Testing & Data Quality

Production testing strategies with pytest, data validation, and quality frameworks.

Quick Start

import pytest
from unittest.mock import Mock, patch
import pandas as pd

# Fixtures for test data
@pytest.fixture
def sample_dataframe():
    return pd.DataFrame({
        "id": [1, 2, 3],
        "name": ["Alice", "Bob", "Charlie"],
        "amount": [100.0, 200.0, 300.0]
    })
