+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](https://accessibilityinsights.io/docs/windows/overview) or [WinAppDriver UI Recorder](https://github.com/microsoft/WinAppDriver/wiki/WinAppDriver-UI-Recorder).
 
+>Note: close helper tools while running tests. Overlapping windows can affect test results.
