S3 — Generate Tests for $ARGUMENTS

Generate a comprehensive pytest test suite for the module at $ARGUMENTS.

Project Test Configuration

!`cat pyproject.toml | grep -A 15 '\[tool.pytest'`

Existing Test Files

!`ls tests/`

Instructions

1. Read the target module at $ARGUMENTS to understand its public API
2. Generate tests following these patterns:

Test Structure (AAA Pattern)

class TestFunctionName:
    def test_happy_path(self):
        # Arrange
        input_data = ...
        # Act
        result = function_name(input_data)
        # Assert
        assert result == expected

    def test_edge_case(self):
        ...

    def test_error_case(self):
        with pytest.raises(ValueError):
            function_name(bad_input)

Requirements

• One class per public function, named TestFunctionName
• Use @pytest.fixture for shared setup (especially clearing in-memory stores)
• Use @pytest.mark.parametrize for input variants
• Test happy path, edge cases, and error cases
• Use autouse=True fixtures for store cleanup
• Match the naming and style of existing tests in tests/

3. Write the test file to tests/test_<module_name>.py
4. Run the tests to verify they pass
