Module testing

Example

import {
  // Builders
  connect, connack, publish, subscribe,
  // Harness
  TestHarness, createTestHarness,
  // Generators
  arbPublishPacket, arbChunkSplits,
  // Fixtures
  fixtures, fromHex
} from "@qualithm/mqtt-wire/testing"

// Build packets fluently
const packet = publish("sensors/temp").payload("22.5").qos(1).packetId(1).build()

// Test with harness
const harness = createTestHarness()
await harness.wire.connect({ clientId: "test" })

// Property-based testing
fc.assert(fc.property(arbPublishPacket, (packet) => {
  const encoded = encodePacket(packet)
  const decoded = decodePacket(encoded)
  return decoded.ok
}))

// Use spec fixtures
for (const fixture of fixtures.publish) {
  expect(encodePacket(fixture.packet)).toEqual(fixture.bytes)
}
