debugging - Exiting Python Debugger ipdb

Question

I use ipdb fairly often in a way to just jump to a piece of code that is isolated i.e. it is hard to write a real script that uses it. Instead I write a minimal test case with mocking and jump into it.

Exemplary for the workflow:

def func():
   ...
   import ipdb
   ipdb.set_trace()
   ...

def test_case():
    ...
    func()
    ...

Then, invoke

py.test test_file.py -s -k test_case

Now, usually I just check one variable or two, and then want to quit. Change the code and do it over again.

How do I quit? The manual says q quits the debugger. It doesn't (really). You have to quit a few times before the debugger actually terminates. The same behavior for Ctrl-C and Ctrl-D (with the additional frustration that hitting Ctrl-D several times eventually quits the terminal, too).

Is there a smart way to force quit? Is this workflow even sensible? What is the standard way to do it?

Answer 1

The following worked for me:

import sys
sys.exit()

On newer versions of ipython, as mentioned above and below, this doesn't work. In that case,

import os
os._exit(0)

should still do the trick.
