Test du code
Hello pour tester du code on evite de faire un main par fichier on utile le mod tests
qui est un
peu magique.
Tutoriel sur le sujet: https://doc.rust-lang.org/stable/rust-by-example/testing/unit_testing.html Petit extrait du tutoriel:
pub fn add(a: i32, b: i32) -> i32 {
a + b
}
// This is a really bad adding function, its purpose is to fail in this
// example.
#[allow(dead_code)]
fn bad_add(a: i32, b: i32) -> i32 {
a - b
}
#[cfg(test)]
mod tests {
// Note this useful idiom: importing names from outer (for mod tests) scope.
use super::*; // ça importe donc bad_add :)
#[test]
fn test_add() {
assert_eq!(add(1, 2), 3);
}
#[test]
fn test_bad_add() {
// This assert would fire and test will fail.
// Please note, that private functions can be tested too!
assert_eq!(bad_add(1, 2), 3);
}
}
