How can I get the name of a test in a tokio context?

I would like the name of the test that is running.

#[traced_test]
#[tokio::test]
async fn foo() {
    assert!(true);
    println!("test name is: {}", ???);
}

How do I get the test's name?

It should also work in all functions that the test calls:

async fn bar() {
    println!("bar: test name is: {}", ???);
}
async fn foo() {
    bar().await;
}

where "bar: test name is: foo" should be printed. Or "bar: test name is: <mod>::foo".

The first option you tried working.
You just need to show output:
cargo test -- --nocapture <- this is the change

cargo.toml :

[dependencies]
tokio = {version = "1.40.0", features = ["full"]}
tracing = "0.1.40"
tracing-test = "0.2.5"

main.rs :

use tracing_test::traced_test;

#[traced_test]
#[tokio::test]
async fn foo() {
    bar();
}
fn bar() {
    let thread = std::thread::current();
    println!("{}", thread.name().unwrap());
}

// Avoid - just to cancel warnings
fn main() {
    bar();
}

Output:

test foo ... ok

successes:

---- foo stdout ----
foo


successes:
    foo

Edit for the last question edit:

use function_name::named;
use tracing_test::traced_test;
#[traced_test]
#[tokio::test]
#[named]
async fn foo() {
    let test_name = function_name!();
    println!("test name is: {}", test_name);
    assert!(true);
}

Result: test name is: foo
