Rust embedded testing frameworks


Hey HN, I've been developing hardware products with stm32's using Rust. I'm starting to look at tests to prevent regression issues and stabilize firmware releases but integration testing with embedded seems quite difficult.

What is currently available for embedded testing, both in the C/++ and Rust worlds? What are current industry standards surrounding this?

In the past I've seen proprietary simulators built (obviously with their own shortcomings), this would allow integration tests on simulated hardware. Are there any initiatives happening to standardize this in the Rust world?

Thanks

defmt-test is pretty cool https://github.com/knurling-rs/defmt

We built our own test framework at work, because we wanted deep ties into our entire stack.

qemu's 32-bit ARM support isn't good enough to test embedded projects successfully, in my understanding. Not enough stuff works or is accurate.
