Pytest Tests in Twister
summary
A pytest plugin for Twister lets tests use pytest fixtures and plugins while Twister handles collection and reporting via JUnit XML, enabling device-type agnostic tests that run on hardware, QEMU or native posix. Implemented device adapters abstract serial/FIFO details, fixtures manage setup/teardown and scopes, and examples include interactive shell checks, an MCUboot downgrade prevention flow using mcumgr, and a full LwM2M end-to-end interoperability test that spins up a Leshan server in Docker and verifies live client-server exchanges.
