read reads from standard input by default, which is redirected to the file, so it's getting the line from the file. You can redirect back to the terminal:

read -p "Press Enter to continue" </dev/tty

Another option would be to use a different FD for the file redirection

while read -u 3
do
    ...
done 3< test.txt
