3 IBM Confidential

Demo 1

Windows Server 2012 support enhancement (30218, 34043)


4 IBM Confidential

Demo 1 – what’s changed and enhanced

Removed .NET Framework 3.5 prerequisite for Windows Server 2012

Removed .NET Framework 1.0 + prerequisite for Windows

Windows Server 2012 as supported value for OSType section data category

For example:

[OSType:Windows Server 2012]

os.versionNumber=6.2+

.NET Framework is NOT a PRS windows prerequisite anymore!


5 IBM Confidential

Demo 2

As PRS adopter, I would like PRS to support number of logical processor check (34094)


6 IBM Confidential

Demo 2 – requirement and overview

Requester

JazzSM, OMEGAMON

Request Description

PRS’ existing numCPU property checks on the number of physical processors available to the operating system.

JazzSM and OMEGAMON team have requested PRS to provide a new capability to check for number of logical processors, to support their installation prerequisite scenario.

Property Name: numLogicalCPU

Supported Value: positive integer

For example:

numLogicalCPU=2


7 IBM Confidential

Demo 2 – Windows overview

Implementation

Calculated by add up number of logical processors per physical processor, reported by win32_processor class

Requirements for Windows XP, Windows 2003 and limitation for Windows 2000

** As a known Windows limitation, WMI class win32_processor does not support attribute NumberOfLogicalProcessors.

Windows XP

—Required hotfix: http://support.microsoft.com/kb/936235

—Required SP level: SP3 + (which includes the hotfix)

Windows 2003

—Required hotfix: http://support.microsoft.com/kb/932370

Windows 2000 NOT supported

Microsoft ended Windows 2000 support at July 13, 2010

Tips – how to check for hotfixUse this command to get all hotfix installed on the system:

wmic qfe list


8 IBM Confidential

Demo 2 – Windows error message


9 IBM Confidential

Demo 2 – UNIX overview

Implementation

UNIX collector executes the following commands to get the set of Logical processors available in different flavors of UNIX.

RHEL and SUSE platforms : cat /proc/cpuinfo

AIX platform : bindprocessor -q

HP-UX platform : machinfo

SunOS platform : uname -X

12 IBM Confidential

Demo 3

As PRS tester, we want to implement test automation for remote execution to achieve 50% test regression coverage (34047)


13 IBM Confidential

Demo 3 – Benefits of Test Automation Regression Testing can be close to fully automated

• previously would run regression tests manually on every platform

• less error prone

Increased test and platform coverage

• would previously run a subset of the product cfg files and test cases on a subset of platforms

• can now run the full set of ootb product cfg files and additional test cases

Reduce the amount of time spent on regression testing by at least 50%

• with every sprint and new added function we observed the amount of time required for regression increase

• previously spending average of 3 days on manual regression testing per release, now I can kick off regression tests to run overnight and review logs the next day

• benefits apply to regression testing performed not just per release but on every sprint

We can react more quickly to changing customer deliverables and unscheduled requests


14 IBM Confidential

Demo 3 – Test automation framework based on:

Ant :

generate the test build

invoke the Java classes which run STAF commands

invoke Junit tests

copy reports and result logs to report server

STAF:

run tests on remote target machines

collect logs

Java/Junit:

run STAF commands

perform verification of actual test results


15 IBM Confidential

Demo 3 – Test project in RTC – directory structure:

Project Name: com.ibm.prc.test


16 IBM Confidential

Demo 3 – Running Test builds and tests ...

Test builds are kicked off from RTC similar to dev builds

Dedicated test build machine: aclinux6223Z

Jazz build engine running on the test build machine waiting for build requests

Build engine and Test build definitions are defined in RTC

Test project can be loaded and should be viewable by anyone who has access to the Prerequisite Scanner Team in RTC


17 IBM Confidential

Demo 3 – Running Test builds and tests ...

Running a test build is as simple as selecting:

Prerequisite Scanner Test Team Build

→ Request Build

Tests are automatically run once the test build has completed...


18 IBM Confidential

Demo 3 – Developing the framework ...

Multi-stage approach:

Stage 1: develop the basic Ant scripts and manually run tests using Ant on each of the test machines, limited to a few basic tests on Linux and Windows

Stage 2: allocate and configure the Jazz build engine and RTC build definitions, update the Ant scripts to run tests locally on the build machine, added a few additional tests

Stage 3: include STAF into the framework and provide the ability to run on several remote targets, include tests for all out-of-the-box/latest product cfg files, updates to CVT cfg files as well as new section support tests.


19 IBM Confidential

Demo 3 – STAF – a bit of background info ...Software Testing Automation Framework

“Peer-to-peer pluggable framework geared toward test automation”

“Open source automation framework designed around the idea of reusable components, called services”

Easy to install and configure

Supports many different platforms

All services are available from the command line

Supports many languages, provides flexibility:

Java, C/C++Perl, Python, Rexx, Shell scriptsAntCommand line


20 IBM Confidential

Demo 3 – STAF services

we mostly make

use of these

three services


21 IBM Confidential

Demo 3 – Common tasks performed by STAF commands1. Create a unique work directory on the remote target

2. Copy the PRS build image to the remote target machine

3. Set file permissions if required

4. Untar/Unzip the PRS build image

5. If tests will be run as non-root then change file ownership to the

non-root user

6. Run PRS scripts on the remote target

7. Collect the result files and logs

8. Delete the unique work directory on the remote target


22 IBM Confidential

Demo 3 – Submitting STAF requests through Java Submitting STAF requests via Java requires a STAF handle object. The STAF handle allows you to register with STAF, submit requests, and then unregister.

STAFHandle handle = new STAFHandle("RunCVTTest");

Once a STAF handle is acquired it's used to submit requests to STAF

STAFResult result = handle.submit2(machine, service, request);

Here is an example of a method call which submits a STAF request to a remote target to run PRS – the submitSTAFRequest method is my own internal method that invokes the STAF submit2 method:

String prsCVTCommand = "prereq_checker.bat CVT detail xmlResult";

String prsCVTSTAFRequest = "START SHELL COMMAND " + STAFUtil.wrapData(prsCVTCommand) + " USERNAME " + userid + " PASSWORD " + password + " WORKDIR " + workDir + " WAIT STDERRTOSTDOUT RETURNSTDOUT";

submitSTAFRequest(handle, machine, "PROCESS", prsCVTSTAFRequest);
