Pytest Generation Skill

When generating tests, follow this structure.

Test Organization

Group tests by function under test
Use @pytest.mark.parametrize for multiple inputs
Use fixtures for shared setup
Follow arrange/act/assert pattern

Coverage Requirements

Happy path (expected usage)
Edge cases (empty strings, None, boundary values)
Error cases (invalid input, file not found, wrong types)
Integration (functions working together)

Template

import pytest
from module_under_test import function_to_test


@pytest.fixture
def sample_data():
    """Provide shared test data."""
    return {"key": "value"}


class TestFunctionName:
    """Tests for function_name."""

    def test_happy_path(self, sample_data):
        result = function_to_test(valid_input)
        assert result == expected_output

    def test_empty_input(self):
        result = function_to_test("")
        assert result == expected_for_empty

    @pytest.mark.parametrize("input_val,expected", [
        ("valid", True),
        ("", False),
        (None, False),
    ])
    def test_various_inputs(self, input_val, expected):
        assert function_to_test(input_val) == expected
