Product Overview

VersaTest VTERM's architecture is designed for scalable and reliable 3270 application testing. The core components include the Test Engine, which executes test scripts; the Communication Handler, responsible for managing TN3270 and TN3270E connections; the Script Interpreter, which parses and executes test scripts written using commands like `CONNECT`, `SEND`, `RECEIVE`, and `VERIFY`; and the Reporting Module, which generates detailed test reports. Communication between components is primarily through TCP/IP.

Configuration is managed using YAML files, typically stored in `/opt/verstatest/config`. The system exposes a REST API with endpoints such as `/api/v1/sessions`, `/api/v1/scripts`, and `/api/v1/results`, facilitating integration with CI/CD pipelines. 509 certificate authentication, with RBAC for access control.

Competing products like IBM Rational Functional Tester and Micro Focus UFT offer similar features, but VersaTest VTERM's modern API-centric design and focus on security provide a distinct advantage.

Frequently Asked Questions

What is VersaTest VTERM and what does it do?

VersaTest VTERM is designed to extend testing capabilities to 3270 applications, allowing users to perform automated testing, data validation, and performance monitoring of mainframe applications through a standard interface. It supports scripting and integration with other testing tools.

What protocols does VersaTest VTERM use for communication?

VersaTest VTERM supports multiple 3270 emulation protocols, including TN3270 and TN3270E. It also supports SSL/TLS for secure communication with mainframe systems. The communication relies on standard TCP/IP connections.

How are test cases defined and executed in VersaTest VTERM?

VersaTest VTERM uses a scripting language for defining test cases. Scripts can include commands to interact with the 3270 application, such as 'SEND', 'RECEIVE', and 'WAIT'. Data validation is performed using regular expressions and data masks.

How does VersaTest VTERM integrate with other testing tools?
