I didn't find any easy way to test this, so we'll throw the error function manually. Modify the file www/index.html to include the error reporting library like it's done in here . In the app, go to App Settings > General and check that report errors is disabled. In console, run the following command: window.onerror('Fake message for testing', 'url', 0) Check that you don't receive any email in the mobile account. Now in app settings enable the error reporting and execute the following command (please notice that the message has changed since the same error cannot be reported twice): window.onerror('Fake message for testing 2', 'url', 0) Check that you receive an email in the Mobile account.
