• CSIT suites that test components from multiple project repositories at the same time 
  • such CSIT tests may have to be separated using additional simulators, or
  • project repository structures themselves may have to be reconsidered, or
  • the possibility of combining branches from multiple repositories under the same commit needs to be provided (if gerrit allows?)
  • In any case, the division between the images under test and images that are just necessary dependencies should be clearly made and documented
    • the images under test should be coming from the commit branch
    • in the case of necessary dependencies it must be decided whether they should be provided as simulators or real components
      • if provided as real components, they should be referred to with a fixed, unchanging released version number and should be stable and mature enough to develop on
        • ONAP's (unintentional?) practice of allowing the same versioned image to be changed might prove is problematic
    • project-specific simulators that are built on the fly are trivial case from dependency handling point of view, but if common simulators are in use, dependency considerations for them are the same as with real components
• Jenkins templates have to be redesigned to support unified approach for triggering review branch-specific artifact and docker builds, CSIT execution and voting chain as part of review verification
  • The redesign should also allow testing locally built docker images in local environment with CSIT as effortlessly as possible
• CSITs will become blockers for merging code
  • local pre-commit verification should be supported better by common CSIT tools

  • are all projects and suites mature enough to deal with that?

• Docker image production practices will have to should be unified (see Docker Image Build Guidelines, Independent Versioning and Release Process and Release Versioning Strategy)

...

• New templates have been introduced for all verification steps (see Project-specific CSIT structure ) while all the existing ones have been left untouched
  • review-verification template
    • triggered by review commit
    • has verify vote on the review
    • triggers artifact builds
      • Should maybe include also Sonar analysis in the future - those are currently still completely separate jobs executed only on merged code
      should trigger artifact build (Sonar analysis, code coverage etc.)
      • this is not introduced yet in the verification template,
      • there are also no suitable templates for the artifact builds themselves (separate templates per "artifact-type" will probably be needed)
    • triggers docker image build - different types of docker builds each require their own templates (identified and separated by "artifact-type"), and so far we have them for
      • maven docker build
      • golang docker build
      • images are not pushed to Nexus3
    • triggers CSIT execution that tests the produced docker images
    • common project-csit template for all CSIT jobs
  • merge-verification template
    • triggered by merge
    • should trigger triggers artifact build in the same way as review-verification
    • triggers docker image build in the same way as review-verification but builds the images from master
    • triggers CSIT execution that tests the produced docker images in the same way as review-verification
    • triggers job for tagging the docker images verified by CSIT with STAGING
      • should push them to ONAP staging Nexus3 (this is implemented per project, and all the existing ones are still pushing to ONAP snapshot Nexus3)
  • Specifying exact docker image versions to be tested by CSIT has been solved by using a new unique docker tag
    • this is provided by UNIQUE_DOCKER_TAG Jenkins environment parameter, which is, in practice, BUILD_ID of the triggering verification job
  Common CSIT scripts (run-csit.sh etc) in CSIT repo and related procedures (setup, tests, teardown and related result collection) are still maintained
  • the decision to use any of these is left to projects
    • the existing examples so far (music and ccsdk/distribution) clone integration/csit and use the common scripts and corresponding directory structure
    • any new project that uses the same approach should ensure that the cloned integration/csit branch corresponds the branch of the project whenever possible  No images are pushed to Nexus3 as a result of merge-verification either; publication of new images still remains the responsibility of separate docker staging etc. jobs 
• Execution of CSIT tests and incorporating locally built test images should be made as easy as possible following common guidelines
  • Local docker build instructions should be maintained and easily accessible (for example, as part of CSIT README.md in the project repository)
  • Test environment setup should be as automated as possible (project-specific dependencies should be handled by the setup scripts)
  • Need for specific environment variables (like , for example, GERRIT_BRANCH) should be minimized and preferably avoided altogether  
  What is the significance of Java/Python/etc. SNAPSHOT/STAGING/RELEASE artifacts in Nexus? Do they have any actual role, or are the docker builds always creating those artifacts for themselves on the fly (against current Docker Image Build Guidelines)?
  • Maven repositories are in old ONAP Nexus 
• Artifact builds should take care of code coverage/Sonar analysis
  • apparently currently there are no common templates dealing with Sonar? (instead, all the project have their custom Sonar JJB definition)
  • all the Sonars run on daily schedule instead of being triggered
  • are projects mature enough to define the various Sonar violations as review blockers?
    • can we give each project the power to define their own quality gates?
