Metadata

Branch: task/v3.8.0-ci-conditional-test-execution
Commit Message: feat(ci): implement conditional test execution based on changed files
Milestone: v3.8.0
Parent Epic: #1678

Background and Context

The CI pipeline currently runs all tests on every commit. This is safe but can be inefficient. For many changes, only a subset of tests are relevant. Implementing a system to run only the tests affected by a change can significantly speed up the CI pipeline.

⚠️ Potential Duplicates Detected: This issue may overlap with existing open issues:

#1793 — TEST-INFRA: [ci-pipeline-design] Implement conditional test execution based on code changes

#1758 — CI Pipeline: Implement conditional test execution

A maintainer should review and consolidate if appropriate before work begins.

Expected Behavior

The CI pipeline should detect which files were changed in a commit, map those changes to the affected tests, and execute only the relevant subset — reducing CI wall-clock time and runner resource usage.

Acceptance Criteria

The CI pipeline identifies changed files in a commit.
Changed files are mapped to their corresponding affected tests.
Only the affected tests are executed by the CI pipeline.
The CI pipeline is measurably faster due to conditional test execution.

Subtasks

Implement a system to identify the changes in a commit (e.g., via git diff)
Implement a system to map changes to affected tests (change-to-test mapping logic)
Configure the CI workflow to run only the affected tests based on the mapping
Tests (Behave): Add BDD scenarios covering the change-detection and mapping logic
Tests (Robot): Add integration test verifying the CI conditional execution end-to-end
Verify coverage >= 97% via nox -s coverage_report
Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly (feat(ci): implement conditional test execution based on changed files), 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 (task/v3.8.0-ci-conditional-test-execution).
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
The CI pipeline runs only the tests affected by a change.
The CI pipeline is faster due to conditional test execution.
All nox stages pass.
Coverage >= 97%.
