Embedded test runner experiment in Rust.
The runtime emt-rt is a crate that you add to the firmware where you implement your tests. All tests are written using the fn() signature and the device is reset before each test ie. all test functions are responsible for setting up the device.
Tests can either require human interaction or not. Those that do could for instance be tests where you need to measure a voltage on the board, press a button or similar. The runner can skip tests that require human interaction for fully automatable setups.
The runner emt is a command-line tool that leverages probe-rs to interact with the runtime. It can either run tests on a locally connected device or one hosted by another emt process.
# run all tests
# using a device connected locally
emt run
# run tests that does not require human interaction
# using a device connected locally
emt run --no-human-interaction
# host a device connected locally to be
# used by a emt runner on another machine
emt host --domain localhost --port 32100
# run all tests
# using a device hosted remotely
emt run --link hosted --domain localhost --port 32100The included example is written for the nRF52832-DK.
# flash the firmware using cargo embed
cd example
cargo embed --target thumbv7em-none-eabihf
# now run the example tests using emt
cd ..
cargo run -p emt -- run
