社区对OpenStack平台功能性的测试工具采用Tempest，性能测试采用Rally。
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
2、安装Tempest
##下载源码
git clone https://github.com/openstack/tempest.git
cd tempest
vim requirements.txt
##添加
discover>=0.4.0
###查看python版本
python --version
###如若是2.6执行如下，2.7不需要
wget https://pypi.python.org/packages/source/u/unittest2/unittest2-0.5.1.tar.gz
tar zxvf unittest2-0.5.1.tar.gz
cd unittest2-0.5.1
python setup.py install
###查看xslt-config命令是否存在
[root@controller001 ~]# whereis xslt-config
xslt-config: /usr/bin/xslt-config（代表存在）
###如果没有执行安装命令
[root@controller001 ~]#yum install libxslt-devel
###检查是否有gcc环境，没有则安装
[root@controller001 ~]#yum install gcc-c++
###安装一些相关的包
[root@controller001 ~]#yum install libevent-devel openssl-devel libffi-devel python-devel
[root@controller001 ~]#/usr/bin/easy_install pip
###进入tempest目录进行安装（没有安装虚拟机环境）
[root@controller001 ~]#python setup.py install
(可选)###如果不想将tempest安装在真实环境中那么执行如下命令
[root@controller001 ~]#pip install -U virtualenv
[root@controller001 ~]#virtualenv .venv
[root@controller001 ~]#. .venv/bin/activate
[root@controller001 ~]#python setup.py install
###安装junitxml，是测试报告输出为xml格式
[root@controller001]#pip install junitxml
###由于tempest在Icehouse时期上使用是有bug的，bug如下：
###在/root/tempest/tempest/openstack/common/log.py文件下添加
注意：在Juno版本时期，此bug已修复，故而可以跳过。
###修改tempest.conf文件,注意创建外网的时候不要共享，否则在测试启动虚拟机以及进行网络测试的时候会报错
