This section explains how to develop load test scripts for applications that use legacy or custom TCP/IP based protocols. It explores the challenges that are commonly encountered in this type of testing: dealing with dynamic server responses, translating between character code tables, string manipulation of binary data, and more.
Three protocols are examined in detail: Telnet, TN3270e, and a custom TCP/IP based protocol. Using recorded scripts from actual load test projects as examples, you will be guided through the process of recording an application, analyzing traffic, configuring recording rules, and customizing a script.
