"""IPython Test Suite Runner.
|
|
|
|
|
|
This module provides a main entry point to a user script to test IPython itself
|
|
|
from the command line. The main() routine can be used in a similar manner to
|
|
|
the ``nosetests`` script, and it takes similar arguments, but if no arguments
|
|
|
are given it defaults to testing all of IPython. This should be preferred to
|
|
|
using plain ``nosetests`` because a number of nose plugins necessary to test
|
|
|
IPython correctly are automatically configured by this code.
