The document discusses using setup.py and setup.cfg files to define test and documentation requirements and install them. It shows how to define test requirements in setup.py and install them with pip. It also shows how to define an "alias" in setup.cfg to install additional requirements for development and documentation tasks.

1. setup.py/setup.cfg

2. setup.py
tests_require = ["nose", "coverage", "webtest"]
setup(
tests_require=tests_require,
extras_require={
"testing": tests_require,
"docs": ["sphinx"],
},
)

3. これまでのおまいら
pip install -e .
cat > requirements.txt
nose
coverage
sphinx
^D
pip install -r requirements.txt

4. setup.cfg
[aliases]
dev = develop easy_install hoge[testing] hoge
[docs]

5. これからのおまいら
python setup.py dev

6. まとめ
extras_requireは便利だね！
