python程序的标准化测试工具-tox

Welcome to the tox automation project

vision: standardize testing in Python

tox aims to automate and standardize testing in Python. It is part of a larger vision of easing the packaging, testing and release process of Python software.

What is Tox?

Tox is a generic virtualenv management and test command line tool you can use for:
  • checking your package installs correctly with different Python versions and interpreters
  • running your tests in each of the environments, configuring your test tool of choice
  • acting as a frontend to Continuous Integration servers, greatly reducing boilerplate and merging CI and shell-based testing.

Basic example

First, install tox with pip install tox or easy_install tox. Then put basic information about your project and the test environments you want your project to run in into a tox.ini file residing right next to your setup.py file:
# content of: tox.ini , put in same dir as setup.py
[tox]
envlist = py26,py27
[testenv]
deps=pytest       # install pytest in the venvs
commands=py.test  # or 'nosetests' or ...
You can also try generating a tox.ini file automatically, by running tox-quickstart and then answering a few simple questions.
To sdist-package, install and test your project against Python2.6 and Python2.7, just type:
tox
and watch things happening (you must have python2.6 and python2.7 installed in your environment otherwise you will see errors). When you run tox a second time you’ll note that it runs much faster because it keeps track of virtualenv details and will not recreate or re-install dependencies. You also might want to checkout tox configuration and usage examples to get some more ideas.

Current features

  • automation of tedious Python related test activities
  • test your Python package against many interpreter and dependency configs
    • automatic customizable (re)creation of virtualenv test environments
    • installs your setup.py based project into each virtual environment
    • test-tool agnostic: runs py.test, nose or unittests in a uniform manner
  • supports using different / multiple PyPI index servers
  • uses pip and setuptools by default. Experimental support for configuring the installer command through install_command=ARGV.
  • cross-Python compatible: Python-2.5 up to Python-3.3, Jython and pypy support. Python-2.5 is supported through a vendored virtualenv-1.9.1 script.
  • cross-platform: Windows and Unix style environments
  • integrates with continuous integration servers like Jenkins (formerly known as Hudson) and helps you to avoid boilerplatish and platform-specific build-step hacks.
  • full interoperability with devpi: is integrated with and is used for testing in the devpi system, a versatile pypi index server and release managing tool.
  • driven by a simple ini-style config file
  • documented examples and configuration
  • concise reporting about tool invocations and configuration errors
  • professionally supported
