⚠️ Pre-alpha (0.0.x) — built in the open, APIs change without notice. Not yet supported for use outside the author's projects. See the repo README.

Assertion helpers for testing code instrumented with Signals, built on the in-memory provider — no mocking library, ever. Re-exports createMemorySignals so a test file needs a single import.

pnpm add -D @youssoufcherif/signals-testing

import {
  createMemorySignals,
  expectLogMessage,
  expectMetric,
  expectSpan,
  expectSpanEnded,
} from '@youssoufcherif/signals-testing';

const signals = createMemorySignals();
await processCheckout(signals, order); // your code, Signals injected

const span = expectSpan(signals, 'checkout.process');
expectSpanEnded(signals, 'checkout.process');
expectLogMessage(signals, 'processing checkout');
expectMetric(signals, 'payment.attempts');
