test(viewer): Cypress 15 + run e2e against live deployments#252
Merged
Conversation
Bump cypress 14.3.2 → 15.18.0. Node 22 satisfies v15's engines
(^20.1 || ^22 || >=24) and none of v15's breaking changes touch how we
use it (no component testing, no cy.stub 3-arg, no SelectorPlayground).
v15 routing cy.url()/location()/title() through CDP/BiDi is a plus when
pointing at live cross-origin deployments. Test Replay comes for free on
`cypress run --record` (already used in CI).
Add `retries: { runMode: 2, openMode: 0 }` to absorb transient flake on
remote/live runs (network hiccups, async client-side deduction).
Verified 16/16 green in the hermetic path (local build + fixture).
Add a CYPRESS_ENV target axis that resolves both the base URL and a data
mode (fixture | live). local/CI stay hermetic (intercept the bundle with
main.min.json); deployed targets (pages, workers, graphs, preview) run
against the site's real R2 bundle, so we verify the actual deployments and
their cross-consistency.
- cypress.config.ts: resolveTarget() -> { baseUrl, mode }; expose mode via
Cypress.env. Workers URLs added; preview reads PREVIEW_URL (per-version).
- support: setup() intercepts only in fixture mode; add fixtureOnly() to
skip exact, fixture-pinned assertions on live runs.
- deduction/typesetting: move fixture-specific assertions (renumbered space
IDs, snapshotted KaTeX HTML) under fixtureOnly; data-stable deduction
checks still run live.
- bin/e2e: take targets (default pages+workers consistency check) and
health-check each; package scripts cy:run:{pages,workers,preview,graphs}.
- doc/testing.md: document fixture vs live and the target table.
Verified: hermetic 16/16; live pages and workers each 14 passed /
2 fixture-only skipped / 0 failed (identical).

These two specs were fixtureOnly because the curated fixture's space names had
drifted from live (live now embeds LaTeX, e.g. S000001 = "Discrete topology on
$\{0,1\}$"). Refresh the two tested spaces' display name/aliases (S000001,
S000004) to current live values and rewrite the assertions to hold in both
modes: a math-free name prefix for deduction, and a behavioral check (refs
resolve; embedded math is typeset via KaTeX) instead of an exact HTML snapshot
for typesetting. Drop the now-unused fixtureOnly helper.
NB: the fixture predates a pi-base property-ID reorganization, so its property
uids are NOT interchangeable with the live bundle's — only per-entity display
fields were refreshed (a bulk by-uid remap would corrupt the trait/theorem
corpus).
Verified: hermetic 16/16; live pages and workers each 16/16 (identical) — the
full suite now runs against the live deployments.

Reworks the viewer e2e suite so one set of specs can validate every deployment — local fixture, production Pages, and the new Workers site — and runs the deployed targets against their real R2 bundle to confirm Pages and Workers serve identical content. Supports the Workers migration. Also bumps Cypress 14 → 15.
CYPRESS_ENVpicks the target (and its data mode); default stayslocal/fixture, so CI is unchanged and hermetic.Review notes
