It's very common for Android app developers to write unit and instrumentation tests around their app. However, some bugs may still occur when the end users are using the app. Some bugs are quite hard to catch because it only happens under specific conditions that does not happen if the test is run on mock or fake data. In this talk I showed how you can use Firebase Robo Test to automate the UI testing of an Android app which allows you to test your app from end to end without using any mocking mechanism.
