what is V Model?
The V-Model splits testing into two parts as Design and Execution. The model starts with overall business requirement.Once the requirement is ready then software,hardware,human resource requirement becomes the next step.Then the detailed design of software will be prepared based on the SRS..This design document will be used as a blue print for the later phases like coding and testing. Test design starts with the time when requirement document (SRS) is ready. Test design is done early while the test execution is done at the end. After design phase, the construction(coding) will be followed based on the system design document and SRS. As the testing design is ready, the execution of testing will be conducted by the tester.There are different types of tests for each phases of this life cycle model. In Execution, program units have to be tested independently before combining them into components. This is called Unit testing. With the individual units of system is tested then units are co
