hai this is sunithayagnamurthy

testing methodology's:
                        1.block box testing
                        2.white box testing
                        3.grey box testing
 It is also include unit testing 
                    integration testing
                    sandwich testing
                    bit-band testing etc
                    

block box testing: this test is conducted by test engineer
it test only functionality of the application as per the
customer requirement.
white box testing:  this test is conducted by white box test
engineer or developer.it test the code is working or not.
 Every white box test engineer should have programing skills
grey box testing: it is integrated block box testing & white
box testing
Unit testing : this testing is conducted by white box test
engineer or developer.it should have programing skills
1)to test single peace of code or module in a project
integration testing: this test conducted testing engineer.it
test integrated two or modules at a time.
they are three or more types
1)top-down approach
2)bottom up approach
3)sandwich testing
top-down approach:
                   it test main module to submodule.due to
some reasons the main module till not developed temporary
module is created that module name called stub.
bottom-up approach:
                   it test submodule to main module.due to
some reasons the main module is not developed the temporary
module is created .it called as driver.It acts as main module.
sandwich approach: both top down & bottom up approach called 
sanwich approach
system testing also included in  testing methodologies
system testing:
               system testing it is like block box testing 
it test the functional requirement working or not as per the
customer requirement. This is called system testing.

sanatory test:sanatory test means it is like positive
testing.it test the functionality is working or not as per
the customer requirment

 This is the testing methodologies & sanatory testing.
      

all the best of ur interview


If any mistakes is their please excuse

ok keep smiling 
Byeeeeeeeeeeeeeeeeee

Testting Methodology:-

Software Testing Mothodology is a three step process of 
1)- Creating Test Test Plan\ Test Strategies
2)- Designing\Developing Test Cases AND
3)- Executing Test Cases & Reporting appropriate Bugs.

Test Strategy can be defined as a road map which is 
followed during entire testing process.It varies from 
company to company. It includes steps from studying 
specification documents to closing a bug.

Correct me if  I am wrong.
