Calculator uses variety of automated tests, including unit tests (which test code in isolation) and UI tests (which test the finished product). Calculator has historically had a set of UI tests, but they used Microsoft-internal test frameworks and do not have coverage as extensive as we would like.

We intend to use WinAppDriver to develop a new set of UI tests for calculator. The WinAppDriver team has used Calculator as a demo application, so we'll use that code as a starting point. Once we get the initial framework checked in and running during the builds, we'll need to open additional issues to track our progress covering the desired areas of Calculator's UI.
