Example
fn to_test(output: bool) -> bool {
output
}
#[cfg(test)] // The module is only compiled when testing.
mod test {
use super::to_test;
// This function is a test function. It will be executed and
// the test will succeed if the function exits cleanly.
#[test]
fn test_to_test_ok() {
assert_eq!(to_test(true), true);
}
// That test on the other hand will only succeed when the function
// panics.
#[test]
#[should_panic]
fn test_to_test_fail() {
assert_eq!(to_test(true), false);
}
}
Run with cargo test.
