Seems to be a CW problem: please report it at [https://github.com/Codewars/codewars.com/issues](the official github repo).

Meanwhile, the initial code and sample tests are:

fn get_age(age: &str) -> u32 {
  // Your code here
}

#[test]
fn basic_tests() {
  assert_eq!(get_age("0 years old"), 0);
  assert_eq!(get_age("2 years old"), 2);
  assert_eq!(get_age("4 years old"), 4);
  assert_eq!(get_age("5 years old"), 5);
  assert_eq!(get_age("7 years old"), 7);
}

Thanks again! Approved. Have a good day.

Thanks! Good job but "actual" and "expected" are not in the same position for fixed tests and random tests. Which is the good one? Random tests?

Do you feel like implementing real random tests for that kata?

No random tests for Rust: CW has not implemented the crate random for Rust because it causes problems.
Nevertheless the Rust translator has put a few ones even if they are not completely random.

I think you could read again the description:

Ranks are numbered from 1, not firstnames or names length.

There are no error in the tests, 729 guys passed the kata (81 with C#) as you can see at the top of the page.

It looks like Souzooka was able to make this change. Let me know if you're not seeing it. Thank you!

Hi, yes, you're right. I forgot to change the sample tests before publishing, so that's my bad.

I think the Kata author may have to manually change the sample tests at this point.
