Using the Windows App Certification Kit

Applies to Windows and Windows Phone

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. This topic shows you how to install and run the Windows App Certification Kit. For more details on specific tests carried out by this kit, including new Windows 10 tests shipping with the developer tools for Windows Insider Preview, refer to the following topics:

For a high level look at the certification process, and where the use of this tool fits in, see Certify your app.

Prerequisites

If you are developing a Windows 8 app:

If you are developing a Windows 8.1 app:

  • You must install and run Windows 8.1 or Windows 10 Insider Preview.

  • You must install Windows App Certification Kit version 10, which is included in the Windows Software Development Kit (SDK) for Windows 10.

If you are developing a Windows Phone 8.1 app:

If you are developing a Windows 10 Insider Preview app:

  • You must install the Windows 10 Insider Preview Technical Preview.
  • You must install Windows App Certification Kit version 10, which is included in the Windows SDK for Windows 10.

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).

To run Windows App Certification Kit version 10 on a Windows RT machine (Windows 8.1 RT), the kits policy needs to be installed as well. For details on installing the kits policy, see ARM Kit Policy Installation.

Other pre-requisites:

  • You must have a valid developer license for your computer. See Get a developer license to learn how.

  • 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.

Enabling in place upgrade

The installation of Windows App Certification Kit version 10 or higher will replace any previous version of the kit that is installed on the machine.

Instructions

Validate your Windows Store app or Windows Phone 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 the category of validation you would like to perform. For example: If you are validating a Windows Store app, select Validate a Windows Store app.

    You may browse directly to the app you're testing, or choose the app from a list in the UI. When the Windows App Certification Kit is run for the first time, the UI lists all the Windows Store apps that you have installed on your computer. For any subsequent runs, the UI will display the most recent Windows Store apps and Windows Phone apps that you have validated. If the app that you want to test is not listed, you can click on My app isn't listed to get a comprehensive list of all apps installed on your system.

  3. After you have input or selected the app that you want to test, click Next.

  4. From the next screen, you will see the test workflow that aligns to the app type you are testing. If a test is grayed out in the list, the test is not applicable to your environment. For example, if you are testing a Windows 10 app on Windows 7, only static tests will apply to the workflow. Note that the Windows Store may apply all tests from this workflow. Select the tests you want to run and click Next.

    The Windows App Certification Kit begins validating the app.

  5. 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.

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

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

Important  The Windows App Certification Kit must be run within the context of an active user session.
  1. In the command window, navigate to the directory that contains the Windows App Certification Kit.

    Note   The default path is C:\Program Files\Windows Kits\10\App Certification Kit\.
  2. Enter the following commands in this order to test an app that is already installed on your test computer:

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

    Or you can use the following commands if the app is not installed. The Windows App Certification Kit will open the package and apply the appropriate test workflow:

    appcert.exe reset
    appcert.exe test -appxpack- agepath [package path] -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, that includes the file path, of the XML file that the kit will create to contain the test report.

    [package path] is the full path to the package.

    You will no longer need to specify windowsstoreapp or windowsphoneapp for the -apptype parameter, because the app type is automatically determined by the kit.

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

Note  The Windows App Certification Kit can be run from a service, but the service must initiate the kit process within an active user session and cannot be run in Session0. For more information on this test scenario, download the Windows App Certification Kit white paper.

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 Windows and Windows Phone Store Policies, 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 Windows and Windows Phone Store Policies 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.
