Serverless Queue Testing Patterns: Inngest vs Trigger.dev vs BullMQ Compared

Modern background job systems differ fundamentally in their execution model, and those differences shape how you test them. Inngest replays your entire function body on each step. Trigger.dev executes tasks as isolated units. BullMQ processes jobs as single-invocation functions with Redis-backed state. Getting your testing strategy wrong

BullMQ Advanced Testing: Flow Producers, Delayed Jobs, and Rate Limiters

BullMQ's advanced features — flow producers, delayed jobs, rate limiters, and job groups — enable sophisticated background processing patterns. But these features are also the hardest to test correctly. This guide covers testing strategies for each advanced BullMQ pattern, building on basic queue testing to handle the complex orchestration scenarios
