Metadata

  • Branch: chore/ci-execution-time-optimize-coverage-job
  • Commit Message: chore(ci): investigate and optimize coverage job execution time
  • Milestone: v3.8.0
  • Parent Epic: #1678

Summary

The coverage CI job is consistently one of the longest-running jobs in the CI pipeline. On average, it takes over 10 minutes to complete. This significantly slows down the feedback loop for developers and increases the overall CI execution time.

Subtasks

  • Analyze the coverage job to identify the bottlenecks.
  • Investigate opportunities for optimization, such as:
    • Caching dependencies.
    • Parallelizing tasks.
    • Optimizing the coverage report generation.
  • Implement the identified optimizations.
  • Run nox (all default sessions), fix any errors.
  • Verify coverage >=97% via nox -s coverage_report.

Definition of Done

  • The execution time of the coverage job is reduced by at least 50%.
  • The changes are deployed to the CI pipeline.
  • All nox stages pass.
  • Coverage >= 97%.
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
  • The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
