Bullet point WHY ?

Reduce Mainframe Dependency & Faster Troubleshooting:

Development and support teams can reproduce issues without requiring direct access to customer mainframe systems.

When a user encounters an issue:

  1. the scenario is recorded using TrafficPlayer,
  2. support teams replay the exact same sequence,
  3. investigations become faster and fully reproducible.

Use Case: Non-Regression Testing

TrafficPlayer provides a reliable framework for functional regression validation:

  • record a reference business workflow,
  • replay it automatically after software changes,
  • verify that application behavior remains unchanged.

This enables teams to:

  • industrialize mainframe testing,
  • secure software deliveries,
  • quickly detect functional regressions.

Bullet point WHAT ?

TrafficPlayer is a Telnet traffic recording and replay solution designed for mainframe environments.

It captures real user interactions on a terminal session and replays them identically without requiring access to the original mainframe system.

The solution is built around two main capabilities:

  • Traffic recording — capturing user/mainframe interactions.
  • Scenario replay — simulating recorded exchanges through a Telnet proxy.

Thanks to its modular Maven-based architecture, TrafficPlayer can be integrated into Java IDEs such as Cobos4i.

Bullet point HOW ?

TrafficPlayer acts as an intermediary between the terminal emulator and the mainframe.

TrafficPlayer capture user interactions:

  • screens received from the host,
  • user actions,
  • Telnet network exchanges.

Recorded scenarios are stored in files containing configuration and captured traffic

Captured sessions can then be replayed:

  • without connecting to the real mainframe,
  • inside development or testing environments,
  • directly from the integrated IDE.

Integration into Cobos4i

Two integration approaches are possible:

  • reuse the scortplayerrecorder core module and develop a dedicated UI,
  • adapt the esed_trafficplayer graphical module by removing Enterprise Studio dependencies.
