Challenges

How the scheduled automated tests are executed?

Which user data is user for the login in the vCloud?

Problem: The users use different login data in the ALM and virtualization environment

How can we store the user information so that we enable a cost calculation related to the use in projects?

Limiting the vCloud vApp selection possibilities in ALM (so that only the vApps that are

relevant for a certain project are selectable)

The IP address of the vApp in the vCloud is only known at runtime.

It can’t be entered by the use when he’s planing the test task.

The version number of the build (TFS-Nightly Build) is not known the previous day.

This means the system needs to search for the latest installed productversion

Seite 31

Technical Implementation - API functions/accesses

All the methods that are addressed through the vCloud API are implemented in a COM

component

This COM component needs to be installed on each local client which wants to use the

functionallity

It’s possible to install the component interactive or over netinstall

If the component is missing, the system will encounter the following error message:

Topic: Select the SWD-Virtualisierungsumgebung

Fill in the fields and send the ticket

The workflow is analogue to other IT tickets

Seite 36

Technical Implementation - UI Adaptations

In the ALM module Test-Plan, we added information fields for describing the test

environment of the test-cases

In the ALM module Test-Lab, we have added the dialog to select the vApp from the

vCloud

In the test-lab we added the Buttons for „Select vApp Template“, „Start vApp“ and

„Manage Tasks“

We built a wizard in ALM to schedule the automated tests

We added Tabs for “vCloud Automation”, “TLC Filter criteria” and “vCloud

Automation log”

Seite 37

Technical Implementation – Schedule Server

Tasks for the time-controlled administration/start of automatic scripts are created

by using a wizard.

The task administration runs on a separate (scheduler) machine in a unique

database

The scheduler machine then carries out the tests from ALM and starts the

corresponding machine in vCloud

Seite 38

Technical Implementation – ALM-DB expanded

The implementation is done by using the current REST API of the VMWare vCloud

Directory Version 5.1

The accesses on the vCloud are documented in the memo field „vApp Automation

Log“, which is part of each test set in ALM

The ID of the created vApp is stored in the „vApp-ID“ field of the ALM test set.

This makes it usable through the following functionalities, such as the VAPI-XP-Test

for stopping the vApp.

Seite 39

Technical Implementation - Basic Functionality

HP ALM - vCloud connection assures the following operations

User login and logout

Access to organisation structures and catalogues (read-only)

Find an image in the catalogue by searching for its name

Deploy and start an vApp from the catalogue

Shutdown the vApp

Delete an vApp to release the resources

New templates for virtual machines are requested in the existing workflow through the

IT-Ticketsystem

Seite 40

Open Tasks

ALM needs to be connected to LDAP

Otherwise, another solution needs to be found for transmitting the vCloud account,

so that the process can be executed automated in the background.

How can we store the user information so that we enable a cost calculation related

to the use in projects?

Changes in the QC Hardware Structure

Previous workplace of a QC employee

1x desktop as workstation machine

1-n Desktops as test machines

Current workplace of a QC

employee

1x Laptop with 2 monitors

-> minus 24%*

* additinally savings for software/OS, electricity consumption, office space etc.

vCloud-HP-ALM Connector

VMware vCloud-HP-ALM Connector

"We’re using the vCloud as a self-service

portal for testing environments.

After the nightly build process, the Lexware

products are installed AUTOMATICALLY on

virtual machines in the vCloud.

The test cases for automated testing are

stored in HP-ALM.

By combining the two systems, it is possible

to program automated tests in the vCloud

and store the results in the HP-ALM
