Commit: N/A — static analysis finding
Branch: main

Background and Context

The BDD test suite (634 feature files, 821 step files) contains 445 bare pass statements in step implementations and 7 assert True statements. These represent test steps that execute no meaningful assertions, providing false confidence in test coverage metrics.

Many feature files appear to be "coverage boost" files (e.g., a2a_clients_coverage_boost.feature, acms_service_coverage_boost.feature, coverage_boost_extra.feature) that exist primarily to increase line coverage metrics rather than verify behavior. The step implementations for these often use pass or assert True.

Additionally, the test suite has 634 feature files but only 8 actual test_*.py files (none in the src/ directory), with no unit tests for critical paths such as error propagation, concurrent access patterns, TOCTOU race conditions, and boundary conditions in plan lifecycle state machine transitions.

Expected Behavior

All BDD step implementations contain meaningful assertions that verify actual behavior
No assert True statements exist in the test suite (they verify nothing)
Bare pass statements in step implementations are either replaced with real assertions or explicitly marked as @skip with a documented reason
A CI check prevents assert True from appearing in test files
Coverage metrics accurately reflect behavioral test coverage, not hollow step execution

Acceptance Criteria

All 7 assert True occurrences are replaced with meaningful assertions
All 445 bare pass step implementations are audited; each is either given a real assertion or explicitly marked @skip with a documented reason
A CI lint/check is added that fails if assert True appears in any features/steps/*.py file
"Coverage boost" feature files are distinguished from behavioral tests (e.g., via tags or directory separation)
Unit tests are added for at least the following critical paths: lock service concurrent access, phase gating TOCTOU conditions, plan lifecycle state machine boundary transitions
nox passes with coverage >= 97% after the above changes

Definition of Done

This issue should be closed when:

All 7 assert True occurrences have been replaced with meaningful assertions
All 445 bare pass step implementations have been audited and either given real assertions or explicitly marked @skip with documented reasons
A CI check is in place that prevents future assert True additions
Unit tests exist for the identified critical paths
nox passes with coverage >= 97%
A PR has been reviewed and merged to main

Summary

Scale

445 bare pass statements in features/steps/*.py files
7 assert True statements — trivially passing assertions that verify nothing
2387 MagicMock/Mock() usages — heavy mocking that may not test real behavior

`assert True` Occurrences (Trivially Passing)

# features/steps/aimodelsproviders_steps.py:482,612
assert True  # verifies nothing

# features/steps/coverage_boost_extra_steps.py:662
assert True

# features/steps/legacy_migrator_steps.py:922,940,1007
assert True

# features/steps/stream_router_remaining_coverage_steps.py:530
assert True

Bare `pass` in Step Implementations (Sample)

# features/steps/a2a_clients_coverage_boost_steps.py:32,38,44
@then("...")
def step_impl(context):
    pass  # no assertion

# features/steps/output_rendering_steps.py (50+ occurrences)
@then("the output should contain ...")
def step_impl(context):
    pass  # never verified

# features/steps/uko_indexer_protocol_steps.py (20+ occurrences)
@then("...")
def step_impl(context):
    pass

Files with Most Hollow Steps

File	Bare `pass` Count
`output_rendering_steps.py`	50+
`uko_indexer_backend_steps.py`	30+
`temporal_data_model_*.py`	40+ combined
`uko_runtime_steps.py`	15+
`crp_models_steps.py`	15+
`scoped_view_steps.py`	15+

Coverage Inflation Risk

Missing Edge Case Testing

The test suite has 634 feature files but only 8 actual test_*.py files (none in the src/ directory). There are no unit tests for:

Error propagation through the exception hierarchy
Concurrent access patterns in lock_service.py
TOCTOU race conditions in phase_gating.py
Boundary conditions in plan lifecycle state machine transitions

Impact

Coverage metrics are inflated by hollow tests
Real bugs may pass CI because step implementations don't assert
assert True provides zero regression protection
The 2387 Mock usages may be testing mock behavior rather than real behavior

Recommendation

Audit all assert True occurrences and replace with meaningful assertions
Audit all bare pass step implementations and add assertions or mark as @skip
Add a CI check that fails if assert True appears in test files
Distinguish "coverage boost" tests from behavioral tests
Add unit tests for critical paths: lock service, phase gating, plan lifecycle state machine

Assessment

High-priority test quality issue. 445 bare pass statements and 7 assert True occurrences provide false confidence in coverage metrics.

Triage Decision

Status: Verified - issue is legitimate and actionable
Priority: High - hollow tests mask real regressions
Recommended milestone: v3.2.0

Next Steps

Fix all 7 assert True occurrences first
Replace bare pass step implementations with real assertions or @skip markers
Add CI lint check to prevent future assert True additions
Add unit tests for lock service, phase gating, plan lifecycle state machine
