In a scenario where a mobile app must work seamlessly on both Android and iOS, what key factors should be considered in the automation strategy?

When aiming for seamless functionality on both Android and iOS, using cross-platform testing frameworks is essential. These frameworks enable the creation of test scripts that can be executed on both platforms, streamlining the automation process. Emulator and simulator usage is crucial for simulating device environments, and considering device fragmentation ensures coverage across various devices and versions. Carefully choosing the right mix of factors is vital for a robust automation strategy in a cross-platform scenario.
