One-Time Setup Procedure for Using TestNav on a Chromebook

Determine if your Chromebook is managed or unmanaged. Unmanaged Chromebooks are typically only used in "bring your own device" (BYOD) settings. To check if your Chromebook is managed or unmanaged, see https://support.google.com/chrome/a/answer/1289314?hl=en&ref_topic=2935995.

For Managed Chromebooks, follow these steps:

  1. Make sure your settings for the devices being used are set to keep local data, so that SRFs and log files don't accidentally get deleted:
    1. Log into your Google Apps for Education account at http://www.google.com/enterprise/apps/education/, and log in to the Admin console for your domain.
    2. From the Admin console, select Device Management > Chrome > Device settings.
    3. In the User Data section, ensure that Do not erase all local user data is selected.
    4. Select Save changes, if visible.
  2. Enable Kiosk mode and set up TestNav on the Chromebook as a Kiosk app.
    1. Log into your Google Apps for Education account at http://www.google.com/enterprise/apps/education/, and log in to the Admin console for your domain.
    2. From the Admin console, select Device Management > Chrome > Device settings.
    3. In the Kiosk Settings section, verify that Allow Single App Kiosk is selected in the Single App Kiosk drop-down. Also, if it wasn't already visible, Manage Kiosk Applications should appear.
    4. Select Manage Kiosk Applications > Chrome Web Store. Use the Chrome Web Store Search box to search for TestNav and install.
    5. Select Add. Then select Save.
    6. Leave Auto-Login to Kiosk App set to None, and select Save changes, if visible.

See https://support.google.com/chromebook/answer/3134673?hl=en for more information about kiosk mode.

For Unmanaged Chromebooks, such as BYOD, follow these steps:

  1. If the Chromebook has never been set up with a user, skip to step 3. Otherwise, backup any important data that may be stored on the device, such as by moving items from your Downloads directory to cloud storage.
  2. Clear existing data. To clear existing data, you must switch to Developer mode and then return to Normal mode. The instructions for doing so are not the same for all Chromebooks. To find the instructions for your device, see https://support.google.com/chrome/a/answer/1360642.
  3. Enable Kiosk mode and set up TestNav on the Chromebook as a Kiosk app.
    1. Power on the Chromebook.
    2. At the Welcome! screen, select your language and keyboard. Then, connect to a network.
    3. Select Continue.
    4. On the Google Chrome OS Terms screen, select Accept and continue.
      • Critical note: do not sign in with an account until step g, after Kiosk mode has been enabled.
    5. On the Sign in screen, select the <ctrl><alt>k keys until the Enable Kiosk Mode screen appears. This may require multiple attempts before the screen appears.
    6. Select Enable, then select Ok.
    7. At the Sign in screen, enter the Email and Password for the Google account that will be used with the Chromebook, and then select Sign In.
    8. After you are logged in, you can close any windows that display.
    9. Start the Chrome browser.
    10. Enter chrome://extensions in the browser address bar. Click Enter.
    11. Select the Developer mode check box. After you select the check box, the the Add kiosk application button appears - your device is set up correctly.
      • If you do not see the Add kiosk application button, repeat steps a-c again until it does appear.
    12. Select Add kiosk application. You will be asked for the kiosk app information. Use the following:
      • ID - mdmkkicfmmkgmpkmkdikhlbggogpicma
    13. Press Enter or the Add button when ready. Note: Do not select Permanently keep this device in kiosk mode.
    14. TestNav will appear in the upper box. Select Done.
    15. Sign out of the Chromebook.

See https://support.google.com/chromebook/answer/3134673?hl=en for more information about kiosk mode.

Launching TestNav

  1. Power on the Chromebook, but do not log in.
  2. In the lower left hand of the screen, select Apps > TestNav to launch TestNav.
    A message will appear informing you that you can use <ctrl><alt>s to exit Chrome OS when you first launch TestNav. This will only work as long as the message is displayed. Once the app has started, the only way to shut down is to turn the Chromebook off, as described in the next step.
  3. To shut down, hold down the Power button to shut down and exit Kiosk mode.

Finding Your Release Version

  1. Launch the TestNav app.
  2. Focus your cursor in the username or password field.
  3. Press <ctrl><shift>z and the File Viewer box will appear. The version of the app is displayed on the second line.
  4. If the File Viewer does not display, click on the window and then press <ctrl><shift>z again.

Upgrading Your Release Version

Once TestNav has been installed from the Chrome Web Store, it should update automatically. However, if your technology environment does not allow for automatic updates via the Chrome Web Store, you may need to apply a manual update. Here is a list of the various ways that the TestNav app may be updated when a new version is released:

  1. TestNav will auto-update when TestNav is placed in Kiosk mode.
  2. TestNav will auto-update on a timeframe specified within the Chrome Web Store for non-Kiosk mode implementations.
  3. If neither of these occur, you can manually remove the outdated version of the app and install the latest version from the Chrome Web Store.

Finding Your Log Files

  1. Launch the TestNav app.
  2. Focus your cursor in the username or password field.
  3. Press <ctrl><shft>z and the File Viewer box will appear.
    If the File Viewer does not display, click on the window and then press <ctrl><shft>z again.
  4. Plug in your USB memory stick.
  5. Click the download button next to the log file(s) you wish to download.
  6. When the window opens, select the USB memory stick, and click Save.
