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.
What are the aims of testing? i. Testing is a process of executing a program with the target of finding an error. ii. A good test case is one that has high possibilit

What are the merits of incremental model? i. The incremental model can be adopted when there is less number of people included in the project. ii. Technical risks can be man
What does Validation represent? Validation show the set of activities that make sure that the software that has been built is satisfying the customer requirements.
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.
Q. Define capability. What are the quantities that determine the degree of capability of a software reliability model? Ans: Capability demotes to the ability of the model to
When is RTM (Requirement traceability matrix) prepared - after or before test case designing? - RTM is prepared before test case designing. - Requirements must be traceable
