Property based testing

Property based testing using the proptest crate

The proptest library works well together with test-r. There is no special requirements, just make sure to import test-r's test attribute before using the proptest! macro to define the property based tests.

For example:

#![allow(unused)]
fn main() {
use test_r::test;
use proptest::prelude::*;

fn parse_date(s: &str) -> Option<(u32, u32, u32)> {
    todo!()
}

proptest! {
    #[test]
    fn parses_all_valid_dates(s in "[0-9]{4}-[0-9]{2}-[0-9]{2}") {
        parse_date(&s);
    }
}
}
