In this episode, we discuss integration testing event-driven systems and explore AWS's new Integration Application Test Kit (IATK). We cover the challenges of testing events and common approaches like logging, end-to-end testing, and using temporary queues. We then introduce IATK, walk through how to use it for EventBridge testing, and share our experience trying out the X-Ray trace validation. We found IATK promising but still rough around the edges, though overall a useful addition to help test complex event flows. 💰 SPONSORS 💰 AWS Bites is brought to you by fourTheorem, an Advanced AWS Partner.
