Metadata

  • Branch: test-infra/ci-execution-time/slow-unit-tests
  • Commit Message: perf(ci): parallelize and optimize unit_tests suite execution time
  • Milestone: v3.8.0
  • Parent Epic: #1678

Description

The unit_tests suite is taking a long time to run. While not as slow as the integration or e2e tests, there is still room for improvement.

Analysis

  • Average Execution Time: 1 minute (60 seconds)
  • Impact: While not a major bottleneck, optimizing the unit tests will contribute to a faster CI/CD pipeline.

Recommendations

  • Parallelize test execution: The unit tests should be parallelized to run on multiple runners simultaneously.
  • Identify and optimize slow tests: Profile the unit tests to identify individual tests that are taking a long time to run and optimize them.

Subtasks

  • Investigate the feasibility of parallelizing the unit tests.
  • Profile the unit tests to identify slow tests.
  • Implement the chosen optimization strategy.
  • Update documentation to reflect any changes to the test execution process.
  • Verify coverage >= 97% via nox -s coverage_report
  • Run nox (all default sessions), fix any errors

Definition of Done

  • The execution time of the unit_tests suite is reduced by at least 30%.
  • The CI/CD pipeline is faster as a result of this change.
  • The changes are documented and communicated to the team.
  • 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, 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.
  • All nox stages pass
  • Coverage >= 97%
