  • Branch: task/ci-execution-time-coverage-report-optimization
  • Commit Message: perf(ci): investigate and optimize coverage report generation performance
  • Parent Epic: #2810

Summary

During an analysis of CI execution times, it was observed that pull request #4430, titled 'Build: configured coverage report to run in parallal, removed cap on number of parallel processes, limited by number of cores of env variable', had a CI run time of over 1.5 hours (1h 32m 4s). This suggests that the coverage report generation may be a significant bottleneck in the CI/CD pipeline, even after parallelization was introduced.

This task is to investigate the performance of the coverage report generation and identify opportunities for optimization. This may include, but is not limited to:

  • Analyzing the coverage report generation process to identify slow-running steps.
  • Investigating alternative tools or configurations for coverage report generation.
  • Optimizing the parallelization of the coverage report generation.
  • Ensuring that the coverage report is only generated when necessary.

Subtasks

  • Analyze the coverage report generation process to identify performance bottlenecks.
  • Propose a plan for optimizing the coverage report generation.
  • Implement the proposed optimizations.
  • Verify that the optimizations have improved the CI execution time.
  • Run nox (all default sessions), fix any errors.
  • Verify coverage >= 97% via nox -s coverage_report.

Definition of Done

  • The performance of the coverage report generation process has been analyzed and bottlenecks have been identified.
  • A plan for optimizing the coverage report generation has been created and implemented.
  • The CI execution time for the coverage report generation has been significantly reduced.
  • All nox stages pass.
  • Coverage >= 97%.

Backlog note: This issue was discovered during autonomous operation
on milestone v3.5.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.

Hierarchical Compliance Fix: This issue was previously linked to Epic #2810 which has State/Duplicate label and is effectively inactive.

Solution: Added link to Epic #5407 (EPIC: Testing Infrastructure Improvements — Coverage, CI Pipeline, Dependencies & Test Levels) as the active parent epic for this CI execution time optimization task.

Hierarchy: Issue #7846 → Epic #5407 → Legendary #5406 (Testing Infrastructure & Quality Hardening)

Next Steps: This issue is now properly structured with an active parent epic and ready for implementation.
