Which software Test Model Is Best to use???

Which SoftwareTest Model is Best to implement?Today 'V' model is used in many comapnies...what are the advantages and disadvantages of this model as compare to other model??

I am providing some information related to your query. Kindly go through it and let me know if u need further help in this regard.

A test model should:

1. force a testing reaction to every code handoff in the project.
2. require the test planner to take explicit, accountable action in response to dropped handoffs, new handoffs, and changes to the contents of handoffs.
3. explicitly encourage the use of sources of information other than project
documentation during test design.
4. allow the test effort to be degraded by poor or late project documentation, but prevent it from being blocked entirely.
5. allow individual tests to be designed using information combined from various
sources.
6. allow tests to be redesigned as new sources of information appear.
7. include feedback loops so that test design takes into account what’s learned by running tests.
8. allow testers to consider the possible savings of deferring test execution.
9. allow tests of a component to be executed before the component is fully assembled.

The disadvantages are as follows

1. ignores the fact that software is developed in a series of handoffs, where each handoff changes the behavior of the previous handoff,

2. relies on the existence, accuracy, completeness, and timeliness of development documentation,

3. asserts a test is designed from a single document, without being modified by later or earlier documents, or

4. asserts that tests derived from a single document are all executed together.

As Of My Experience and Knowledge "V" Model is Best To Implement
Nandanavanam has given Valueable Details about this

[niranjan123]

yes i agree that V models have many advantages...but when there is a change in plan or change in requiremets....it cannot accomodate this changes effectively.Also as the model specify that component be executed before the component is fully assembled....But if we find a problem when integrating...this componets...our all time and energy loss while doing our single components test..i want to say that why not do this two phase consecutively.......that make the testing more effective.
