[raghunn]

I am aware of Functional testing types and they are:

Unit Testing
Smoke testing / Sanity testing
Integration testing which includes both Top Down and Bottom up Testing
Interface & Usability Testing
System Testing
Regression Testing
Pre User Acceptance Testing which includes Alpha & Beta
User Acceptance Testing
White Box Testing, Black Box Testing
Globalization and Localization Testing

Someone has to guide about Non-functional testing types.

Non-functional testing types are

Load and Performance Testing
Ergonomics Testing
Stress & Volume Testing
Compatibility & Migration Testing
Data Conversion Testing
Security / Penetration Testing
Operational Readiness Testing
Installation Testing
Security Testing

But it would be nice if someone could explain in brief what each of these means as I am aware of only the names.
