  • Commit Message: test: add TDD bug-capture test for #992 — DI container audit cache failure
  • Branch: tdd/m6-di-audit-cache-failure

Background and Context

This is the TDD counterpart to bug #992. Per the project's Test-Driven Development workflow for bugs (see CONTRIBUTING.md > Bug Fix Workflow), the first step in fixing any bug is to write a test that captures the buggy behavior. The test is tagged with @tdd_bug, @tdd_bug_992, and @tdd_expected_fail so that it passes CI while the bug is still unfixed. Once the fix is implemented in #992, the @tdd_expected_fail tag will be removed and the test will run normally.

See #992 for full bug details.

Expected Behavior

A new test exists that:

  1. Captures the exact failure described in #992.
  2. Is tagged with @tdd_bug, @tdd_bug_992, and @tdd_expected_fail.
  3. Passes CI via the expected-failure mechanism (the underlying assertion fails, confirming the bug exists, but the tag inversion causes the test to pass).
  4. Would fail CI if the bug were fixed without removing the @tdd_expected_fail tag.

Acceptance Criteria

  • A test is written that captures the bug behavior described in #992.
  • The test is tagged with @tdd_bug, @tdd_bug_992, and @tdd_expected_fail.
  • The @tdd_expected_fail tag causes the test to pass CI (the underlying assertion fails as expected, proving the bug exists).
  • The test is specific enough that it will pass normally (without the tag) only when the bug is genuinely fixed.
  • Tag validation rules pass: @tdd_bug_992 has corresponding @tdd_bug, and @tdd_expected_fail has both.
  • A pull request is opened from the branch to master, CI passes, and the PR is merged through the normal merge process.

Definition of Done

This issue is complete when:

  • All subtasks below 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 test and what bug behavior it captures.
  • 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, CI passes, and the PR is merged before this issue is marked done.

Subtasks

  • Code: Analyze bug #992 to identify the exact failure condition, including the inputs, state, and code path that trigger the bug.
  • Code: Determine the appropriate test type (Behave unit test, Robot integration test, or both) and file location for the reproducing test.
  • Tests (Behave): Write a Behave scenario in features/ that captures the bug. Tag the scenario with @tdd_bug, @tdd_bug_992, and @tdd_expected_fail. The scenario must exercise the specific code path that triggers the bug and assert the correct expected behavior (which currently fails due to the bug). Name the scenario descriptively to indicate it is a bug regression test.
  • Tests (Robot): N/A — bug #992 is unit-level DI container singleton behavior (get_container() retry path), so Behave is the appropriate layer; no additional Robot integration test is required to reproduce the defect.
  • Docs: Add a comment in the test file explaining this test captures bug #992 and uses @tdd_expected_fail until the fix is merged.
  • Quality: Verify CI passes with the tagged test. Confirm the underlying assertion fails for the correct reason.
  • Quality: Verify tag validation rules pass.
  • Quality: Verify coverage >=97% via nox -s coverage_report. If coverage is <97% then review the current unit test coverage report at build/coverage.xml and use it to write new Behave based unit tests to improve code coverage.
  • Quality: Run nox (all default sessions), fix any errors if needed ensuring nox passes across entire code base.

Phase 2 implementation note (analysis + test design):

  • Reviewed bug ticket #992 and confirmed the exact failure path in cleveragents.application.container.get_container.
  • Current behavior in get_container():
    1. If _container is None, instantiate Container()
    2. Attempt _container.audit_event_subscriber() once inside try/except
    3. On exception, log warning and continue
    4. Return _container
  • Because _container remains set after the first failure, future calls skip the initialization block entirely. This reproduces the bug statement that audit subscriber initialization is effectively cached in failed state for long-lived processes.

Design decisions for the reproducing test:

  • Test type: Behave only (unit-level behavior in DI bootstrap path). Robot test is not needed for this issue because no integration boundary is required to reproduce this defect.
  • New feature file: features/tdd_di_audit_cache_failure.feature
  • New step file: features/steps/tdd_di_audit_cache_failure_steps.py
  • Tagging strategy: @tdd_bug @tdd_bug_992 @tdd_expected_fail on the scenario.
  • Reproduction mechanism in steps:
    • Patch container.Container to a fake container whose audit_event_subscriber() fails once, then succeeds.
    • Call get_container() twice.
    • Assert initialization attempts should be 2 (expected correct behavior), which currently fails (actual is 1), proving bug #992 is present.

I’m proceeding with the failing-scenario implementation and then running nox quality gates.

Phase 2/3 implementation journal update:

Implemented files

  • features/tdd_di_audit_cache_failure.feature
  • features/steps/tdd_di_audit_cache_failure_steps.py

Behavior captured

  • The test patches cleveragents.application.container.Container with a deterministic fake container.
  • Fake behavior:
    • audit_event_subscriber() raises on first call (simulates startup DB-not-ready path)
    • subsequent call succeeds
  • Scenario then calls get_container() twice and asserts two initialization attempts should have occurred.
  • Current implementation performs only one attempt (inside first-creation branch), so the underlying assertion fails with:
    • "Expected 2 attempts ... observed 1"
  • Because the scenario is tagged @tdd_expected_fail @tdd_bug @tdd_bug_992, this failing assertion is inverted to a passing CI outcome while the bug remains unfixed.

Rationale

  • This is the minimal unit-level repro for #992 and directly exercises the problematic control flow in get_container().
  • A Robot integration duplicate would be redundant for this specific defect because no external integration dependency is required to reproduce the logic bug.

Quality gates executed

  • nox -e lint
  • nox -e typecheck
  • nox -e unit_tests
  • nox -e integration_tests
  • nox -e e2e_tests (note: first run had transient M2 acceptance failure; immediate re-run passed fully)
  • nox -e coverage_report
    • coverage from build/coverage.xml: line-rate 0.9767 (97.67%)
  • nox (full default suite)

Traceability notes

  • Bug path under test: cleveragents.application.container.get_container
  • New test logical references:
    • feature spec: features/tdd_di_audit_cache_failure.feature
    • step logic: features.steps.tdd_di_audit_cache_failure_steps

Ready for Phase 4 (commit/push) and Phase 5 (PR + In Review transition).

PR #1164 Review Outcome: REQUEST CHANGES (Obsolete)

PR #1164 has been reviewed and marked as REQUEST_CHANGES — the PR is obsolete and cannot be merged.

Reason

The TDD test files introduced by PR #1164 already exist on master, delivered via commit a0c6ecd3 ("fix(di): get_container() permanently caches failed audit subscriber in Singleton provider"). That fix commit included the same TDD test with @tdd_expected_fail correctly removed.

Merging PR #1164 would:

  1. Cause merge conflicts (both files already exist on master with different content)
  2. Reintroduce @tdd_expected_fail on a now-passing test, breaking CI

Recommendation

PR #1164 should be closed without merging. The deliverable for this issue (TDD test capturing bug #992) is already on master. This issue should be transitioned to State/Completed.

PR #1164 has been reviewed and marked as REQUEST CHANGES — the PR is obsolete and cannot be merged.

Reason: The TDD test files introduced by PR #1164 already exist on master, delivered as part of the production fix for bug #992. The PR has unresolvable merge conflicts (mergeable: false), and the @tdd_expected_fail tag in the PR would break CI since the bug is now fixed.

Recommendation: Close PR #1164 without merging. The deliverable for this issue (the TDD test capturing bug #992) is already on master in its correct final form. This issue should be transitioned to State/Completed.
