Working on a custom Android firmware has its own challenges, especially if you have a suite of system applications which need UI testing. Manually, you'd need to flash your device with the custom ROM, run UI tests on it, and check results. If you have a high-cadence delivery cycle, this can get troublesome quickly. In this talk, Nelson Osacky will walk you through how Hammerhead automated UI testing of their custom firmware at and integrated it with their CI/CD pipeline. With this setup, their custom hardware downloads the custom ROM, runs tests across applications, and uploads the results to the CI server without any human intervention.
