ONAP releases are organized through review milestones that take place separately for every projects.

Release Kick-Off

ReviewsReviewMilestonesMilestoneDescriptionActivities
Kick-OffM0
  • The goal of the Kick-Off review is to declare intention to participate in an ONAP Release.
  • The proposed Project aligns with the architecture, team is in place, draft project plan is well-formed in wiki. 
  • Once approved, the planning process opens.

To reach Release Kick-Off review, the team must:

Once the Release Kick-Off passed, the following activities are performed:

  • Release Use Case are iteratively worked on, submitted to TSC and proposed to GB.
  • Development of feature code.

Milestones
MilestoneDescriptionActivities
Functionality FreezeM2
  • The goal of the Functionality Freeze is to mark the end of
the API definition development activities. At Functionality Freeze, API stubs must be in implemented
  • adding functionality in the Release.
  • After Functionality Freeze, no new visible functionality is to be added to the current ONAP release.
  • After Functionality Freeze, all API definition changes must be submitted to TSC for review and approval.
  • All provisional APIs are at least functional (at a beta-quality level) if not yet fully tested
    • The API definition development activities is over and a stable document describing the API is documented and available to the community.
    • At Functionality Freeze, the following activities have been achieved:
      • All committed functionalities have been coded.
      • CSIT Test Case are defined (Project Team).
      • All code have automated unit test (Project Team).
      • The team is using the complete Linux Foundation environment (build, Jenkins, Gerrit, FOSS, Automated Unit Test, Nexus).
      • A defined and documented final list of externally consumable APIs is available.

    To Pass Functionality Freeze, the PTL must:

    1. Fill out in project space the Deliverables for Functionality Freeze Milestone template
    2. Inform the TSC Chair and the Release Manager prior to the milestone on the availability of the deliverable

    After Functionality Freeze is passed, the team focus on:

    • Feature Test:
      • Define Feature Test plan.
      • Define Acceptance criteria.
      • Automate and execute the Feature test.
      • Prioritize defects and address at least all critical and blocking defects.

    All defects must be entered into Jira.

    API Freeze

    ReviewsReviewMilestonesMilestoneDescriptionActivities
    APIM3
    • The goal of the API Freeze is to ensure API and Data Model are Frozen.
    • Architecture should be carefully documented and stable (API, block diagram, flow diagram,... defined)At API Freeze, API stubs must be in implemented.
    • All provisional APIs are at least functional (at a beta-quality level) if not yet fully tested.
    • All externally accessible APIs & data models may not be modified. An API exception process will allow for critical changes to APIs after API Freeze.
    • Any Changes to the API must be brought to the knowledge of the TSC for review and approval. APIs include, but are not limited to, all Java classes/interfaces declared public, all YANG models, all TOSCA profiles, all config file YANG schemas, and all REST/RESTCONF calls including the full URL with options.
    • 50% of CSIT Test case complete(Project Team).
    • Issues brought to TSC or Architecture Committee (ARC).
    Note: Projects in Incubation State would have a lower threshold than projects in Mature/Core State.
    Project in Core State would have a high threshold
    • Coordinator.

    Prior to Architecture review, Project teams must also review APIs with the Architecture Committee (ARC).


    To pass Architecture review, the PTL must:

    1. Fill out in project space the Deliverables for Architecture Milestone template
    2. Inform the TSC Chair and the Release Manager prior to the milestone on the availability of the deliverable

    It is important to understand that activities started at Functionality Freeze are still ongoing until Code Freeze milestone.

    Release Code Freeze

    ReviewsReviewMilestonesMilestoneDescriptionActivities
    Code FreezeM4
    • The goal of the Code Freeze is to mark the end of the Features coding and testing and the resolution of all impacting defects (at least all Critical and Blocking defects)
    • After Code Freeze, no new features/functionality are to be allowed into the current release. Only defects identified in the Jira system are allowed. The exceptions to this include new tests, and documentation
    • Defects found after Code Freeze are still defects and they may be created and worked on. This includes packaging defects found as well
    • At Functionality Freeze, the following activities have been achieved:
        • End 2 End Continuous Integration Use Case (CSIT) is implemented (Integration Team).
        • 50% of CSIT Test case complete (Project Team).

    To pass Code Freeze, the PTL must:

    1. Fill out in their Project Space the Deliverables for Architecture Milestone template
    2. Inform the TSC Chair and the Release Manager that the milestone has been achieved (or not)
    3. Inform the TSC Chair and the Release Manager prior to the milestone on the availability of the deliverable

    At that point the Documentation is complete: Only editing and enhancing should take place after this point.

    After Code Freeze is passed, the team focus on:

    • Integration Testing
      • Coordinate with central Integration Team to ensure end to end Integration testing is understood, complete and prepare a plan for Integration Testing review
      • Refine Integration Test plan
      • Refine Acceptance criteria
      • Start automating and executing end to end Integration testing

    • After Integration Review (RC0), new RCs will be continually built, e.g., once per day, to enable rapid testing and fixing of defects. 
    • Integration plan is defined and covers correct API calls and data models between projects, alignment with use case and test framework.
    • Integration Plan should be carefully documented.

    • Prioritizing new defects and address them. In case there are blocking defects preventing the team to execute according to the plan, the defect must be fixed and a new full build made available.
    • Reviewing and polishing documentation.
    • Prepare activities to reach Release Sign-Off.
    • There is no need to create specific materials for RC1, RCx.
