大多數情況下修改OpenSTack community 的各個project source code 需要提交對應的unit test, 但是由於dependency的環境版本變化，unit test會失敗，本文簡單介紹如何運行/project/run_tests.sh.
以OpenStack/Neutron 爲例 ：
使用虛擬環境安裝包
# /opt/stack/neutron/requirements.txt 是neutron project下依賴的安裝包
tools/with_venv.sh pip install -r /opt/stack/neutron/requirements.txt # /opt/stack/neutron/test_requirements.txt 是neutron project下依賴的測試安裝包
tools/with_venv.sh pip install -r /opt/stack/neutron/test_requirements.txt不使用虛擬環境
pip install --upgrade -r requirements.txt
pip install --upgrade -r test-requirements.txt升級
tools/with_venv.sh pip install --upgrade /opt/stack/neutron/requirements.txt tools/with_venv.sh pip install --upgrade /opt/stack/neutron/test_requirements.txt顯示結果 ：
Successfully installed amqplib jsonrpclib python-neutronclient alembic six Mako
