shoulds is a Shouldly-inspired test assertion library for testing Rust.
should_be
should_be_greater_than
should_be_greater_than_or_equal_to
should_be_less_than
should_be_less_than_or_equal_to
should_contain
should_not_contain
should_be_false
should_be_true
should_be_error
should_be_ok
I'll add more assertions along the way as the need arises.

}

let result = add(40, 2);

let result = concat(&"Hello, ".to_string(), &"world!".to_string());
result.should_be("Hello, world!".to_string());
