Testing your app with the Windows App Certification Kit

To give your app the best chance of getting certified, validate and test it on your computer before you submit it for certification and listing in the Windows Store. Here we tell you how.

Prerequisites

• You must install and run Windows 8.

• You must install the latest version of the Windows App Certification Kit, which is included in the Windows Software Development Kit (SDK) for Windows 8.

  Note  Because it is frequently recommended that you test your app on Windows RT, be sure to also install the Windows App Certification Kit for Windows RT (available as a separate download for Windows RT devices).

• You must have a valid developer license for your computer.

• You must deploy the Windows Store app that you want to test to your computer.

  Note  If you're using Visual Studio, you can run the Windows App Certification Kit when you create your app package. See Creating an app package to learn how.

Instructions

Validate your Windows Store app by using the Windows App Certification Kit interactively

1. From the Start menu, search Apps, find Windows Kits, and click Windows App Cert Kit.

2. From the Windows App Certification Kit, select Validate a Windows Store app.

   The Windows App Certification Kit lists all the Windows Store apps that you have deployed on your computer.

3. Pick the Windows Store app you want to test, and then click Next.

   The Windows App Certification Kit begins testing the app.

4. At the prompt after the test, enter the path to the folder where you want to save the test report.

   The Windows App Certification Kit creates an HTML along with an XML report and saves it in this folder.

5. Open the report file and review the results of the test.

Validate your Windows Store app by using the Windows App Certification Kit from a command line

1. In the command window, navigate to the directory that contains the Windows App Certification Kit and run appcertui.exe.

   Note   The default path is C:\Program Files\Windows Kits\8.0\App Certification Kit.

2. From the folder that contains the Windows App Certification Kit, enter these commands in this order.

   appcert.exe reset

   appcert.exe test -apptype windowstoreapp -packagefullname [package full name] -reportoutputpath [report file name]

   where:

   [package full name] is the fully qualified name of the package.

   [report file name] is the fully qualified file name of the XML file that the kit will create to contain the test report.

3. After the test completes, open the report file named [report file name] and review the test results.

Note   For more info about the Windows App Certification Kit command line, enter the command appcert.exe /?

Remarks

Testing with a low-power computer

The performance test thresholds of the Windows App Certification Kit are based on the performance of a low-power computer.

The characteristics of the computer on which the test is performed can influence the test results. To determine if your app’s performance meets the certification requirements, we recommend that you test your app on a low-power computer, such as an Intel Atom processor-based computer with a screen resolution of 1366x768 (or higher) and a rotational hard drive (as opposed to a solid-state hard drive).

As low-power computers evolve, their performance characteristics might change over time. Refer to the most current certification requirements and test your app with the most current version of the Windows App Certification Kit to make sure that your app complies with the latest performance requirements.
