//! Comprehensive TDD tests for rtx-sklearn-py Python wrappers
//! Following strict Test-Driven Development with red-green-refactor methodology
//!
//! NOTE: These tests are designed for PyO3-wrapped Python classes.
//! The wrappers in rtx-sklearn-py are Python bindings that must be tested
//! through Python integration tests or using pyo3::Python::with_gil.
//!
//! For proper testing of the Python API, use pytest-based tests.

// TODO: Add proper Python-based integration tests
// These should be in tests/python/ and use pytest
// Example structure:
// ```python
// import pytest
// from rustytorch_ml import (
//     DecisionTreeClassifier,
//     LinearRegression,
//     KMeans,
//     StandardScaler,
//     GridSearchCV,
// )
//
// def test_decision_tree_wrapper():
//     dt = DecisionTreeClassifier(max_depth=5)
//     assert dt.max_depth == 5
//
// def test_linear_regression_wrapper():
//     lr = LinearRegression(fit_intercept=True)
//     assert lr.fit_intercept == True
//
// # ... more Python tests
// ```
