tox 試用

安裝

pip install tox

tox 使用

tox 包含一個tox.ini 文件，此文件能夠自動，或者手工編寫

• tox.ini 文件格式

# content of: tox.ini , put in same dir as setup.py

[tox]

envlist = py27,py36

​

[testenv]

# install pytest in the virtualenv where commands will be executed

deps = pytest

commands =

    # NOTE: you can run any command line tool here - not just tests

    pytest

• 自動生成的方法

  使用 tox-quickstart

參考以下：

Welcome to the tox 3.12.1 quickstart utility.

This utility will ask you a few questions and then generate a simple configuration file to help get you started using tox.

Please enter values for the following settings (just press Enter to accept a default value, if one is given in brackets).

​

What Python versions do you want to test against?

            [1] py36

            [2] py27, py36

            [3] (All versions) py27, py34, py35, py36, pypy, jython

            [4] Choose each one-by-one

> Enter the number of your choice [3]: 

What command should be used to test your project? Examples: - pytest

"

            - python -m unittest discover

            - python setup.py test

            - trial package.module

> Type the command to run your tests [pytest]: 

What extra dependencies do your tests have?

default dependencies are: ['pytest']

> Comma-separated list of dependencies: hashids

Finished: ./tox.ini has been created. For information on this file, see https://tox.readthedocs.io/en/latest/config.html

Execute `tox` to test your project.

效果

# tox (https://tox.readthedocs.io/) is a tool for running tests

# in multiple virtualenvs. This configuration file will run the

# test suite on all supported python versions. To use it, "pip install tox"

# and then run "tox" from this directory.

[tox]

envlist = py27, py34, py35, py37

[testenv]

    hashids

    pytest

commands =

    pytest

項目配置

• 項目結構

  由於系統只安裝了python2.7 以及3.7 因此tox.ini 稍有修改

├── README.md

├── myids

│ └── __init__.py

├── setup.py

└── tox.ini

• 項目說明
  myids/init.py

 

from hashids import Hashids

hashids = Hashids()

def generateID():

    hashid = hashids.encode(123, 456, 789)

    print(hashid)

if __name__ == '__main__':

    generateID()

setup.py

import setuptools

​

with open("README.md", "r") as fh:

    long_description = fh.read()

​

setuptools.setup(

    name="myids",

    version="0.0.3",

    author="dalongrong",

    author_email="1141591465@qq.com",

    description="myids package",

    long_description=long_description,

  由於我沒有添加測試，因此會有一些關於測試的錯誤提示

說明

tox 工具仍是很方便的，能夠簡化咱們測試以及構建
