The timeout attribute can be used for tests to timeout after a given time. With the #[timeout] attribute a timeout in milliseconds is added to a test.

The function input must be of type int. For example #[timeout(10)] will timeout after 10 milliseconds.

Examples

This example will not panic

#[test]
#[timeout(100)]
fn no_timeout() {
    let fifty_millis = time::Duration::from_millis(50);
    thread::sleep(fifty_millis);
}

This example will panic. The function panics after 10 milliseconds

#[test]
#[timeout(10)]
#[should_panic]
fn timeout() {
    let fifty_millis = time::Duration::from_millis(50);
    thread::sleep(fifty_millis);
}
