Running unit tests with Nose inside a Python envir

问题:

I'd like to start creating unit tests for my Maya scripts. These scripts must be run inside the Maya environment and rely on the maya.cmds module namespace.

How can I run Nose tests from inside a running environment such as Maya?

回答1:

Use the mayapy executable included in your maya install instead of the standard python executable.

In order for this work you'll need to run nose programmatically. Create a python file called runtests.py and put it next to your test files. In it, include the following code:

import os
os.environ['PYTHONPATH'] = '/path/to/site-packages'

import nose
nose.run()

Since mayapy loads its own pythonpath, it doesn't know about the site-packages directory where nose is. os.environ is used to set this manually inside the script. Optionally you can set this as a system environment variable as well.

From the command line use the mayapy application to run the runtests.py script:

/path/to/mayapy.exe runtests.py

You may need to import the maya.standalone depending on what your tests do.

import maya.standalone
maya.standalone.initialize(name='python')
