Create sub module with tests for multiple input data

Examples

#[cfg(test)]
mod tests {
    use data_test::data_test;
 
    #[test]
    fn it_works() {
        assert_eq!(2 + 2, 4);
    }
 
    data_test!{
        fn is_equal(input, expected) => {
            assert_eq!(input, expected);
        }
        - a (1, 1)
        - b (2, 2)
        - c (3, 3)
        - d (4, 4)
        - e (5, 5)
        - f ("hello world", "hello world")
    }
