All of the Performance Test products include the following functions:

• Record: Captures user sessions on a keystroke-by-keystroke or message-by-message basis. This is accomplished through a global record function for ALL components and interactively in the case of 3270 applications.
• Playback: Re-executes previously recorded sessions either online in interactive or non-stop mode, or in a batch job.
• Comparison: Compares the output of the current playback session with the recorded session.

Each of the components also has specific capabilities to aid testing in their respective environments. For advanced testing, Performance Test incorporates IBM's REXX script language, allowing you to customize and enhance script creation, playback, and reporting.
