includes all of these along with a straightforward API to make WinForms app development more efficient.
