Attest releases are tested and verified to work on CPython 2.5 up to 3.2 and on PyPy 1.5 (depending on the release, see the changelog). Older versions of Python do not support all the modern features used with Attest.
Install as usual from PyPI with either pip or easy_install:
$ pip install Attest $ easy_install Attest
This will also pull the two dependencies (progressbar and pygments) used for producing fancy test reports on the command line. These are actually optional, and if you prefer you can install Attest without them:
$ pip install --no-deps Attest $ easy_install -N Attest
You can also write your setup script to run tests and it will also handle test-specific dependencies such as Attest for you:
from setuptools import setup setup( tests_require=['Attest'], test_loader='attest:auto_reporter.test_loader', test_suite='path.to.tests', )
This will install Attest if needed when you run tests but not when people install your package.
$ python setup.py test
Another option is to run tests with Tox which lets you test in clean virtual environments against multiple Python runtimes and dependency sets.
A typical tox.ini might look something like this:
[tox] envlist = py25, py26, py27, py31, py32, pypy [testenv] deps = Attest commands = python -mattest.run path.to.tests
Now Tox will run your tests against all the listed Python runtimes, provided you have them installed on your machine.
