Bug report

Bug description:

import unittest class Test(unittest.TestCase): def test(self): print("hello") breakpoint() print("goodbye")

If I invoke this like:

$ python3 -m unittest -b repo.py 

Nothing is printed and the process sits waiting on input.

Whereas without the -b option we get the Pdb prompt:

$ python3 -m unittest repo.py hello > /home/matthew/code/coveragepy_issue_1963/repo.py(7)test() -> print("goodbye") (Pdb) 

I would expect that the debugger prompt would not be swallowed up by the "-b" option, or that some error message would pop up saying that the "-b" option and the debugger were incompatible.

CPython versions tested on:

3.12
