Only supports ARM Cortex-M semi-hosting for now.
Add embedded_test_harness and
testmacro = { git = "https://github.com/yhql/testmacro"}
to Cargo.toml dev-dependencies.
Then you may write tests following this template:
#![no_std]
#![cfg_attr(test, no_main)]
#![reexport_test_harness_main = "test_main"]
#![feature(custom_test_frameworks)]
#![test_runner(test_runner)]
use panic_semihosting as _;
#[cfg(test)]
use embedded_test_harness::test_runner;
#[cfg(test)]
mod tests {
use testmacro::test_item as test;
use embedded_test_harness::TestType;
#[test]
fn it_works() {
let result = 2 + 2;
assert_eq!(result, 4);
}
}
/// _start is the entrypoint specified in the linker
#[no_mangle]
pub fn _start() -> ! {
#[cfg(test)]
test_main();
loop {}
}
