Is it possible to put test_case attributes in different files and then include them?

[rockamic]

When using the test-case crate, is it possible to put the test cases in a different file and then include it? This would be to have a cleaner file.

I am currently implementing some statistical models and it is important that for a dataset it replicates the same results for each data element and so many test cases (100+) are needed and putting them all in the file would effectively clutter it.

For a simple example, is there a way to go from:

fn add_two(x: i32, y: i32) -> i32 {
    x + y
}

mod test {
    use super::*;
    use test_case::test_case;

    #[test_case(2, 2 => 4)]
    #[test_case(2, 3 => 5)]
    #[test_case(2, 1 => 3)]
    #[test_case(-2, 2 => 0)]
    fn test_add_two(x: i32, y: i32) -> i32 {
        add_two(x, y)
    }
}

To something like:

mod test {
use super::*;
use test_case::test_case;

    include!("test_cases/my_test_cases.in");
    fn test_add_two(x: i32, y: i32) -> i32 {
        add_two(x, y)
    }
}

I get the following error when attempting that:

error: expected item after attributes
 --> src/test_cases/my_test_cases.in:4:1
  |
1 | / #[test_case(2, 2 => 4)]
2 | | #[test_case(2, 3 => 5)]
3 | | #[test_case(2, 1 => 3)]
  | |_______________________- other attributes here
4 |   #[test_case(-2, 2 => 0)]

Thanks!

EDIT: fixed formatting.
