Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.
- 1. What is Multiple-inheritance? Explain with an example.
Answer:Multiple inheritance is a feature of some object-oriented computer programming languages in which an object or class can inherit characteristics and features from more than one parent object or parent class.
Multiple inheritance refers to a feature of some object-oriented programming languages in which a class can inherit behaviors and features from more
- 2. What is incremental testing? Explain the ways used to perform incremental testing.
Answer:Incremental testing is a way of integration testing in which first you test each module of the software individually then continue testing by adding another module to it then another.
Its proper explanation is “An integration testing strategy in which you test subsystems in isolation, and then continue testing as you integrate more and more subsystems”.
Incremental testing is partial testing of a sketchy product. The objective of incremental testing is to provide an earlier feedback to software developers.
- 3. List and explain the four phases of the object modeling technique
Answer: The object-modeling technique (OMT) is an object modeling approach for software modeling and designing. It was developed around 1991 by Rumbaugh, Blaha, Premerlani, Eddy and Lorensen as a method to develop object-oriented systems and to support object-oriented programming.
Four phases of the object modeling technique:
- Analysis: The analysis phase starts with a problem statement, and its purpose is to develop the initial problem statement by providing a list of requirements for developers, managers and users. The initial problem statement is
- 4.Explain the different states of activity diagram.
Answer: Activity diagrams are often used to model business processes. They simply and quite plainly show how things work, and so function as a good aid to discussions of aspects of the workflow with the domain experts. These are less abstract than the often used object-oriented state machine diagrams. Activity diagrams are an essential part of the modeling process. They are used to clarify complicated use cases, illustrate control among objects, or to show the logic of an algorithm. The UML 2.0 metamodel substantially refined and improved Activity diagrams; whereas the UML 1.4 Activity diagram was a subclass of State Machine,
- 5. What are the activities in the object oriented design process using unified approach?
Answer:Object-oriented analysis and design (OOAD) is a popular technical approach to analyzing, designing an application, system, or business by applying the object-oriented paradigm and visual modeling throughout the development life cycles to foster better stakeholder communication and product quality.
According to the popular guide Unified Process, OOAD in modern software engineering is best conducted in an iterative and incremental way. Iteration by iteration, the outputs of OOAD activities, analysis models for OOA and design models for OOD
- 6. What are the rules for developing usability testing?
Answer:Usability testing is a technique used in user-centered interaction design to evaluate a product by testing it on users. This can be seen as an irreplaceable usability practice, since it gives direct input on how real users use the system. This is in contrast with usability inspection methods where experts use different methods to evaluate a user interface without involving users. Usability testing focuses on measuring a human-made product’s capacity to meet its intended purpose.
