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

Inngest Function Testing: Step Mocking, Event Dispatch, and Retry Logic

Inngest is a serverless background job platform that runs durable functions via event triggers. Unlike traditional job queues, Inngest functions are composable: each step.run is a discrete, retriable unit. Testing this architecture requires understanding how Inngest executes functions and where your logic actually lives. How Inngest Executes Functions Inngest
