trezor-firmware/tests/input_flows.py

"""
Central place for defining all input flows for the device tests.

Each model has potentially its own input flow, and in most cases
we need to distinguish between them. Doing it at one place
offers a better overview of the differences and makes it easier
to maintain. The whole `device_tests` folder can then focus
only on the actual tests and data-assertions, not on the lower-level
input flow details.
