Your IDE needs to run your program in a terminal emulation for that.

If that's not possible you may consider hacking a special test mode.

Redirecting STDIN/STDOUT to a console/terminal subprocess, while keeping STDERR and process control inside your IDE's mainprocess.

I think (?) I did this in the past from within Emacs, but I can't find it anymore.

Hope I gave you enough feedback for further research on the matter.
