That batch-style harness made browser↔R round-trip flows hard to express: each step has to know its position in a pre-baked Rscript, and resize/history regressions ended up depending on fixed sleeps to align browser and R.\n\nThis PR moves the E2E tests to an `arf ipc`-driven session model so a single test can explicitly interleave:\n\n1. an R-side draw or `library(jgd); jgd(...)` call,\n2. a browser action (resize, plotIndex resize, navigation),\n3. an R-side `.Call(jgd:::C_jgd_poll_resize)` / replay step,\n4. an assertion against the WebSocket frame or canvas.\n\nIt also adds dedicated regression coverage for historical-plot resize and a few previously-flaky scenarios that the new harness can finally express cleanly.\n\n## What changed\n\n### Harness\n- **`tests/helpers/arf_session.ts`** — new `ArfSession` class wrapping `arf headless` + `arf ipc eval/shutdown` with explicit startup, eval, and shutdown lifecycle. Failures during startup (timeout, invalid ready JSON, spawn errors) tear the child down rather than leak it, and shutdown still kills the headless process even when `arf ipc shutdown` cannot be spawned.\n- **`tests/helpers/arf_e2e.ts`** — shared `startArfBrowserTest` / `startArfPageTest` setup contexts, `sendResizeAndPoll` / `sendPlotIndexResizeAndPoll` helpers, and `assertNoExtraFrameBeforePong` for negative assertions. Cleanup runs even when setup fails partway through.\n- **`tests/helpers/arf_poll.ts`** — small `pollResize(arf, iterations)` helper so tests don't duplicate the same `for (i in 1:N) { .Call(jgd:::C_jgd_poll_resize); Sys.sleep(0.005) }` loop.\n- **`tests/helpers/r_process.ts`** — `runR`/`startR` removed. Only the socket-address helper and the R-availability check remain.\n\n### Deterministic resize synchronization\n- Resize tests no longer rely on `await delay(100)` before `po", "time": 1778806524 }, "_maintainer": { "name": "Grant McDermott", "email": "contact@grantmcdermott.com" }, "_registered": true, "_dependencies": [ { "package": "callr", "role": "Suggests" }, { "package": "ggplot2", "role": "Suggests" }, { "package": "jsonlite", "role": "Suggests" }, { "package": "processx", "role": "Suggests" }, { "package": "testthat", "version": ">= 3.0.0", "role": "Suggests" }, { "package": "withr", "role": "Suggests" } ], "_owner": "grantmcdermott", "_selfowned": true, "_usedby": 0, "_updates": [ { "week": "2026-06", "n": 24 }, { "week": "2026-07", "n": 31 }, { "week": "2026-08", "n": 5 }, { "week": "2026-09", "n": 14 }, { "week": "2026-10", "n": 2 }, { "week": "2026-12", "n": 7 }, { "week": "2026-13", "n": 6 }, { "week": "2026-14", "n": 3 }, { "week": "2026-17", "n": 3 }, { "week": "2026-18", "n": 5 }, { "week": "2026-19", "n": 2 }, { "week": "2026-20", "n": 1 } ], "_tags": [ { "name": "nightly", "date": "2026-04-29" }, { "name": "v0.1.0", "date": "2026-04-29" } ], "_stars": 46, "_contributors": [ { "user": "eitsupi", "count": 308, "uuid": 50911393 }, { "user": "grantmcdermott", "count": 70, "uuid": 10285037 } ], "_userbio": { "uuid": 10285037, "type": "user", "name": "Grant McDermott", "description": "Principal Economist at Amazon.
