"We have migrated our department off CA Lisa to reduce our operational costs in performance and system testing environments. We used WireMock for HTTP stubbing and mocking and Traffic Parrot for IBM MQ. Neither WireMock nor Traffic Parrot provides all the features available in CA Lisa. Still, after initial proof of concept assessment, we have decided those tools feature sets will be sufficient for our needs and significantly cut costs. It took our team six months to migrate HTTP to WireMock and another three months working closely with the Traffic Parrot team to improve their offering to meet our load testing and mainframe integration requirements. With this investment, we cut our tooling costs in half."
