Metadata

  • Branch: feature/ci-conditional-test-execution
  • Commit Message: feat(ci): implement conditional test execution to reduce pipeline run time
  • Milestone: N/A — Backlog (see note below)
  • Parent Epic: #1678

Background and Context

The current CI pipeline runs the entire test suite on every push and pull request, regardless of the changes made. This is inefficient, especially for small changes that only affect a small part of the codebase. Implementing conditional test execution would allow the CI pipeline to only run the tests that are relevant to the changes in a pull request, significantly reducing CI execution time and providing faster feedback to developers.

This issue is closely related to the broader CI Execution Time Optimization effort tracked in Epic #1678.

Expected Behavior

The CI pipeline should detect which parts of the codebase have changed and only execute the tests that are relevant to those changes, while still guaranteeing full coverage on merges to master.

Subtasks

  • Research and choose a strategy for conditional test execution. Options include:
    • Using pytest-xdist with the --changed-first flag
    • Analyzing the dependency graph of the code to determine which tests are affected by the changes
    • Using a dedicated tool for test selection, such as bazel or pants
  • Implement the chosen strategy in .forgejo/workflows/ci.yml
  • Ensure that the conditional test execution is reliable and does not miss any required tests
  • Update features/ci_workflow_validation.feature to assert conditional execution steps are present
  • Update the documentation to explain how the conditional test execution works
  • Verify all nox stages pass after changes
  • Confirm coverage ≥ 97%

Definition of Done

  • The CI pipeline only runs the tests that are relevant to the changes in a pull request
  • The CI execution time is significantly reduced for small changes
  • The conditional test execution is reliable and does not compromise the quality of the tests
  • features/ci_workflow_validation.feature is updated to cover the new conditional execution logic
  • All nox stages pass
  • Coverage >= 97%

Backlog note: This issue was discovered during autonomous operation
on milestone v3.8.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.
