1, 什么是Tempest
tempest ├── api # API的测试集 ├── cli # OpenStack的命令行工具测试集 ├── common # 一些公共的工具类和函数 ├── scenario # 对OpenStack的常用场景进行测试，包括基本的启动VM，挂载volumn和网络配置等 ├── services # tempest自己实现的OpenStack API Client，自己实现是为了不让一些bug隐藏在官方实现的Client里面。 ├── stress # 压力测试集，利用multiprocessing来启动多个进程来同时对OpenStack发起请求。 ├── thirdparty # EC2兼容的API测试集 ├── whitebox # 白盒测试集，主要是对DB操作，然后发起请求，然后比对结果 2、tempest是通过nose驱动的，python语言编写，使用testtools和testresources等几个测试工具库 3、tempest.test.BaseTestCase,BaseTestCase声明config属性,读取配置文件 4、tempest.test.TestCase声明很多工具函数，供调用 5、每个测试可以分别测试JSON格式和XML格式
安装与使用参考文档 http://docs.OpenStack.org/developer/tempest/overview.html
下载tempest
# git clone https://github.com/openstack/tempest.git # cd tempest # python setup.py install # pip install -r requirements.txt
生成配置文件
# pip install tox
# sudo apt-get install curl # tox -egenconfig # cp etc/{tempest.conf.sample,tempest.conf}
编辑tempest.conf 文件
参考文档 http://docs.openstack.org/developer/tempest/configuration.html#tempest-configuration

2, 安装 tempest
$ git clone https://github.com/openstack/tempest/ # 下载源码$ pip install tempest # 安装tempest项目
如果pip install 报错，比如某个Python包版本冲突或者之类的，可以先执行下$ pip install -r tempest/requirements.txt # 安装Python依赖包
然后再执行$ pip install tempest
还需要安装一下模块。
pip install nose
pip install oslo.log
pip install testrepository
pip install paramiko
安装urllib3
wget https://pypi.python.org/packages/3b/f0/e763169124e3f5db0926bc3dbfcd580a105f9ca44cf5d8e6c7a803c9f6b5/urllib3-1.16.tar.gz#md5=fcaab1c5385c57deeb7053d3d7d81d59 tar xvf urllib3-1.16.tar.gz && cd urllib3-1.16/ python setup.py install
3， 初始化 Tempest

4，Tempest Coding Guide
https://docs.openstack.org/developer/tempest/HACKING.html
5， 执行部分测试用例
testr run tempest.api.compute.admin.test_delete_server.py
6，运行测试
执行所有测试
nosetests tempest
执行某一个包下的测试
nosetests tempest/tests/identity
执行一个测试代码
nosetests tempest/api/identity/v3/test_projects.py
