Testing

Question 1

Types of functional testing

Answer 1

unit
intergration
system
regression
user acceptance

Question 2

types of non functional testing

Answer 2

documentation
installation
performance
reliability
security

Question 3

types of performance testing

Answer 3

load
stress
scalability
volume

Question 4

what is unit testing

Answer 4

testing a unit/compnent of the code

usually the first level of testing done

Question 5

what is integration testing

Answer 5

test how different software modules integrate with each other and makes sure that the functionality remains the same and correct

Question 6

big band approach - integration testing

Answer 6

everything at once

Question 7

incremental integration testing

Answer 7

tested in phases
top down - higher level modules tested first
bottom up - lower level modules tested first
sandwhich approach - test lower and higher level modules together

Question 8

what is regression testing

Answer 8

conducted as we add new features to ensure that the addition of these new features did not break previously developed features

Question 9

seven types of regression testing

Answer 9

corrective 
retest all
selective
progressive
complete
partial
unit

Question 10

corrective regression testing

Answer 10

used when there are no changes introduced in product specs with existing test cases that we can reuse to conduct the test

Question 11

retest all regression testing

Answer 11

tedious and wastes time

testing all aspects of product as well as reusing all the test cases

Question 12

selective regression testing

Answer 12

used to analyze impact of new code

subset of existing test cases is used

Question 13

progressive regression testing

Answer 13

works when there are changes done in the program specs as well as new tests are designed
ensures that no features exist in the previous version that has been compromised by new version

Question 14

complete regression testing

Answer 14

best used when there are multiple changes made to already existing code

Question 15

partial regression testing

Answer 15

test issues when new code is added

make sure that system is performing correctly after new code is added

Question 16

what are user acceptance tests

Answer 16

final phase of testing to ensure that the software is ready for production by making sure that it is what the user wanted and it usable and user friendly

Question 17

Alpha testing

Answer 17

often conducted in software house or with super users

Question 18

beta testing

Answer 18

conducted with actual users of the system

Question 19

types of security testing

Answer 19

vulnerabilitty scanning
security scanning
penetration testing
risk assessment
security auditing
ethical hacking
posture assessment

Question 20

stubs

Answer 20

used when sub programs are under development
used in top down intergration testing
top most module is tested first
can simulate the behavior of lower level modules that are not integrated
stubs are called programs

Question 21

Drivers

Answer 21

used in bottom up integration testing
used when main programs are under development
lowest module is tested first
simulate the behavior of upper level modules that are not integrated
drivers are the calling programs
