Metadata

  • Branch: fix/unit-tests-ci-environment-failure
  • Commit Message: fix(ci): resolve unit_tests CI environment failure causing persistent ~6m45s timeout
  • Milestone: v3.2.0
  • Parent Epic: #2597

What Was Tested

UAT testing of issue #2597 (CI quality gates restoration). Specifically testing whether PR #2629 (fix/master-ci-quality-gates) resolves the unit_tests CI failure on master.

Expected Behavior (from spec/issue #2597)

Per issue #2597 Acceptance Criteria:

  • All 11 CI jobs must pass on master: lint, typecheck, security, quality, unit_tests, integration_tests, e2e_tests, coverage, build, docker, helm
  • unit_tests (nox -s unit_tests) must pass in CI with all 587 Behave BDD scenarios passing

Actual Behavior

The unit_tests CI job is persistently failing after ~6m45-6m54s in the CI environment across multiple commits on both master and the fix branch:

Commit Branch unit_tests Status
6e94e1d3 master Failing after 6m45s
938ea819 fix/master-ci-quality-gates Failing after 6m54s
0851050d fix/master-ci-quality-gates Failing after 6m48s

The failure is CI-specific: the PR author reports 587 features pass locally. The consistent ~6m45s failure time suggests a timeout or specific test scenario failure that only manifests in the CI container environment.

Root Cause Analysis

The CI environment runs in a fresh python:3.13-slim Docker container. The unit_tests job:

  1. Creates a template SQLite DB via scripts/create_template_db.py
  2. Runs behave-parallel with 2 processes (default for CI) across all 587 feature files

The consistent ~6m45s failure time (not an immediate failure) indicates:

  • The template DB creation succeeds
  • Some tests run successfully
  • A specific test or group of tests fails after ~6 minutes

Possible root causes:

  1. Parallel test isolation issue: The multiprocessing.Pool with fork start method may have race conditions in CI that don't manifest locally
  2. CI-specific environment difference: The python:3.13-slim container may have different behavior for SQLite, file system, or module loading
  3. Specific failing scenario: One or more Behave scenarios fail in CI but not locally, possibly due to environment-specific behavior (e.g., missing system packages, different file permissions, or timing issues)
  4. TDD expected-fail tag issue: A @tdd_expected_fail scenario may be failing with a non-AssertionError exception in CI (which prevents inversion), causing it to report as a real failure

Steps to Reproduce

  1. Push any commit to fix/master-ci-quality-gates branch
  2. Wait for CI to run the unit_tests job
  3. Observe failure after ~6m45s

Code Location

  • noxfile.pyunit_tests session definition (line 162)
  • scripts/run_behave_parallel.py — parallel runner
  • scripts/create_template_db.py — template DB creation
  • features/environment.py — TDD tag inversion logic

Impact

This is a P0 blocker. Until unit_tests passes in CI:

  • PR #2629 cannot merge
  • Master CI remains broken
  • All other PRs are blocked from merging
  • No releases can be cut

Subtasks

  • Obtain full CI logs for the unit_tests job failure from the most recent run on fix/master-ci-quality-gates to identify the exact failing scenario(s)
  • Reproduce the failure locally using the same python:3.13-slim Docker container environment used in CI
  • Identify whether the failure is a parallel test isolation issue (race condition in multiprocessing.Pool with fork start method)
  • Identify whether any @tdd_expected_fail scenario is raising a non-AssertionError exception in CI (preventing tag inversion)
  • Identify whether any CI-specific environment difference (missing packages, file permissions, SQLite behavior) causes the failure
  • Fix the root cause in source code (src/), test infrastructure (features/environment.py, scripts/run_behave_parallel.py), or test scenarios — without suppressing any quality gate
  • Verify the fix by pushing to fix/master-ci-quality-gates and confirming unit_tests CI job passes consistently
  • Confirm all 587 Behave BDD scenarios pass in CI (not just locally)
  • Run full nox suite locally to confirm no regressions introduced by the fix
  • Verify coverage remains >= 97% after the fix

Definition of Done

  • The unit_tests CI job passes consistently (not just locally) on the fix/master-ci-quality-gates branch
  • The specific failing scenario(s) are identified from CI logs and fixed in actual code
  • No quality gate suppressions are used (no @skip, @xfail, threshold changes, # noqa, # type: ignore, etc.)
  • All 587 Behave BDD scenarios pass in the CI python:3.13-slim environment
  • A commit is created with message fix(ci): resolve unit_tests CI environment failure causing persistent ~6m45s timeout on branch fix/unit-tests-ci-environment-failure
  • A pull request is submitted, reviewed, and merged
  • All nox stages pass
  • Coverage >= 97%
  • #2597 — Parent Epic (CI quality gates restoration)
  • PR #2629 — Fix branch that has not yet resolved this failure

Label compliance fix applied:

  • Removed conflicting State/Verified (repo-level ID 1321) — issue had both State/Unverified and State/Verified simultaneously, which is contradictory.
  • Kept State/Unverified as this is a newly created issue that hasn't been triaged/verified yet.
  • Reason: Per CONTRIBUTING.md, each issue must have exactly one State/* label.

Note: This issue (#2850) is a child of #2597 (CI quality gates fix) and describes a Priority/Critical CI environment failure. It should be prioritized for triage.

Label compliance fix applied:

  • Added missing label: State/Verified
  • Reason: Issue was missing a State/* label per CONTRIBUTING.md. The issue has Priority/Critical and MoSCoW/Must have labels indicating it has been reviewed and is a known critical bug, so State/Verified is the appropriate state. The Blocked label indicates it is blocked but that is not a State/* label.

@freemo — This P0 blocker is being actively monitored by the Human Liaison supervisor [AUTO-HUMAN].

Current Impact:

  • Approximately 350 open PRs are blocked from merging until the unit_tests CI job passes
  • Milestone v3.2.0 is past due by 51 days (due 2026-02-26)
  • No releases can be cut while this remains unresolved

The autonomous implementation agents are aware of this blocker and are tracking it. The investigation path is well-defined in the issue subtasks:

  1. Obtain full CI logs for the most recent unit_tests failure on fix/master-ci-quality-gates
  2. Reproduce in the same python:3.13-slim Docker container used by CI
  3. Investigate parallel test isolation (race conditions in multiprocessing.Pool with fork start method)
  4. Check whether any @tdd_expected_fail scenario raises a non-AssertionError in CI (preventing tag inversion)
  5. Check CI-specific environment differences (missing packages, file permissions, SQLite behavior)

Could you provide an update on the investigation status, or indicate whether additional engineering resources should be directed here?

[AUTO-INF-SUP] P0 Investigation Update — 2026-04-18

PR #10214 Clarification

The supervisor was informed that PR #10214 was approved as a potential fix for this issue. This is incorrect. PR #10214 is a documentation PR about LLM provider fallback behavior ([AUTO-DOCS-7] docs: document LLM provider fallback behavior) and is not related to the unit_tests CI failure.

Current Status

  • PR #2629 was merged on 2026-04-05 (CI quality gates restoration)
  • Issue #2850 remains OPEN — unit_tests CI job is still failing
  • No fix PR exists for branch fix/unit-tests-ci-environment-failure
  • ⚠️ ~350 PRs are blocked from merging
  • ⚠️ Milestone v3.2.0 is 51 days overdue

Root Causes to Investigate

Per the issue description, the following root causes need investigation:

  1. ANSI escape codes from MCP health check warnings contaminating stdout in session tests
  2. Parallel test isolation issues (multiprocessing.Pool with fork start method)
  3. CI-specific environment differences (python:3.13-slim container)
  4. @tdd_expected_fail tag handling with non-AssertionError exceptions
  1. Obtain full CI logs from the most recent unit_tests job failure
  2. Reproduce the failure locally using the python:3.13-slim Docker container
  3. Create a PR against fix/unit-tests-ci-environment-failure with the fix
  4. Verify all 587 Behave scenarios pass in CI

This remains a P0 blocker requiring immediate engineering attention.
