Link to test case in docs instead of using doc test

I would like to keep test cases just in tests module, then in docs comments, link to specific tests relevant to the APIs. I would like to have the generated docs can redirect user to the source code of test cases by clicking the links. How can it be achieved?

/// description: ... [`test_hello`]
pub fn hello() {

mod tests {
   fn test_hello() { }

This is not possible.
