WebSocket support for JMX generation

[davidcampbelldc]

Summary

Add WebSocket protocol support for JMX script generation in LoadMagic.

Background

From Testing Mavens partnership meeting (Feb 16, 2026):

• Testing Mavens uses WebSockets for a couple of chat-based applications, tested via JMeter.
• Alex and team figured out how to use JMeter for WebSockets, which is challenging.
• Jayan suggested future demand for WebSocket support may increase due to AI applications using WebSocket connections.
• David agreed to park this as a low/medium priority unless it can be implemented as a quick win.

Decision Status

SHELVED — Low priority. Revisit in a future phase or if it can be done as a quick win. Current project load does not justify prioritizing this.

Acceptance Criteria

• LoadMagic can generate JMX scripts that include WebSocket samplers
• WebSocket request/response correlation is supported
• Compatible with JMeter WebSocket plugin(s)
