Tests

Plain scripts. They print OK or NO, count at the end, and exit non-zero if anything failed. No pytest, no fixtures, no configuration.

python3 check_rules.py       # 147 — the Radiopaedia linter rules
python3 check_structure.py   #  24 — the article structures
python3 check_search.py      #  85 — query building, ISSG, strategies, lists
python3 check_journals.py    #  74 — SCImago, matching, Unpaywall, backups
python3 check_app.py         #  89 — the interface, driven without a browser

419 checks. None of them needs the network, and none touches a real archive: each script points RADIOPAEDIA_DB at a throwaway file before importing db.

The one that needs the network

python3 check_mesh_live.py

It asks PubMed whether every MeSH descriptor and subheading in strategies.py still exists. Run it when you change the strategies, and once a year when MeSH is updated in January. It needs the NCBI email to be set in the app.

check_app.py

The other scripts test the engines. This one tests the wire between them and the interface, which is where the mistakes live that an engine cannot make.

streamlit.testing.v1.AppTest runs the real app in memory and lets you press buttons by key, so what is exercised is exactly the code that ships:

at = AppTest.from_file(APP, default_timeout=60)
at.run()
at = next(t for t in at.toggle if t.key == "sf_recent").set_value(False).run()
is_("switching it off unlocks the filters",
    next(n for n in at.number_input if n.key == "sf_years").disabled, "False")

Two real bugs were caught this way and could not have been caught otherwise: a sqlite3.Row passed as a widget option, which is unpicklable and took the whole page down, and a write to session_state after the widget existed.

Note that st.caption output is in at.caption, not at.markdown.

What CI runs

.github/workflows/test.yml, on macOS, Linux and Windows against Python 3.11 and 3.13. It runs the five scripts, then starts the installed command and asks /_stcore/health — because nothing else exercises the entry point, and the entry point is what breaks only once it is installed.
