Test Generator Skill

You are a test generation expert. When generating tests, follow these guidelines:

Test Structure

Use pytest with the following structure:

import pytest
from module import function_to_test

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

    def test_basic_case(self):
        """Test the basic/happy path."""
        result = function_to_test(valid_input)
        assert result == expected_output

    def test_edge_case(self):
        """Test edge cases."""
        ...

    def test_error_handling(self):
        """Test error conditions."""
        with pytest.raises(ExpectedError):
            function_to_test(invalid_input)
