// This test isn't testing our function -- make it do that in such a way that
// the test passes. Then write a second test that tests whether we get the result
// we expect to get when we call `is_even(5)`. Scroll down for hints!
// I AM NOT DONE

// You can call a function right where you're passing arguments to `assert!` -- so you could do
// something like `assert!(having_fun())`. If you want to check that you indeed get false, you
// can negate the result of what you're doing using `!`, like `assert!(!having_fun())`.
