spritz-group/QRFuzz ? reverse-engineered prompt

Build me a toolkit that helps test Android apps by generating malicious QR codes and then fuzzing them against a connected phone through Appium.

I want a simple setup where I can plug in an Android device, start Appium, create QR codes from some input data, and then run automated tests against a chosen app on the phone. The tool should save the test results in a clear folder for each app so I can review what happened after the run. If there are example configs or sample input files needed, include those too, and make it easy to extend or customize for different apps later.

Please make the experience straightforward, with clear instructions for installation and usage, and if anything depends on current docs or platform details, look them up online if needed.
