@invinite-org/chartlang-conformance

experimental

Adapter conformance suite. It compiles bundled scenarios, runs them through the runtime against a target adapter's capabilities, and asserts pinned plot, drawing, alert, and diagnostic outcomes.

Install

pnpm add -D @invinite-org/chartlang-conformance

Public surface

• runConformanceSuite(adapter, opts?) -> Promise<ConformanceReport> drives every bundled scenario or an injected scenario subset.
• ScenarioAssertion covers plot-hash, drawing-hash, alert counts/messages, and diagnostic present/absent assertions.
• ALL_SCENARIOS includes Phase 1 smoke coverage, Phase 2 TA ports, Phase 3 drawing parity, and Phase 4 scenarios for state, tick state, barstate, syminfo, timeframe, inputs, request.security NaN fallback, and unsupported intervals.
• generateGoldenBars(), serialiseGoldenBars(), writeGoldenBars(path), and GOLDEN_BARS_PATH provide the deterministic 10 000-bar fixture.

Minimum-viable API call

import { runConformanceSuite } from "@invinite-org/chartlang-conformance";
import myAdapter from "./my-adapter";

const report = await runConformanceSuite(myAdapter);
if (report.failed > 0) throw new Error(report.failures[0]?.message ?? "failed");
