eutester version 0.0.4
Guidelines for Contributing Testcases
eutester is an attempt to leverage existing test code to make test writing faster and standardized.
Installation
If easy_install is not available in your environment use your package manager to install python-setuptools
yum install python-setuptools gcc python-devel
apt-get install python-setuptools gcc python-dev
Installing eutester and its dependencies is as easy as:
easy_install eutester
For development purposes you can then clone the code from github and then reinstall with your changes
git clone https://github.com/eucalyptus/eutester.git
cd eutester
[CHANGE CODE]
python setup.py install
Main Classes
eutester contains the framework pieces like parsing config/creds, setting up connections and providing test primatives
eucaops uses the framework provided by eutester to provide validated higher order operations on those cloud connections
Example test cases written with this library can be found in the testcases/unstable directory of the source tree
Design
Eutester is designed to allow a user to quickly generate automated tests for testing a Eucalyptus or Amazon cloud. In the case of testing a private cloud a configuration file can be used to create cases that require root access to the machines. The config file describes a few things about the clouds configuration including the bare metal machine configuration and IPs.
The eucaops
class can be imported in order to use pre-defined routines which validate common operations on the cloud:
from eucaops import Eucaops
Constructor
The basic constructor can be used for 2 different connections:
-
Private cloud with root access - CLC SSH, Cloud, and Walrus connections
Purpose - connect to and manipulate Eucalyptus components using boto and command line. Recommended to use Eucaops.
Required arguments: root password, config file with topology information
Optional arguments: credential path so that new credentials are not createdprivate_cloud = Eucaops( password="my_root_pass", config_file="cloud.conf") private_cloud.sys("euca-describe-availability-zones") ### use local credentials to determine viable availability-zones
-
Public cloud - local SSH, EC2 and S3 connections
Purpose - can be used to wrap euca2ools commands installed locally on the tester machine or with Eucaops
Required arguments: credential pathpublic_cloud = Eucaops(credpath="~/.eucarc") public_cloud.run_instance(image) ## run an m1.small instance using image
