|
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 |
