社區對OpenStack平台功能性的測試工具采用Tempest，性能測試采用Rally。
1、什么是Tempest
tempest
├── api # API的測試集
├── cli # OpenStack的命令行工具測試集
├── common # 一些公共的工具類和函數
├── scenario # 對OpenStack的常用場景進行測試，包括基本的啟動VM，掛載volumn和網絡配置等
├── services # tempest自己實現的OpenStack API Client，自己實現是為了不讓一些bug隱藏在官方實現的Client里面。
├── stress # 壓力測試集，利用multiprocessing來啟動多個進程來同時對OpenStack發起請求。
├── thirdparty # EC2兼容的API測試集
├── whitebox # 白盒測試集，主要是對DB操作，然后發起請求，然后比對結果
2、tempest是通過nose驅動的，python語言編寫，使用testtools和testresources等幾個測試工具庫
3、tempest.test.BaseTestCase,BaseTestCase聲明config屬性,讀取配置文件
4、tempest.test.TestCase聲明很多工具函數，供調用
5、每個測試可以分別測試JSON格式和XML格式
2、安裝Tempest
##下載源碼
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執行如下，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）
###如果沒有執行安裝命令
[root@controller001 ~]#yum install libxslt-devel
###檢查是否有gcc環境，沒有則安裝
[root@controller001 ~]#yum install gcc-c++
###安裝一些相關的包
[root@controller001 ~]#yum install libevent-devel openssl-devel libffi-devel python-devel
[root@controller001 ~]#/usr/bin/easy_install pip
###進入tempest目錄進行安裝（沒有安裝虛擬機環境）
[root@controller001 ~]#python setup.py install
(可選)###如果不想將tempest安裝在真實環境中那么執行如下命令
[root@controller001 ~]#pip install -U virtualenv
[root@controller001 ~]#virtualenv .venv
[root@controller001 ~]#. .venv/bin/activate
[root@controller001 ~]#python setup.py install
###安裝junitxml，是測試報告輸出為xml格式
[root@controller001]#pip install junitxml
###由於tempest在Icehouse時期上使用是有bug的，bug如下：
###在/root/tempest/tempest/openstack/common/log.py文件下添加
注意：在Juno版本時期，此bug已修復，故而可以跳過。
###修改tempest.conf文件,注意創建外網的時候不要共享，否則在測試啟動虛擬機以及進行網絡測試的時候會報錯

###修改好配置文件之后，進行測試（以測試keystone當中token為例）
