Explain the prototyping approaches in software process.
Two approaches
i. Evolutionary prototyping - In this approach of system development, the initial prototype is prepared and it is then refined by number of stages to final stage.
ii. Throw-away prototyping - Using this approach a rough practical executionof the system is produced. The requirement problems can be identified from this execution. It is then discarded. System is then developed using some disimilar engineering paradigm.
Data validity is the reasonableness and correctness of data.
What are the Problems of Prototyping In some organisations, theprototyping isn't as successful as anticipated. A common problem with this approach is that people expect much
The terms "test scenario" and "test case" are certain used synonymously. Test scenarios are test cases or test scripts, and the series in which they are to be implemented. Test sce

Throw-away prototyping Objective: The principal objective of this model is to validate or to derive the system requirements. It is developed to reduce requir
Sanity testing : - Sanity testing is used to make sure that multiple or conflicting functions or variables do not exist in the system. - It verifies that the components of th
What are the demerits of spiral model? i. It is depends on customer communication. If the communication is not suitable then the software product that gets developed will not r
Test Case A test case is a unit level document describing the inputs, steps of implementation and the expected result of each test condition for each requirement from the BRD.
What is equivalence partitioning? Equivalence partitioning is a black box method that separates the input domain into classes of data. From this data test cases can be derived.
What is Coupling? Coupling is the measure of interconnection among modules in a program structure. It depends on the interface complexity among modules.
