.

2. . Several techniques of Requirements discovery are covered in this book. Which one is not the case? a

a)Model-driven engineering

b)Scenarios

c)Interviewing

d)Ethnography

Part 2 Mark the right statement √, the wrong statement×(1*15=15)

1.In the software architecture design,using large-grain components improves

performance and maintainability.

2.According Lehman and Belady's ‘laws’ , A program that is used in a real-world

environment must necessarily change, or else become progressively less useful in

that environment.

Part 3 Fill the blankets: (1*15=15)

1.the attributes of good software are are Maintainability , Dependability,

Efficiency , Acceptability

2.General issues that affect most software are heterogeneity , Business and social change ,

Security and trust .

3.The reasons of software change are 1 New requirements emerge when the software is

used ,The business environment changes ,Errors must be repaired ,New

computers and equipment is added to the system;

The performance or reliability of the system may have to be improved.

4.Generic process models are The waterfall model , Incremental development ,

Reuse-oriented software engineering.

5. A structured set of activities required to develop a software system, which are

Specification , Design and implementation, Validation _, Evolution.

Part 4 Answer the following questions in brief. (4*5=20 )

1.What are the program testing goals?

Program testing goals

To demonstrate to the developer and the customer that the software meets its requirements.

For custom software, this means that there should be at least one test for every

requirement in the requirements document.

For generic software products, it means that there should be tests for all of the system

features,

plus combinations of these features, that will be incorporated in the product release.

To discover situations in which the behavior of the software is incorrect, undesirable or does not conform to its specification.

Defect testing is concerned with rooting out undesirable system behavior such as system crashes, unwanted interactions with other systems, incorrect computations and data corruption.

2.What is architectural patterns?

Architectural patterns are a means of reusing knowledge about generic system architectures. They describe the architecture,

explain when it may be used and describe its advantages and disadvantages.

3.What is the difference between software engineering and computer science?

Computer science is concerned with theory and fundamentals; software engineering is

concerned with the practicalities of developing and delivering useful software

4.What differences has the web made to software engineering?

The web has led to the availability of software services and the possibility of developing highly distributed service-based systems.

Web-based systems development has led to important advances in programming languages and software reuse.

5.What is Software architecture design?

Software architecture design

The design process for identifying the sub-systems making up a system and the framework for sub-system control and communication is architectural design

The output of this design process is a description of the software architecture

The architecture of a packing robot control system

6.What is Path testing？

The objective of path testing is to ensure that the set of test cases is such that each path through the program is executed at least once

Binary search flow graph

Part 5 Solve the following problems(30)

1.(5) Based on your experience with a bank A TM, draw an activity diagram that models

the data processing involved when a customer withdraws cash from the machine.

2.(5) Develop a sequence diagram showing the interactions involved in a application.

3.(5) Design the application architecture using the MVC pattern.

4.(5)Design a set of test data to accomplish the path testing about the following program

(Figure 1).

5.(10) Based on the statechart which models a application, describe the whole process in

detail.
