From 70c2ccba3dabd73b5540eee9ee028e1eefee406d Mon Sep 17 00:00:00 2001 From: Louis Lambeau Date: Thu, 2 Apr 2026 14:28:57 +0200 Subject: [PATCH 1/9] Improve test coverage and fix RAW mode runner bug Fix a bug in JobRunner where RAW mode crashed because updateMetrics() was called without null checks in the promise resolution/rejection handlers of #doRun. Replace broken proxyquire usage in consumer, server, and REST API tests with direct imports and sinon stubs. Add tests for: runner RAW mode (7 tests), NodeJSRunner RAW mode (unskip), dispatcher invalidJobExchange path, dispatcher queue push failures, consumer stop() and multi-config, and server stop(). Test count goes from 219 passing + 1 failing to 251 passing + 0 failing.

Arnavon.cwd() and Arnavon.require() are marked @deprecated.

Defines TypeScript interfaces for JobDefinition, ConsumerDefinition, QueueDefinition, and ArnavonOptions. JobValidator now accepts either a Finitio.System or a plain validator function (data) => data, enabling Zod/Joi/custom validation. ConsumerConfig accepts a handler function as alternative to runner config. FunctionRunner wraps the handler with the same metrics/lifecycle as other runners. New exports: ValidatorFn, HandlerFn, ArnavonOptions, JobDefinition, ConsumerDefinition, QueueDefinition, RunnerDefinition. 321 passing tests (12 new), 0 failing.

charset=UTF-8 Content-Transfer-Encoding: 8bit When using ArnavonApp (which has its own registry and doesn't set the Arnavon singleton), Consumer._startConsuming() created runners via JobRunner.factor() without passing a registry. The runner constructor fell back to Arnavon.registry which was undefined, causing a crash. Now Consumer passes its registry through factor() → RunnersFactory → runner constructor.
