Echo output to terminal within function in BASH

Question

I am writing a script in BASH. I have a function within the script that I want to provide progress feedback to the user. Only problem is that the echo command does not print

Answer 1

Yet a solution other than sending to STDERR (it may be preferred if your STDERR has other uses, or possibly be redirected by the caller)

This solution direct prints to the terminal tty:

function test_function {
    echo "Echo value to terminal" > /dev/tty
    echo "return value"
}
