lecture 8

Question 1

testing

Answer 1

the process of examining a component, subsystem, or system to determine its operational characteristics and whether it contains any defects

Question 2

test case

Answer 2

a formal description which contains the starting state, then the system goes through different events in which the response to each event should match the predicted responses or ending state

Question 3

characteristics of a test case

Answer 3

• it is defined based on functional and non-functional requirements
• must test all normal and exception situations

Question 4

test data

Answer 4

a set of starting states and events that are used to a test a module, group of modules or system

Question 5

unit test

Answer 5

testing of an individual method, class, or component before integrating it with other softwares

Question 6

integration test

Answer 6

testing of a group of methods, classes or components to see how they behave together

Question 7

usability test

Answer 7

testing to determine whether a method, class, subsystem, or system meets user requirements

Question 8

why is usability testing required

Answer 8

because the test involves functional and non-functional requirements

Question 9

how are functional requirements evaluated

Answer 9

use case by use case

Question 10

system test

Answer 10

an integration test of the entire system or subsystem

Question 11

characteristics of system testing

Answer 11

• it is preformed regularly

- can be performed after each iteration

Question 12

build and smoke test

Answer 12

a system test that is performed daily or several times a week

Question 13

performance/stress test

Answer 13

a type of integration and usability test that determines whether the system or subsystem can meet the time-based performance criteria

Question 14

response time

Answer 14

the desired or maximum allowable time limit for software response to a query or update

Question 15

throughput

Answer 15

the desired or minimum number of queries and transactions that must be processed per a certain period of time

Question 16

user-acceptance test

Answer 16

a system test performed to determine if the system fulfills the users’ requirements

Question 17

characteristics of user-acceptance testing

Answer 17

• can be performed in the final stage
• can be performed after each iteration
• it is a formal activity
• payments to the system are tied to passing this test
• details of the tests can be included in the request for proposal (RFP) and procurement contract

Question 18

what does an operational system require

Answer 18

a fully populated database to support ongoing processing

Question 19

data needed at system startup can be obtained from:

Answer 19

• files or databases of a system being replaced
• manual records
• files or databases from other systems in the organization
• user feedback during normal system operation

Question 20

training is needed for..

Answer 20

end users and system operators

Question 21

training for end users must..

Answer 21

emphasize on hands-on use for specific business processes and functions

Question 22

example of hands-on use

Answer 22

• accounting
• inventory control
• order entry

Question 23

system operator training

Answer 23

it is a less formal training approach where computer operators and administrators can learn all they need to know via self-study

Question 24

Source code control system (SCCS)

Answer 24

is an automated tool for tracking source code files and controlling changes to those files

Question 25

what does SCCS allow for

Answer 25

one programmer at a time to check out the file (code) in read/write mode

Question 26

what is read-only mode used for

Answer 26

when a programmer wants to check out the file without causing any changes

Question 27

3 different approaches of deployment

Answer 27

• direct deployment
• parallel deployment
• phased deployment

Question 28

direct deployment

Answer 28

a deployment method that installs a new system, quickly makes it operational, and immediately turns off any overlapping systems

Question 29

risk and cost of direct deployment

Answer 29

higher risk, lower cost

Question 30

parallel deployment

Answer 30

a deployment method that operates the old and the new systems for an extended time period

Question 31

risk and cost of parallel deployment

Answer 31

lower risk, higher cost

Question 32

phased deployment

Answer 32

• a deployment method that installs a new system and makes it operational in a series of steps or phases
• each phase, adds components and functions to the operational system
• also in each phase, the system is tested

Question 33

to submit error reports and change requests…

Answer 33

• use standardized reporting methods
• requests should be reviewed by project managers
• change control committee

Question 34

to implement change…

Answer 34

• identify what parts of the system must be changed
• secure resources to implement the change
• schedule design and implementation activities
• develop a test criteria and testing plan for the changed system

Question 35

alpha version

Answer 35

a test version that is incomplete but ready for some level of rigorous integration or usability testing

Question 36

beta version

Answer 36

a test version that is stable enough to be tested by end users over an extended period of time

Question 37

production version/release

Answer 37

a system version that is formally distributed to users or made operational for long-term use

Question 38

maintenance release

Answer 38

a system update that provides bug fixes and small changes to existing features

Question 39

the multiple versions are used to…

Answer 39

handle the complexity associated with testing and supporting a system
