From 33570d76907ac2512ad7fc8f45138678985b0e00 Mon Sep 17 00:00:00 2001 From: davidmonterocrespo24 Date: Fri, 15 May 2026 22:11:28 +0200 Subject: [PATCH] =?UTF-8?q?feat(sim):=20Phase=201d=20#1=20=E2=80=94=20gall?= =?UTF-8?q?ery=20smoke=20test=20imports=20real=20examples=20+=20shared=20h?= =?UTF-8?q?elper?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the manual "open each example in browser" step from the post-migration plan with an automated test that: • Imports `analogExamples` and `digitalExamples` from the real `data/examples-*.ts` modules — new gallery entries pick up the test automatically. • Uses the same `stripBrandPrefix` + board-filter logic that production `loadExample.ts` uses, via the new shared helper `utils/exampleToBuildNetlistInput.ts`. Single source of truth: if the wokwi/velxio prefix rule ever changes, both production and the smoke test track it. • Runs each example through `solveInput` (Phase 1c F2 helper) against the same ngspice WASM production uses. `loadExample.ts` refactored to call `stripBrandPrefix` instead of inlining the regex (two call sites converged on the helper). Result against the gallery: • 67/68 examples converge cleanly. • 1 known regression: `an-opamp-follower` (LM358 follower) — the same case `examples-analog-live.test.ts` already skips. Item #2 (.op convergence helpers in NgSpiceWorkerAdapter) targets it. The smoke test now serves as the safety net for the remaining post-migration work — it'll flag if a future fix breaks examples that converge today.
