"aptos move test" not running functions

[nord0711]

I am learning Move and practicing tests, but every time I run aptos move test in terminal the output is:
INCLUDING DEPENDENCY AptosFramework
INCLUDING DEPENDENCY AptosStdlib
INCLUDING DEPENDENCY MoveStdlib
BUILDING firstProject
Running Move unit tests
Test result: OK. Total tests: 0; passed: 0; failed: 0
{
"Result": "Success"
}

not actually testing anything. What is wrong with this? Here is my code for reference:

module student::demo {

use std::debug::print;

fun sample_function(){
    let uintExample : u8 = 25; 
    let boolExample =
    print(&uintExample);
}

#[test]
fun testing ()
{ 
    sample_function();
}

}

hey not sure what's going on without seeing the full code, but can you try starting from this template? https://github.com/0xaptosj/aptos-full-stack-template
