 ### Scan results
-A summary of scan results will be displayed after the scan is run. In addition, an `.a11ytest` file will be generated if 1 or more errors were detected. The location of this file will be reported in the tool output (see the documentation of the `--outputDirectory` and `--scanId` parameters for ways to alter the name or location of the output file). This file can then be opened with **Accessibility Insights for Windows**, which is freely available at http://accessibilityinsights.io. If you scan an application with multiple top-level windows, an `.a11ytest` file will be generated for _each_ top-level window, even if no errors are detected.
