pytest-ditto-pyarrow
A pytest-ditto plugin for PyArrow Table snapshots.
Installation
pip install "pytest-ditto[pyarrow]"
Marks
@ditto.pyarrow.parquet@ditto.pyarrow.feather@ditto.pyarrow.csv
Each mark is shorthand for @ditto.record("<name>").
Use @ditto.pyarrow.parquet or @ditto.pyarrow.feather: CSV loses types
and can drop rows. See the format notes in the documentation.
Usage
import pyarrow as pa
import pyarrow.compute as pc
import ditto
import pytest
@pytest.fixture
def table() -> pa.Table:
return pa.table(
[
[1, 2, 3, 4],
[4.5, 5.2, 6.8, 3.5],
[7, 8.5, None, None],
[True, False, True, True],
["a", "b", "c", "x"],
],
names=list("abcde"),
)
def fn(x: pa.Table):
even_filter = pc.bit_wise_and(pc.field("a"), pc.scalar(1)) == pc.scalar(0)
return x.filter(even_filter)
@ditto.pyarrow.parquet
def test_fn_with_pyarrow_parquet_snapshot(snapshot, table):
result = fn(table)
assert result.equals(snapshot(result, key="filtered"))
