Android Emulator Containers streamline Android app testing by eliminating the complexities arising from OS compatibility issues and system dependencies as well as from setting up emulators for multiple Android versions. Traditionally, this complexity led to extra effort or teams foregoing automated testing completely, which, in turn, resulted in slower development and testing cycles. Android Emulator Containers simplify this process, allowing seamless integration into CI pipelines for automated testing. Our teams utilize these containers primarily for instrumented tests, which are automatically executed with each commit to provide instantaneous feedback to developers. Additionally, we leverage Android Emulator Containers for running nightly end-to-end tests as well.
