Will you clarify your question.I mean to say I am not getting your question.

"Either you are willing to know what are different testing experts available, or different designation of tester as per experience?"

From what I understand.....................

Manual Testers,
Unit Testers,
Automation Testers,
Performance Testers,
Load Testers,
Functionality Testers,
Database Testers,
Web-based Testers,
Application s/w based testers etc

This list may go on depending on the project and the process.

Automatiion Testers include both functional and performance ones. So we can clasify it as ...
[B]Functional Automation Tester, &
Performance Tester.[/B]
However, Load & Stress Testing is part of Performance Testing only. So as a whole its only Performance Tester.
Another Classification that I can make is [B]Hardware Testers[/B], who test the Hardwares.
