OpenStack Dashboard is a Django based application that integrates with cloud compute. It provides a visual way to interact with the cloud.It provides web-based interactions with the OpenStack Compute cloud controller through the OpenStack APIs.Horizon ships with three central dashboards, a “User Dashboard”, a “System Dashboard”, and a “Settings” dashboard. Between these three they cover the core OpenStack applications and deliver on Core Support.For more information about the Openstack-Dashboard project, please visit: http://horizon.openstack.org/
In order to test horizon, we need a working OpenStack installation. So lets pull the Silver Bullet script (DevStack) from github and run it.When it is done, it will show you something like this:
horizon is now available at http://10.10.10.18/
keystone is serving at http://10.10.10.18:5000/v2.0/
examples on using novaclient command line is in exercise.sh
the default users are: admin and demo
the password: root
This is your host ip: 10.10.10.18
For Automating the test scenarios, we have to create test data and test cases. Here are a couple of possible test cases for the Login Scenario.
To automate these test cases and others like Launching an Image, Deleting Image, Running functional UI tests in a headless (no X-server), Taking Browser screenshots with no display, we will use Selenium Webdriver, PyVirtualDisplay (uses xvfb), unittest2, xlrd , firebug and a Data Driven Framework. All the data that we need in order to execute our tests will be pulled from the spreadsheet shown below. If you want to integrate your functional UI tests (Selenium/WebDriver) with Jenkins CI system then you must run your GUI tests in a headless X-server The problem is that Jenkins CI server has no display.
Let us first automate the test case for Launching of an Image.
