test_analysis_utils

Create a mock BuildInput object.

Create a temporary simulation directory structure.

Test basic discovery of simulations.

Test with no valid directories.

Test directory missing required files.

Test directory with no YAML files.

Test error when multiple valid YAML files exist.

Test handling of invalid YAML files.

Test with custom trajectory and structure filenames.

Test with string path instead of Path object.

Test discovery across multiple simulation directories.

Test flatten_species_composition returns expected keys.

Test flatten_system_parameters merges system_specific metadata.

Test ValueError raised for invalid min_status.

Test STATUS_ORDER contains expected values in correct order.

Test that min_status defaults to 'production' (backward compatibility).

Test min_status='build' includes simulations without trajectory.

Test min_status='completed' excludes non-completed simulations.

Test status column returns correct status values based on files.

Test that simulations below min_status threshold are excluded.

Build a minimal object that satisfies trajectory_window's interface.

No start_ns or last_ns returns the full trajectory.

start_ns crops the beginning of the trajectory.

last_ns selects the trailing portion of the trajectory.

last_ns takes precedence when both are provided.

stride is passed through as the step value.

start_ns past the end clamps to total_frames.

end_ns caps the stop frame.

end_ns=None returns full trajectory (default).

start_ns and end_ns together define a sub-window.

end_ns past the end clamps to total_frames.

Ragged per-frame outputs should be returned as a Python list.
