Rust For Typescript Devs

Unit tests

Hate them

Love them

Whatever

What matters to me is that the language has first class support for them

Lets create a test for our Rect and Circle

1. create a test in mod.rs
2. test Circle vs Circle

Complete Code

#[cfg(test)]
mod test {
    use crate::shapes::collisions::Collidable;

    use super::Circle;

    #[test]
    fn test_circle_collide() {
        let c1 = Circle {
            x: 0.0,
            y: 0.0,
            radius: 1.0,
        };

        let c2 = Circle {
            x: 1.5,
            y: 1.5,
            radius: 4.0,
        };

        assert!(!c1.collide(&c2), "expect c1 to not collide with c2");
        assert!(c2.collide(&c1), "expect c2 to collide with c1");
    }
}
