云计算的现状及其发展趋势的分析

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Tempesttempest├── 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

[root@controller001 ~]#git clone

###查看python版本

[root@controller001 ~]#python --version

###如若是2.6执行如下，2.7不需要

[root@controller001 ~]#wget [root@controller001 ~]#tar zxvf unittest2-0.5.1.tar.gz
[root@controller001 ~]#cd unittest2-0.5.1
[root@controller001 ~]#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  -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

[root@controller001 etc]#cp etc/tempest.conf.sample etc/tempest.conf

[root@controller001 etc]# egrep "^[^#]" tempest.conf

###修改好配置文件之后，进行测试（以测试keystone当中token为例）

[root@controller001 tempest]# nosetests tempest/api/identity/admin/test_tokens.py --with-xunit --xunit-file=/root/keystone_test_tokens.xml
