Better late than never. I've imported Shravan's work-in-progress cordova-app-harness work into the Apache repo.
The instructions for running it are in the README.md. They are fairly long since they require cordova-CLI's future branch. Shravan's task list for the week: AppHarness: App re-download button to menu AppHarness: Able to uninstall an app AppHarness: Page Refresh button to menu AppHarness: Create a script that will make a harness-compatible .zip file of a Cordova app AppHarness: Parse config.xml to get start page. AppHarness: Code clean-up for context menu AppHarenss: Delete directory before installing. One thing I know he was hoping to get help with (aka for someone else to do) is the URL via QR code scanning.
