Module Two

Question 1

What is the software development life cycle model

Answer 1

Describes the types of activity performed at each stage in a software development project and how the activities relate to one another logically and chronologically

Question 2

What are the 4 lifecycle modal characteristics of good testing

Answer 2

1) For each development activity there is a corresponding testing activity
2) Each test level has test objectives specific to that level
3) The analysis and design of tests should begin during the corresponding development activity
4) Tester participate in discussions to define and refine requirements and design and are involved in reviewing work products as soon as drafts are available

Question 3

What is a Sequential Development Model

Answer 3

Describes the software development process as a linear, sequential flow of activities

Question 4

What is incremental Development model

Answer 4

Involves establishing requirements, designing, building and testing a system in pieces which means that the software features grow incremental

Question 5

What is Iterative Development Model

Answer 5

Occurs when groups of features are specified, designed, built and tested together n a series of systems often of a fixed duration.

Question 6

What is Component testing

Answer 6

Focuses on components that are seperaetly testable

Question 7

What is the component testing test objective

Answer 7

The objectives are

1) to reduce risk
2) verifying the functional and non-functional behaviors of a component
3) Building confidence in a component quality
4) finding defects in the component
5) preventing defects from escaping to higher test levels

Question 8

what is the component testing test basis

Answer 8

Examples of work products that can be used as a test basis includes
Detailed design
code
data model
component specifications

Question 9

What are component testing test objects

Answer 9

Includes
Components, units or modules
code of data structures
classes
database modules

Question 10

What are component testing - test defects and failures

Answer 10

includes
incorrect functionality
data flow problems
incorrect code or logic

Question 11

What is Integration Testing

Answer 11

Focuses on interactions between components or systems

Question 12

What are the objectives of integration testing

Answer 12

The objectives are

1) to reduce risk
2) verifying the functional and non-functional behaviors of a component
3) Building confidence in the quality of the interfaces
4) finding defects in the component
5) preventing defects from escaping to higher test levels

Question 13

What are the test basis of integration testing

Answer 13

Software and system design
Sequence diagrams
interface and communication protocol
use cases
workflows

Question 14

What are the test objects of integration testing

Answer 14

Sub systems
databases
infrastructure
interfaces
APIs
microservices

Question 15

Test defects and failures of integration testing

Answer 15

includes
incorrect data or missing data
incorrect sequencing
interface mismatch

Question 16

What is system testing and what are the test objectives

Answer 16

focuses on behaviour and capabilities of a while system or product, considering the end to end tasks the system can perform and the non-functional behaviours it exhibits while performing those tasks

Question 17

What is system testing - test objectives

Answer 17

The objectives are

1) to reduce risk
2) verifying the functional and non-functional behaviors of a component
3) Building confidence in the quality of the system as a whole
4) finding defects
5) preventing defects from escaping to higher test levels

Question 18

What are the 4 Acceptance testing types

Answer 18

1) user acceptance testing
2) operational acceptance testing
3) contract and regulation acceptance testing
4) alpha and beta testing.

Question 19

What is functional testing

Answer 19

involves tests that evaluate functions that the system should perform. Should be performed at all test levels though the focus is different at each level

Question 20

What is non-funcational

Answer 20

Describes the tests required to measure characteristics of systems and software that can be quantified on a varying scale. Performed at all test levels.

Question 21

What is white box testing

Answer 21

Derives tests based on the systems internal structure or implementation. Internal structure may include code, architecture, work flows and/or data flows within the system

Question 22

What is maintenance testing

Answer 22

Once deployed to production environments, software and system need to be maintained. examples of changes can be

1) to fix defects discovered in operational use
2) to add new functionality
3) to delete or alter already-delivered functionality

Question 23

What is the maintenance testing scope

Answer 23

The degree of risk of the change for example the degree to which the changed area of the software communicates with other components or systems.

Question 24

What are the 3 maintenance testing triggers

Answer 24

1) Modification - Planned enhancement
2) Migration - from one platform to another
3) Retirement - application reaches end of its life

Question 25

What is the maintenance testing impact analysis

Answer 25

It evaluates the changes that were made for a maintenance release.
