Metadata

  • Branch: chore/ci-optimize-coverage-generation
  • Commit Message: perf(ci): optimize coverage report generation
  • Milestone: v3.8.0
  • Parent Epic: #1678

Summary

The coverage_report nox session currently runs all Behave tests sequentially under slipcover to generate the coverage report. This is a potential performance bottleneck, as running the entire test suite in a single process can be time-consuming.

Subtasks

  • Investigate methods to parallelize the collection of coverage data. This might involve running tests in parallel and then merging the coverage reports.
  • Evaluate alternative coverage tools that might offer better performance than slipcover for this project's needs.
  • Implement the chosen optimization to reduce the execution time of the coverage_report session.
  • Verify that the new implementation generates accurate coverage reports and that the overall project coverage remains >= 97%.
  • Run nox (all default sessions), fix any errors.

Definition of Done

  • The execution time of the coverage_report nox session is significantly reduced.
  • The generated coverage reports are accurate.
  • 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.

Closing as duplicate of #2299.

This issue ("Optimize coverage report generation") covers the same scope as #2299 ("Optimize coverage report generation to avoid a separate sequential test run"), which is more specific about the root cause (duplicate test execution). Consolidating to avoid duplicate work.
