Writing Automated Tests

Testing in Oxide follows Rust's model: you write test functions annotated with #[test] and run them with cargo test. Assertions are provided by the standard library.

What You'll Learn

• How to write and run tests
• How to organize tests within a crate
• How to use common assertions

A Small Example

fn addTwo(value: Int): Int {
    value + 2
}

#[test]
fn addsTwo() {
    let result = addTwo(40)
    assertEq!(result, 42)
}
