  1. EMI Quality Assurance Tools Lorenzo Dini (CERN) SA2.4 Task Leader

  2. Outline • Task Goals • Initial situation • Build, Integration, Packaging • Build and Test Infrastructure • Software Repositories • Continuous Testing • Quality Assurance • Metrics Workflow • QA Reports EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  3. SA2.4 - EMI QA Tools • EMI QA tools not only for Quality Assurance • Single tool-chain and workflow for • Build, integration, Packaging, Testing, QA • Unified project builds in a single box • Single release tool • Single dependency management • Uniform and compliant packaging • Tests stored together with configuration • QA metrics created in builds EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  4. Initial Situation EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  5. Survey Results 1 EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  6. Survey Results 2 EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  7. Survey Results 3 EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  8. Challenges • Differentcultures, environments, requirements and priorities led to different tools difficult to merge • Uniform the build environment to provide a common software engineering workflow without affect developer efficiency • Provide a comprehensive infrastructure able to satisfy the totality of needs • Introduce testing, QA metrics generation and reporting in the same tool-chain • Support everybody on a new system EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  9. Build, Integration and Packaging • Taken the versatility of the gLite ETICS system as a general framework • Adopted the ARC dependency management with EPEL and packaging with Mock (Debian with PBuilder) • Configured minimal worker nodes as dCache with packages installed as privileged user at build start and build in user space • Kept Maven to uniformly and effectively build Java components as UNICORE EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  10. Build, Integration and Packaging • Every EMI software component is configured in a single ETICS project and organized in releases • The whole release is built from source in a single minimal clean node 4 times a day • ETICS checks-out the source code, installs the dependencies using YUM/APT and triggers the build systems (Autotools, Ant, Maven) in user space • ETICS creates missing SPEC files and produces RPMs and DEBs • ETICS triggers Mock/PBuilder in a pristine environment for the packaging EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  12. Build, Integration and Packaging EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  13. Build and Test Infrastructure • Virtual infrastructure based on CERN Microsoft HyperV and Condor • >50 VMs in >10HVs available at any time for builds and tests • VMs are automatically scratched after jobs to ensure clean environments • Some high performance nodes have been dedicated to project builds to minimize the build cycle EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  14. Build and Test Infrastructure EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  15. Software Repositories • EMI software repositories are provided for each release and release candidate • These repositories are automatically populated after builds • An EMI external repository is also provided for packages not available in the OS (SL, EPEL, Debian) • Automatic ETICS repositories are also generated with the contents of the builds EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  16. Continuous Testing “The gLite Data Management Continuous Integration and Testing Process” – 14:30 EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  17. Quality Assurance • The goal of Process Metrics is to identify improvement opportunities in the way the software is developed and tested, from a process point of view. In our context the main sources of process metrics are the Defect Tracking tools used in EMI. • Product (or Internal) Metrics measure certain characteristics of the product like complexity, changeability and testability. At the moment we rely on static code analyzers to measure these characteristics. • ”Software Metrics Defines, Reports and Analysis in EMI” – 12:00 EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  18. QA Metrics Workflow Process http://gridka-school.scc.kit.edu/img/dCache_logo.gif Product

  19. Bug Tracker exporters • The middleware distributions decided not to merge their tracking systems • Agreements on fields, states, workflow and interfaces to track the process • Exporters query each system and provide a standard XML document with the data • This documents are stored and backed up on servers provided by distributions “Software Quality Assurance in EMI” – 11:00 EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  20. QA Plug-ins • QA Plug-ins are ETICS modules that run during the build and trigger common static analysis tools for QA • SLOCCount, FindBugs, PMD, Checkstyle, PyLint, RPMLint, CPPCheck, etc... • Product QA Metrics are produced and stored permanently in the ETICS repository EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  21. QA Report Generator • Queries the XML for the process metrics and the ETICS repository for the product metrics creating aggregated metrics. • Generates charts, plots and tables with QA information and fills in QA templates with the dynamic information. • Reports can be produced daily for Product Teams and Release Manager • Produces drafts for EU QA Deliverables EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  22. QA Reports: Process Metrics EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  23. QA Reports: Product Metrics EGI User Forum - EMI Technical Forum - April 11-14 Vilnius

  24. Conclusions • A very heterogeneous starting point • Uniform software engineering tool-chain • Successfully integrated EMI 0 and EMI 1 • New integrated testing and QA process • All performed improvements benefit all teams at once. • Specific solution can make a single team happier but are globally more expensive and not maintainable.
