A manual operation replay unit replays messages generated by manual operations among the messages sent to the current host system by the terminal. An automatic response unit automatically generates a response message for messages received from the new host system. The automatic response unit also generates screen data for a screen displayed on the terminal on the basis of messages received from the new host system. A comparison unit compares and evaluates screen data generated by the automatic response unit and screen data from a screen generated by the terminal on the basis of messages received from the current host system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device, method and program for performing system testing","description":"In an approach for testing the operations of a host system during a host system migration, a terminal agent exchanges messages already exchanged between the current host system and a terminal with the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9720791","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
