They used the "Proxy Learning" mode. They pointed 6.0 between the new Java app and the mainframe. The tool automatically learned request/response pairs, identified stateful patterns (session IDs), and generated virtual services for 200+ transactions in 48 hours .
They manually recorded 50 transactions. The process took 3 weeks. Every time the mainframe changed, they had to re-record.
was solid. It offered protocol support (HTTP, JMS, JDBC, TCP) and a decent Eclipse plugin. However, it suffered from three common enterprise problems: clunky CI/CD integration, a steep learning curve for "composite" scenarios, and latency under high load.
How the latest update closes the gap between development, QA, and DevOps. Introduction: The "Shift-Left" Dilemma For the last decade, the software industry has been obsessed with "shifting left"—catching bugs earlier in the development lifecycle. But there is a persistent roadblock: dependencies.
