Load Testing & Monitoring Adobe Flex Applications

You use Adobe Flex!

See also:

Flex®, Adobe®’s development solution for rich Internet applications (RIA’s), is an open source framework for creating highly interactive and intuitive applications that deploy in an identical manner on most browsers, workstations and operating systems. To communicate between the client workstation and the server, Flex relies on a protocol called AMF (Action script Messaging Format).

Neotys is Ready!

Thanks to Neotys, you can create scenarios to test and monitor your Flex applications‘ behavior under stress and validate their performance while pinpointing any weaknesses. Realistically testing and monitoring your applications with NeoLoad and NeoSense means you can deliver better performance to your customers at a lower total cost of ownership.

Flex Support

Since the Flex technology is based on a binary protocol, testing and monitoring Flex applications requires this protocol to be specifically supported. Neotys’ Flex capabilities allow you to: Record the AMF traffic to be played back (module not required for text or XML traffic). Extract/replace AMF data during the test in order to variabilize the calls (the data is presented in XML format in the scenario). Automatically handle the session IDs used by AMF. Handle streaming channels (Push support required).


Certain Flex or Air applications may use the RTMP protocol as the transport layer. See NeoLoad’s RTMP support.
