I mean that if you run cargo test -- --nocapture on the follow code

use rstest::*;
use std::thread;

#[fixture]
pub fn testname() -> String {
    thread::current().name().unwrap().to_string()
}

#[rstest]
#[case("my_test")]
#[should_panic]
#[case("something_else")]
fn my_test(testname: String, #[case] v: &str) {
    assert!(dbg!(testname).contains(v));
}

You'll see the follow output
