# Phase 14: DuckLake Integration Test Refresh and CI Job — Verification

**Status:** PASSED
**Verified:** 2026-03-02

## Phase Goal

Update the DuckLake integration test to v0.2.0 API, add a CI-runnable variant with inline synthetic data, wire a parallel CI job into PullRequestCI.yml, and add DuckLake compatibility checking to the DuckDB version monitor.

## Must-Haves Verification

### Truths

| Truth | Status | Evidence |
|-------|--------|----------|
| test_ducklake_helpers.py exists with shared helpers | PASS | File present, all 5 functions importable |
| test_ducklake_ci.py runs without jaffle-shop data | PASS | Creates DuckLake in tempfile.mkdtemp(), no fixture files |
| CI test covers 6 test cases | PASS | Tests 1-6 confirmed in file |
| Typed BIGINT assertion uses isinstance(int) | PASS | isinstance check confirmed in both test files |
| Time dimension returns datetime.date with known values | PASS | datetime.date assertions confirmed in test_ducklake_ci.py |
| test_ducklake.py uses only v0.2.0 API | PASS | No define_semantic_view or semantic_query in file |
| test_ducklake.py has 6 test cases | PASS | 12 "Test N:" patterns (6 print statements + 6 assertions = correct) |
| ducklake-ci-check parallel job in PullRequestCI.yml | PASS | Job present, no needs: dependency |
| DuckLake step in DuckDBVersionMonitor.yml | PASS | ducklake_test step with continue-on-error: true |
| PR bodies include DuckLake result | PASS | Both templates have DuckLake compatibility line |
| Justfile test-ducklake-ci target | PASS | Target present with test_ducklake_ci.py |
| test-all updated to include test-ducklake-ci | PASS | test-all: test-rust test-sql test-iceberg test-ducklake-ci |

### Artifacts

| Artifact | Status |
|----------|--------|
| test/integration/test_ducklake_helpers.py | PASS — exists |
| test/integration/test_ducklake_ci.py | PASS — exists |
| test/integration/test_ducklake.py | PASS — updated |
| .github/workflows/PullRequestCI.yml | PASS — ducklake-ci-check job added |
| .github/workflows/DuckDBVersionMonitor.yml | PASS — ducklake_test step added |
| Justfile | PASS — test-ducklake-ci target added |

### Key Links

| Link | Status |
|------|--------|
| test_ducklake_ci.py imports from test_ducklake_helpers | PASS |
| test_ducklake.py imports from test_ducklake_helpers | PASS |
| PullRequestCI.yml references test_ducklake_ci.py | PASS |
| DuckDBVersionMonitor.yml references test_ducklake_ci.py | PASS |

## Requirements Coverage

| Requirement | Status |
|-------------|--------|
| DUCKLAKE-CI (CI test + parallel job) | PASS |
| DUCKLAKE-LOCAL (local test v0.2.0 update) | PASS |
| DUCKLAKE-MONITOR (version monitor DuckLake step) | PASS |

## Conclusion

All must-haves verified. Phase 14 goal achieved. The DuckLake integration test is updated to v0.2.0 API, the CI test is self-contained, and the CI system now monitors DuckLake compatibility automatically.
