| 1 | //! The oracle harness's driver: the bounded corpus, the two compiles, and the comparisons between them. |
| 2 | //! |
| 3 | //! "Oracle" here is the installed `typst` binary: for each corpus root, the same `.typ` source is |
| 4 | //! compiled once by it and once by the built `austenite` binary ([`env!("CARGO_BIN_EXE_austenite")`], |
| 5 | //! Cargo's own path to the package's compiled binary, so the test exercises the real artefact rather |
| 6 | //! than re-implementing its pipeline). What is compared is deliberately narrow -- page counts, and each |
| 7 | //! heading's and figure's resolved page, order-matched rather than matched by name, since Austenite's |
| 8 | //! own anchor keys are synthesised from a running count and a title slug ([`doc.rs`]'s `AnchorId::new` |
| 9 | //! calls), not read back from the document's own Typst labels. A raster sample adds a coarse visual |
| 10 | //! sanity check where ImageMagick is installed. |
| 11 | //! |
| 12 | //! Every external tool -- `typst`, `pdfinfo`, `pdftoppm`, `compare`, `identify`, `sha256sum` -- is |
| 13 | //! invoked by [`std::process::Command`], never linked in: a missing or incompatible `typst` (see |
| 14 | //! [`corpus`]'s doc comment on the `oxeweb-techspec` root) downgrades that root's oracle comparison to a |
| 15 | //! recorded note rather than failing the whole suite, since the Austenite-only side -- did it compile, |
| 16 | //! how many pages, how many anchors -- is still a real regression signal on its own. |
| 17 | //! |
| 18 | //! Three invariants beyond the page/anchor comparison are recorded into the baseline |
| 19 | //! ([`Baseline`]/[`BaselineEntry`]) and asserted against it, not against a fixed magic number: the |
| 20 | //! rendered PDF's SHA-256 (byte-identity -- did austenite's OWN output move at all), and the worst of |
| 21 | //! three sampled pages' raster diff against the Typst oracle (did austenite's output stop LOOKING like |
| 22 | //! Typst's). Both are gated by the same accept switch: a run that finds either has moved from its |
| 23 | //! recorded baseline fails, unless `ORACLE_ACCEPT=1` is set, in which case the new value is re-recorded |
| 24 | //! and printed rather than silently accepted -- see [`record_and_diff`] and [`BaselineOutcome`]. |
