Anybody please answer this question...I am very much confused!!!

testing methodology is nothing but the way we are testing 
like white box, gray box and black box.

and testing techinques are those which we use to prepare 
test cases like equivalence class partitioning, boundary 
value analysis, cause-effect graphing and error guesing.

pls tell me if i am wrong

You're right with the techniques, I just will add the All-
Pairs algorithm to have the basics, but this one is less 
used.

About the methodology, this is how you will execute your 
testing process, maybe using a V model or Extreme Testing, 
or RUP or any other.

What you describe in methodology are more testing types, 
and it also include system testing, performance, unit, etc 
etc etc.

I have read a lot of testing authors, and may of them 
disagree between techniques, methodologies or testing 
types. Right now, there is not any information source to 
align all the testng concepts..

Test Methodology":
testing methodology is a document prepared by the project 
manager(PM).this document consists os the scope and budjet 
allocation of the project.and testers detailes and their 
responsibilities .and also about automations,and defect 
reporting and tarcking ,risks and assumptions like details 
about that project.
Testing Techniques:
testing techniques are white box and black box testing 
techniques.as a tester we will perform mostly blacbox 
testing techniques.i.e boundary value analysis
(BVA).equalance class partitioning(ECP),Decision 
tables,state transition diagrams

pls tell me if its wrong

I think u r totally wrong jyothinapa

Test Methodology is a 3 step process:
1. Creating Test Strategy
2. Creating Test Plan/Design
3. Execution of Test Cases.

Test Technique is way we use to prepare 
test cases:
1.Like equivalence class partitioning
2.boundary value analysis
3.cause-effect graphing 
4.error guesing.

Actually , I dont know.
