Yes sakshi,Dynamic testing is Functional where we test the application with different inputs and test whether the ouptputs are correct with respect to Inputs.go through these links ---http://en.wikipedia.org/wiki/V-Model ----http://en.wikipedia.org/wiki/Spiral_model ----http://en.wikipedia.org/wiki/Waterfall_model

RE: Difference between static and dynamic testing?

Hi Sakshi Static Testing (also known as Dry Run Testing ) is a form of software testing where the software isn't actually used. Syntax checking and manually reading the code to find errors are methods of static testing. This type of testing is mostly used by the developer himself/herself (who designed or code the module). Static testing is usually the first type of testing done on any system. Dynamic testing is nothing but the the testing of the dynamic behaviour of code. That is dynamic analysis refers to the examination of the physical response from the system to variables that change with time and are not consistent.Some of the Dynamic Testing methodologies include Unit Tests Integration Tests System Tests and Acceptance Tests.

1: Static testing is about prevention dynamic testing is about cure.

2: The static tools offer greater marginal benefits.

3: Static testing is many times more cost-effective than dynamic testing.

4: Static testing beats dynamic testing by a wide margin.

5: Static testing is more effective!

6: Static testing gives you comprehensive diagnostics for your code.

7: Static testing achieves 100 statement coverage in a relatively short time while dynamic testing often often achieves less than 50 statement coverage because dynamic testing finds bugs only in parts of the code that are actually executed.

8: Dynamic testing usually takes longer than static testing. Dynamic testing may involve running several test cases each of which may take longer than compilation.

9: Dynamic testing finds fewer bugs than static testing.

10: Static testing can be done before compilation while dynamic testing can take place only after compilation and linking.

11: Static testing can find all of the followings that dynamic testing cannot find: syntax errors code that is hard to maintain code that is hard to test code that does not conform to coding standards and ANSI violations.

Ya Dynamic testing invoves functional testing also.

Spiral Model:

The spiral model is a software developement process combining elements of both design and prototyping-in-stages in an effort to combine advantages oftop down and botton up concepts. Also known as the spiral lifecycle model it is a systems development method (SDM) used in(IT). This model of development combines the features of the prototyping model and the water fall model. The spiral model is intended for large expensive and complicated projects

Diffrence between Spiral Model V Model and waterfall Model:

Spiral Model/V-Model are for large or complaicated projects.
In Spiral model / V-Model we are conducting cerification and validation at a time.
In waterfall model the validation will takes only at the last stage of before releasing a project.
