Data Driven and Containerized Testing of Multi Service Networked Systems
summary
Demo shows a concrete toolchain that composes modular Docker Compose modules, runs full-service stacks on one host, injects layer 2 and 3 network topology and impairments, and runs generative tests against a simple oracle to find divergences. Tools used are conlink for bridges, switches, DHCP and packet loss/latency, dcmon for log and health checks, and instacheck plus dctest to generate, shrink and replay failing HTTP sequences; the system finds and shrinks real divergences and the demos run end to end.
