Chapter 2 Testing throughout the software development life cycle

Question 1

Sequential development modeld

Answer 1

A type of devlopment life cycle model in which a complete system is developed in a linear way of several discrete and successive phases with no overlap between them.

Question 2

Test level (test stage)

Answer 2

A specific instantiation of a test process.

Question 3

Commercial off-the-shelf (COTS)

Answer 3

A software product that is developed for the general market, i.e. for a large number of customers, and that is delivered mto man customers in identical format.

Question 4

Test objective

Answer 4

A reason or purpose for designing and executing a test.

Question 5

Test basis

Answer 5

The body of knowledge used as the basis for test analysis and design.

Question 6

Test object

Answer 6

The component or system to be tested.

Question 7

Test environment (test bed, test rig)

Answer 7

An environment containing hardware, instrumentation, simulators, software tools and other support elements needed to conduct a test.

Question 8

Component testing (module testing, unit testing)

Answer 8

The testing of individual harware or software components.

Question 9

Integration testing

Answer 9

Testing performed to expose defectgs in the interfaces and in the interactions bewteen integrated components or systems.

Question 10

Component integration testing (link testing)

Answer 10

Tsting performed to expose defects in the interfaces and interactions between integrated components.

Question 11

System integration testing

Answer 11

Testing the combination and interaction of systems.

Question 12

System testing

Answer 12

Testing an integrated system to verify that it meets specified requirements.

Question 13

Acceptance testing

Answer 13

Formal testing with respect ot user needs, requirements, and business processes conducted to determine whether or not a system satisfies the acceptance criteria and to enable the user, customers or other authorized entity to dtermine whether or not to accept the system.

Question 14

User acceptance testing

Answer 14

Acceptance testing conducted in a real or simulated operational environement by intended users focusing on their needs, requirements and business processes.

Question 15

Operation acceptance testing (production acceptance testing)

Answer 15

Operational testing int the acceptance test phase, typically performed in a operation environement by and/or systems administration staff focusing on operational aspects, for example recoverability, resource-behavviour, installability and technical compliance.

Question 16

Contractual acceptance testing

Answer 16

Acceptance testing conducted to verify whether a system satisfies its contractual requirements.

Question 17

Regulatory acceptance testing

Answer 17

Acceptance testing conducted to verify whether a system conforms to relevant laws, policies and regulations.

Question 18

Alpha testing

Answer 18

Simulated or actual operationl teting conducted in the developer’s test envrironment, by roles outside the development organisation.

Question 19

Beta testing (field testing)

Answer 19

Simulated or actula operational testing conducted at an external site, by roles outside the development organisation.

Question 20

Test type

Answer 20

A group of test acivities based on specific test objectives aimed at specific characteristics of a component or system.

Question 21

Functional testing

Answer 21

Testing conducted to evaluate the compliane of a component or system with functional requirements.

Question 22

Non-functional testing

Answer 22

Testing conducted to evaluate the compliance of a component or system with the non-functional requirements.

Question 23

White box testing

Answer 23

Testing based on an analysis of the internal structure-based of the component or system.

Question 24

Conformation testing

Answer 24

Dynamic testing conducted after fixing defects with the objective to confirm that failures caused by those defects do not occur anymore.

Question 25

Regression testing

Answer 25

Testing of a previously tested component or system following modification to ensure that defects have not been introduced or have been uncovered in unchanged areas of the software as a result of the changes made.

Question 26

Maintenance testing

Answer 26

Testing the changes to an operational system or the impact of a changed environment to an operational system.

Question 27

Impact analysis

Answer 27

The identification of all work products afected by a change, including an estimate of the resources needed to accomplish the change.
