FancyZones UI tests

UI tests are implemented using Windows Application Driver.

Before running tests

• Install Windows Application Driver v1.2.1 from https://github.com/microsoft/WinAppDriver/releases/tag/v1.2.1.
• Enable Developer Mode in Windows settings

Running tests

• Exit PowerToys if it's running
• Run WinAppDriver.exe from the installation directory. Skip this step if installed in the default directory (C:\Program Files (x86)\Windows Application Driver); in this case, it'll be launched automatically during tests.
• Open PowerToys.sln in Visual Studio and build the solution.
• Run tests in the Test Explorer (Test > Test Explorer or Ctrl+E, T).

Note: notifications or other application windows, that are shown above the window under test, can disrupt the testing process.

Extra tools and information

Test samples: https://github.com/microsoft/WinAppDriver/tree/master/Samples

While working on tests, you may need a tool that helps you to view the element's accessibility data, e.g. for finding the button to click. For this purpose, you could use AccessibilityInsights or WinAppDriver UI Recorder.

Note: close helper tools while running tests. Overlapping windows can affect test results.
