Q

What is the difference between breakpoints and watchpoints?

To ensure the program is robust
To ensure the program is reliable

21
Q

What are the three types of test data?

A

Normal, Extreme, Exceptional

22
Q

Apart from Analysis, state two other parts of the waterfall method where the Software Specification is used

A

Design - guidance to ensure that what the programmers are coding meets the specification
Testing - to ensure that the software produces the right output and does everything required

23
Q

Describe ‘Comprehensive’ testing

A

Comprehensive - tests every possible scenario

24
Q

What are the three types of errors?

A

Syntax
Logic
Execution (Run-time)

25
Q

What are the three stages in Alpha Testing?

A

Component
Module
System

26
Q

Describe an advantage of Beta Testing

A
  • will test more thoroughly as not biased towards code, so will try to break it more than the programmer will do
27
Q

What are the three types of testing?

A

Alpha
Beta
Acceptance

28
Q

In Acceptance testing, where should it be carried out and what should the user get?

A

It should be carried out in the location of use (client use)

They should get full unrestricted access to system

29
Q

Describe the ‘Documentation’ phase

A

Documentation is where the programmer formally writes up documents about software

30
Q

What three essential pieces of software should be produced in the documentation phase?

A

User guide
Technical guide
EULA

31
Q

What is EULA?

A

A legally binding document that states the copyright regulations of the software

32
Q

In what guide from the documentation phase would you expect to find the typical system requirements?

A

Technical Guide

33
Q

What are the three types of maintenance?

A

Corrective
Adaptive
Perfective

34
Q

Describe the difference between adaptive and perfective maintenance

A

Adaptive is changing the software to adapt to a new environment
Perfective is changing the software to add new features that the user has requested

35
Q

What are the factors that affect maintenance?

A 
Staff Mobility(Whether the original programmers are still with company)
Amount of Documentation
36
Q

What is the main question asked in the evaluation phase?

A

Does the software meet software specification?

37
Q

What are the list of criteria for the evaluation phase?

A 
F it for purpose 
R eliability 
R obustness 
E fficiency 
U ser interface
R eadability 
P ortability
38
Q

Define what is meant by software that is ‘Robust’

A

It is able to cope with unexpected input(outside normal range) without crashing

39
Q

What describes a good user interface?

A
  • Consistent
  • Customisable
  • Accessible for all
40
Q

Define Portability of software

A

Portability of software is how adaptable it is to running on other systems that the one it was designed for with little or no change

41
Q

Define what is meant by <em>‘Software development is an iterative process’</em>

A

An iterative process is one in which stages of the process may have to be repeated
Software development is an iterative process because many steps may have to be repeated in order to refine the end product

42
Q

Who would be responsible for producing the project timescale plan?

A

Project Manager

43
Q

Describe what happens in the ‘Rapid Application Development’ Methodology

A

RAD involves building lots of prototypes and refining those prototypes until an end product is reached

44
Q

Describe two advantages of the RAD methodology

A
  • Users are much more involved, and are involved in all stages allowing to comment on and refine the design
  • Shorter development time
  • Able to change design at multiple points
45
Q

If a company was looking at designing a website what design methodology would you recommend and why?

A

Agile because

  • flexible
  • suited to small projects and web design
46
Q

Describe two advantages of agile

A
  • Increased responsiveness

- Reduced costs due to smaller groups of developers

47
Q

Describe a disadvantage of agile

A
  • Too extreme

- Encourages change to software specification

48
Q

What are the three types of test data?

A

Normal
Extreme
Expectional

49
Q

What is the cost of developing a new system?

A

Hardware

Developing Software

50
Q

What does fit for purpose mean in relation to software evaluation?

A

It does required job and does what it is meant to do
