Add test coverage for high-level and low-level executor functions

[Copilot]

The repository had no test coverage for the executor lambda functions. This adds comprehensive unit tests for both the high-level handle_event() orchestration and all six low-level executor functions.

Changes

• High-level tests (4): handle_event() success/error paths, ARN parsing, exception propagation
• Executor initialization (2): AWS Secrets Manager integration, error handling
• Executor execution (2): Function routing validation, unrecognized function handling
• Low-level executor functions (9): All six executor methods with success/error cases:
  • import_GOES_data_to_timestream()
  • create_GOES_data_annotations()
  • generate_cloc_report_and_upload()
  • import_UDL_REACH_to_timestream()
  • import_stix_to_timestream()
  • get_padre_orbit_data()
• Lambda handler (2): Entry point proxy behavior

Test Structure

Tests use mocking to eliminate external dependencies:

@patch('executor.executor.util.record_timeseries')
@patch('stixdcpy.quicklook.LightCurves.from_sdc')
def test_import_stix_to_timestream_with_data(self, mock_lightcurves, mock_record):
    """Test STIX data import with data."""
    mock_lc = Mock()
    mock_lc.data = True
    mock_lc.time = Time(["2024-01-01T00:00:00", "2024-01-01T00:01:00"])
    mock_lc.counts = [[1.0, 2.0], [3.0, 4.0]]
    mock_lightcurves.return_value = mock_lc
    
    Executor.import_stix_to_timestream()
    
    mock_lightcurves.assert_called_once()
    mock_record.assert_called_once()

Total: 19 tests, 62% coverage

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• services.swpc.noaa.gov
  • Triggering command: /usr/bin/python python -m pytest tests/test_executor.py -v /tmp/pip-installHEAD et-metadata_23e8032c8bfd45e98bec7a5f7aaad13a/ ease (dns block)
  • Triggering command: /usr/bin/python python -m pytest tests/test_executor.py::TestExecutorExecute::test_execute_valid_function -v 9de0444/.git 2254e65b37a5d9a1-n al/local/bin/git1 --untracked-filegit (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
