Unit Tests
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn test_add() {
assert_eq!(add(2, 2), 4);
}
#[test]
#[should_panic(expected = "overflow")]
fn test_overflow() {
add(i32::MAX, 1);
}
}
Integration Tests
Place in tests/ directory (separate crate).
Property-Based Testing
use proptest::prelude::*;
proptest! {
#[test]
fn test_reverse_involutive(ref vec in prop::collection::vec(any::<i32>(), 0..100)) {
let reversed_twice: Vec<_> = vec.iter().rev().rev().cloned().collect();
assert_eq!(vec, &reversed_twice);
}
}
Review Severity
- CRITICAL: No tests for new code
- MAJOR: Missing edge case tests
- MINOR: Missing documentation on tests
