Working on a custom android firmware has it’s own challenges, especially if you have a suite of system applications which needs UI testing. Manually, you’d need to flash your device with the custom ROM, run UI tests on it, check results. If you have a high-cadence delivery cycle, this can get troublesome, real fast. In this talk, we walk you through how we automated UI testing of our custom firmware at Hammerhead and integrated it with our CI/CD pipeline. To give a brief, with this setup, our custom hardware downloads the custom ROM, run’s tests across applications and uploads the results to the CI server - all without any human intervention.
