Detailed Description

Unit tests for the pre-index run summary, and the contract that opening a run is cheap.

The point of this module is that selecting a run must not trigger a parquet export, so
the tests assert the absence of work as much as the presence of numbers.

Run: cd webviewer && .venv/bin/python -m pytest backend/test_summary.py -q

Function Documentation

◆ run_dir()

backend.test_summary.run_dir	(		tmp_path,
			monkeypatch )

A fake run laid out the way elodin-db lays one out: a numeric directory per
component, each holding data/index/metadata/schema, plus non-component siblings.

Definition at line 19 of file test_summary.py.

◆ test_a_run_with_no_components_still_summarizes()

backend.test_summary.test_a_run_with_no_components_still_summarizes	(		tmp_path,
			monkeypatch )

Definition at line 72 of file test_summary.py.

◆ test_components_refuses_an_unindexed_run_rather_than_exporting()

backend.test_summary.test_components_refuses_an_unindexed_run_rather_than_exporting	(		run_dir,
			monkeypatch )

GET /components used to export on demand, which made merely clicking a run in the
list cost tens of seconds. It now refuses; POST /index is the way to pay that.
