Metadata

  • Branch: test/ci-integration-test-execution-time
  • Commit Message: perf(ci): reduce integration test suite execution time
  • Milestone: v3.7.0
  • Parent Epic: N/A — see orphan note below

Description

The integration_tests suite is taking a long time to run, significantly slowing down the CI/CD pipeline. On average, this suite takes over 20 minutes to complete.

Analysis

  • Average Execution Time: 21 minutes (1260 seconds)
  • Impact: This is the longest running check in the CI pipeline, and it is a major bottleneck for pull request validation.

Recommendations

  • Parallelize test execution: The integration tests should be parallelized to run on multiple runners simultaneously. This could significantly reduce the overall execution time.
  • Optimize test setup and teardown: Analyze the test setup and teardown procedures to identify any unnecessary or time-consuming operations.
  • Identify and optimize slow tests: Profile the integration tests to identify individual tests that are taking a long time to run and optimize them.
  • Split the test suite: If parallelization is not enough, consider splitting the integration test suite into smaller, more manageable chunks that can be run independently.

Subtasks

  • Investigate the feasibility of parallelizing the integration tests.
  • Profile the integration tests to identify slow tests.
  • Create a plan for optimizing the test setup and teardown.
  • Implement the chosen optimization strategy.
  • Run nox (all default sessions), fix any errors.
  • Verify coverage >= 97% via nox -s coverage_report.

Definition of Done

  • The execution time of the integration_tests suite is reduced by at least 50%.
  • The CI/CD pipeline is significantly faster.
  • 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%.

⚠️ Orphan Issue — Manual Linking Required

This issue was created without a parent Epic because no open Type/Epic issues were found in the repository at the time of creation.

Per CONTRIBUTING.md, all non-Epic/non-Legendary issues must be linked to a parent Epic using Forgejo's dependency system (child blocks parent). A maintainer should:

  1. Identify or create the appropriate parent Epic for CI/test infrastructure work.
  2. Open this issue and add the parent Epic under "blocks" (so this issue blocks the Epic).

This issue will remain an orphan until that link is established.
