  • Branch: chore/ci-profile-slow-unit-integration-tests
  • Commit Message: chore(ci): profile and optimize slow unit and integration tests
  • Milestone: v3.8.0
  • Parent Epic: #1678

Background and Context

The unit_tests and integration_tests jobs are essential for maintaining code quality, but they can become a bottleneck in the CI pipeline as the codebase grows. To proactively manage this, we should profile the tests to identify and optimize the slowest ones.

Expected Behavior

The unit and integration test suites are profiled, the slowest tests are identified, and targeted optimization issues are created to address them — keeping CI execution time within acceptable bounds as the codebase scales.

Acceptance Criteria

  • Unit test suite has been profiled and the top 5–10 slowest Behave scenarios are identified.
  • Integration test suite has been profiled and the top 5–10 slowest Robot Framework test cases are identified.
  • For each identified slow test, a new issue is created with: the test name, current execution time, and a proposed optimization strategy.

Subtasks

  • Profile Unit Tests: Use a Python profiler (e.g., cProfile, py-spy) to measure the execution time of each Behave scenario in the unit_tests suite.
  • Identify slowest unit test scenarios: Compile a ranked list of the top 5–10 slowest unit test scenarios.
  • Analyze slow unit tests: Examine code and test setup for the identified scenarios to find optimization opportunities.
  • Profile Integration Tests: Use Robot Framework's built-in profiling capabilities or an external profiler to measure the execution time of each test case in the integration_tests suite.
  • Identify slowest integration test cases: Compile a ranked list of the top 5–10 slowest integration test cases.
  • Analyze slow integration tests: Examine test implementation (setup, teardown, component interactions) for optimization opportunities.
  • Create Optimization Issues: For each identified slow test, create a new issue with detailed information about the test, its current execution time, and a proposed optimization strategy.
  • Run nox (all default sessions), fix any errors.
  • Verify coverage >= 97% via nox -s coverage_report.

Definition of Done

  • The unit and integration test suites have been profiled.
  • A ranked list of the slowest tests has been compiled and documented.
  • Issues have been created for optimizing each identified slow test.
  • 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.
  • 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.
  • All nox stages pass.
  • Coverage >= 97%.
