  1. Prerequisite Scanner Team Sprint Demo Prerequisite Scanner Sprint 12 Demo IBM Prerequisite Scanner Team December 12, 2012

  2. Key Accomplishments • PRS 1.2.0.2 Release published to FixCentral(34095) • Windows 2012 support enhancement (30218, 34043) • As PRS adopter, I would like PRS to support number of logical processor check (34094) • As PRS tester, we want to implement test automation for remote execution to achieve 50% test regression coverage (34047) • Story: Delivery PRS driver to JazzSM in support of sprint 19, 20 and milestone 8 (33982) • PRS GO training preparation (33989) Demo Demo Demo

  3. Demo 1 Windows Server 2012 support enhancement (30218, 34043)

  4. 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. Demo 2 As PRS adopter, I would like PRS to support number of logical processor check (34094)

  6. Demo 2 – requirement and overview • Requester JazzSM, OMEGAMON • Request Description • PRS’ existingnumCPU 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. 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 hotfix Use this command to get all hotfix installed on the system: wmic qfe list

  8. Demo 2 – Windows error message

  9. 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

  10. Demo 2 – UNIX output message

  11. Demo 2 – UNIX Error message Precheck.log file

  12. Demo 3 As PRS tester, we want to implement test automation for remote execution to achieve 50% test regression coverage (34047)

  13. 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. 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. Demo 3 – Test project in RTC – directory structure: Project Name: com.ibm.prc.test

  16. 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. 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. 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. 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 scripts • Ant • Command line

  20. Demo 3 – STAF services we mostly make use of these three services

  21. Demo 3 – Common tasks performed by STAF commands • Create a unique work directory on the remote target • Copy the PRS build image to the remote target machine • Set file permissions if required • Untar/Unzip the PRS build image • If tests will be run as non-root then change file ownership to the non-root user • Run PRS scripts on the remote target • Collect the result files and logs • Delete the unique work directory on the remote target

  22. 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);
