We can also see that we must import the function, as it is super to the module. Inside this module, we can run standard tests that check to see whether the integers we pass in calculate the Fibonacci number we expect with the following code: #[test]

fn test_one() {

assert_eq!(fibonacci_number(1), 1);

}

#[test]

fn test_two() {

assert_eq!(fibonacci_number(2), 1);

}

#[test]

fn test_three() {

assert_eq!(fibonacci_number(3), 2);

}

#[test]

fn test_twenty() {

assert_eq!(fibonacci_number(20), 6765);

}

Here, we can see that we have decorated our test functions with the #[test] macro. If they do not produce the results that we expect, then assert_eq! and the test will fail. We also must note that our function will panic if we pass in zero or a negative value.
