"""IPython Test Suite Runner.
|
|
|
|
|
|
This module provides a main entry point to a user script to test IPython
|
|
|
itself from the command line. There are two ways of running this script:
|
|
|
|
|
|
1. With the syntax `iptest all`. This runs our entire test suite by
|
|
|
calling this script (with different arguments) recursively. This
|
|
|
causes modules and package to be tested in different processes, using nose
|
|
|
or trial where appropriate.
|
|
|
2. With the regular nose syntax, like `iptest -vvs IPython`. In this form
|
|
|
the script simply calls nose, but with special command line flags and
|
|
|
plugins loaded.
