runner = "ostool cargo-test"
[build]
target = "aarch64-unknown-none"
```
3. setup `cargo.toml`.
```toml
[dev-dependencies]
bare-test = "0.2"
[build-dependencies]
bare-test-macros = "0.2"
[[test]]
name = "test"
harness = false
```
4. setup `build.rs`.
```rust
fn main() {
bare_test_macros::build_test_setup!();
}
```
5. new `tests` dir and add `test.rs`.
```rust
#![no_std]
#![no_main]
#![feature(used_with_arg)]
#[bare_test::tests]
mod tests {
#[test]
fn it_works() {
assert_eq!(2 + 2, 4)
}
#[test]
fn test2() {
assert_eq!(2 + 2, 4)
}
}
```
6. run `cargo test --test test -- --show-output`.
