2 | 2 | """IPython Test Suite Runner. |
|
3 | 3 | |
|
4 | 4 | This module provides a main entry point to a user script to test IPython |
|
5 | 5 | itself from the command line. There are two ways of running this script: |
|
6 | 6 | |
|
7 | 7 | 1. With the syntax `iptest all`. This runs our entire test suite by |
|
8 | 8 | calling this script (with different arguments) recursively. This |
|
9 | 9 | causes modules and package to be tested in different processes, using nose |
|
10 | 10 | or trial where appropriate. |
|
11 | 11 | 2. With the regular nose syntax, like `iptest -vvs IPython`. In this form |
|
12 | 12 | the script simply calls nose, but with special command line flags and |
|
13 | 13 | plugins loaded. |
