That depends on the model which you are following...


If you are following Waterfall Model, testing comes after
development i.e. 
Analysis-->Design-->coding-->Testing-->Maintenance


If you are following V-Model, testing comes in every phase.
i.e. Verification and Validation of each phase.

In V model testing comes in every phase. you have not 
specified any model.

In general process QA/QM involves in initial phase .

we can't specify the any model. if all companies are 
followed by the V-model.

see, testing people involved in design phasemtester 
willdesign testcases at the time

actually it depends on SDLC models
some times developing and testing starts parelly
some times after coding is done

Hi Usha,,,

Here it goes..

There are two tpyes of testing which one you are refering.
1) Conventional testing
2) UnConventional testing.

Conventional testing is what testing engineers do in testing
phase any SDLC --> any model..
Unconventional testing is waht QA people do in each & every
phase of SDLC(verification & validation)..

Still doubtfull...plse mail at vsasi3@gmail.com
