From 55410db0d8320f2c1d275452093190db8dae03db Mon Sep 17 00:00:00 2001 From: DevForge Engineer Date: Tue, 21 Jul 2026 17:41:17 -0400 Subject: [PATCH 1/2] fix(test): skip parquet tests when pyarrow unavailable (optional dep) Parquet tests failed in environments without a working pyarrow install (numpy binary incompatibility). Add requires_pyarrow skip marker that attempts actual import of pyarrow.parquet rather than just checking find_spec, so broken installs are correctly detected. 7 tests now skip gracefully; 134 pass. ruff check+format clean. --- tests/test_converters.py | 38 ++++++++++++++++++++------------------ 1 file changed, 20 insertions(+), 18 deletions(-) diff --git a/tests/test_converters.py b/tests/test_converters.py index a97a9d8..67fedfc 100644 --- a/tests/test_converters.py +++ b/tests/test_converters.py @@ -18,6 +18,18 @@ supported_formats, ) +try: + import pyarrow.parquet # noqa: F401 + + _HAS_PYARROW = True +except (ImportError, Exception): + _HAS_PYARROW = False + +requires_pyarrow = pytest.mark.skipif( + not _HAS_PYARROW, + reason="Parquet support requires pyarrow: pip install 'datamorph[parquet]'", +) + # ── Fixtures ────────────────────────────────────────────────────────── @@ -235,6 +247,7 @@ def test_yaml_to_csv(self, sample_yaml, tmp_path): # ── Parquet ─────────────────────────────────────────────────────────── +@requires_pyarrow class TestParquetConversion: def test_csv_to_parquet(self, sample_csv, tmp_path): output = tmp_path / "output.parquet" @@ -315,9 +328,7 @@ def test_avro_write_empty(self, tmp_path): def test_avro_nullable_first_row(self, tmp_path): """Avro should handle nullable fields even when the first row has nulls.""" path = tmp_path / "data.csv" - path.write_text( - "name,age,email\nAlice,,alice@test.com\nBob,30,\nCharlie,25,charlie@test.com\n" - ) + path.write_text("name,age,email\nAlice,,alice@test.com\nBob,30,\nCharlie,25,charlie@test.com\n") avro_file = tmp_path / "out.avro" result = convert(path, avro_file) assert not result.errors @@ -464,15 +475,14 @@ def test_convert_with_format_override(self, runner, sample_csv, tmp_path): assert result.exit_code == 0 assert "Converted" in result.output + @requires_pyarrow def test_convert_to_parquet(self, runner, sample_csv, tmp_path): output = tmp_path / "out.parquet" result = runner.invoke(cli, ["convert", str(sample_csv), str(output)]) assert result.exit_code == 0 def test_convert_nonexistent_input(self, runner, tmp_path): - result = runner.invoke( - cli, ["convert", "/nonexistent/file.csv", str(tmp_path / "out.json")] - ) + result = runner.invoke(cli, ["convert", "/nonexistent/file.csv", str(tmp_path / "out.json")]) assert result.exit_code != 0 def test_formats_command(self, runner): @@ -559,6 +569,7 @@ def test_batch_recursive(self, runner, tmp_path): # Verify nested directory structure is preserved assert any("nested" in str(f) for f in out_files) + @requires_pyarrow def test_batch_to_parquet(self, runner, sample_csv, tmp_path): """Batch convert CSV files to Parquet via CLI.""" output_dir = tmp_path / "pq_out" @@ -710,12 +721,7 @@ def test_large_json_array(self, tmp_path): class TestJsonlConversion: def test_jsonl_to_json(self, tmp_path): path = tmp_path / "data.jsonl" - path.write_text( - json.dumps({"name": "Alice", "age": 30}) - + "\n" - + json.dumps({"name": "Bob", "age": 25}) - + "\n" - ) + path.write_text(json.dumps({"name": "Alice", "age": 30}) + "\n" + json.dumps({"name": "Bob", "age": 25}) + "\n") output = tmp_path / "out.json" result = convert(path, output) assert not result.errors @@ -726,12 +732,7 @@ def test_jsonl_to_json(self, tmp_path): def test_jsonl_to_csv(self, tmp_path): path = tmp_path / "data.jsonl" - path.write_text( - json.dumps({"name": "Alice", "age": 30}) - + "\n" - + json.dumps({"name": "Bob", "age": 25}) - + "\n" - ) + path.write_text(json.dumps({"name": "Alice", "age": 30}) + "\n" + json.dumps({"name": "Bob", "age": 25}) + "\n") output = tmp_path / "out.csv" result = convert(path, output) assert not result.errors @@ -768,6 +769,7 @@ def test_jsonl_empty(self, tmp_path): class TestWriterKwargLeak: """Regression tests for delimiter kwarg leaking to non-CSV writers.""" + @requires_pyarrow def test_csv_delimiter_to_parquet(self, tmp_path): """csv_delimiter should not crash when converting to Parquet.""" csv_path = tmp_path / "data.csv" From cb3aa6afba53636471ac361fb38c720e34758308 Mon Sep 17 00:00:00 2001 From: DevForge Engineer Date: Tue, 21 Jul 2026 21:13:00 -0400 Subject: [PATCH 2/2] fix(ci): add missing checkout step to cowork-auto-pr.yml (gh pr create needs local repo) --- .github/workflows/cowork-auto-pr.yml | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/.github/workflows/cowork-auto-pr.yml b/.github/workflows/cowork-auto-pr.yml index 91690e6..b27f04e 100755 --- a/.github/workflows/cowork-auto-pr.yml +++ b/.github/workflows/cowork-auto-pr.yml @@ -12,6 +12,14 @@ jobs: ensure-pr: runs-on: ubuntu-latest steps: + # gh pr create requires a local git checkout to diff head against base;
