```tldr Rust's embedded ecosystem has first-class testing support: defmt-test runs tests directly on-target with RTT output, QEMU lets you run ARM Cortex-M tests on a developer machine, and embedded-hal-mock lets you unit test peripheral drivers without hardware at all. Most embedded Rust
Embedded Testing
Real-time operating systems introduce a class of bugs that are nearly invisible in manual testing: priority inversions, stack overflows, missed deadlines, and race conditions between tasks. Most teams discover these in the field, after a product has shipped. With the right testing approach, you can catch them in CI
Embedded Testing
Waiting for physical hardware to run firmware tests is a bottleneck that slows embedded development to a crawl. Hardware is expensive, limited in quantity, and can't run in CI. QEMU emulation changes that — you can run and test ARM Cortex-M firmware on any Linux machine, including cloud
Embedded Testing
CAN bus is the backbone of automotive, industrial, and aerospace electronics. An ECU that misinterprets a single frame can disable safety-critical systems. Yet most firmware teams test their CAN implementation by plugging in a PEAK USB adapter, sending a few frames manually, and calling it done. This guide covers

```tldr Bootloader testing covers three areas: unit testing the bootloader's logic (image validation, signature verification, boot selection), integration testing in QEMU (does the bootloader actually boot the right image?), and end-to-end OTA testing (does an update succeed, and does rollback work when the new image fails?
Embedded Testing
Over-the-air firmware updates are one of the highest-risk operations an embedded device performs.
