Test methodology depends on how application is tested what 
part of application is tested and whom the application is 
tested .
 there are 2 typs of testing 
1.Black box testing
2.White box testing

hi vidya,
black box testing in done in testing phase and white box 
testing has to be performed in coding phase in all the 
applications.so they  are types of testing..

methodology means what model suites ur application ie.
waterfall model,spiral model,V model and so on....

Testing methodology is nothing but what kinds of methods to 
be selected that suits for our application. it deals not 
only the type of SDLC but also Testing techniques

suppose Test strategy says 2o types of Testing techniques 
whereas Test methodology say what testing techniques to be 
applied that fits for application it may be 20 or less than 
20 testing techniques .it's purely application dependent


Hi guys Correct me if Iam Wrong

Testing methodology is the approach you are using for 
testing.
As said above, different models are used for this purpose:
- Waterfall model
- V Model
- Spiral Model
- Incremental Engineering
- Evolutionary Model
and many more

Our software testing methodology is applied in three 
distinct phases: unit testing, system testing, and 
acceptance testing. 

Unit Testing::::—The programmers conduct unit testing 
during the development phase. Programmers can test their 
specific functionality individually or with other units. 
However, unit testing is designed to test small pieces of 
functionality rather than the system as a whole. This 
allows the programmers to conduct the first round of 
testing to eliminate bugs before they reach the testing 
staff. 
System Testing::::—The system is tested as a complete, 
integrated system. System testing first occurs in the 
development environment but eventually is conducted in the 
production environment. Dedicated testers, project 
managers, or other key project staff perform system 
testing. Functionality and performance testing are designed 
to catch bugs in the system, unexpected results, or other 
ways in which the system does not meet the stated 
requirements. The testers create detailed scenarios to test 
the strength and limits of the system, trying to break it 
if possible. Editorial reviews not only correct 
typographical and grammatical errors, but also improve the 
system’s overall usability by ensuring that on-screen 
language is clear and helpful to users. Accessibility 
reviews ensure that the system is accessible to users with 
disabilities. 
Acceptance Testing::::—The software is assessed against the 
requirements defined in the system requirements document. 
The user or client conducts the testing in the production 
environment. Successful acceptance testing is required 
before client approval can be received.

It means what type of testing we will applied for that 
application.
eg:unit,system.......ect testing.

Testing methodology is nothing but in how methods we should
test the application..Normally we test the application in
two methods..1.blockbox testing is for functional part
          2.whitebox testing is for structural part.

In general,the system testing process is starting with
system test initiation by PROJECT MANAGER/TEST MANAGER. The
corresponding PM/TM is preparing TEST STRATEGY (OR) TEST
METHODOLOGY.This document defines an approach to be followed
by testing team in current project.

Methodology means the method we follow at our organization 
like v-model, spiral, waterfall etc.....
