For anyone still looking for potential solutions, I’m just finishing the beta version of a way to quickly do an E2E “smoke test” by uploading the apk/ipa, no appium setup or writing tests. It’s android only at the moment with iOS coming soon: https://www.smoketest.ai
It uses Appium and attempts to crawl your app and hit as much functionality as it can, then return test results and video. It also works with AWS Device Farm, but I haven’t enabled that option as it costs money to run. If anyone is interested, I’m happy to offer a free account and even write custom tests for you in exchange for feedback to improve it.
