Fuchsia's Python End-to-end multi-device testing framework is located here.
This framework can be used for authoring host-driven E2E tests that interact with 1 or more Fuchsia devices. The framework can be extended to work with non Fuchsia devices as well.
This framework aims to provide a uniform test writing experience to all users and exposes conveninece methods for Fuchsia device interactions that are ergonomic and robust; with the ultimate goal of providing scriptable host-side FIDL access to a Fuchsia device-under-test.
