Testing Types

Question 1

Functionality Testing

Answer 1

Making sure all the requirements (features) are properly implemented

Question 2

Volume testing

Answer 2

Testing of the application being able to function with data/file of specified size/volume

Question 3

What is Unit testing?

Answer 3

• White box testing. Isolating other units of software and concentrating on a single unit.

Question 4

Integration testing

Answer 4

Testing 2 or more units together (white box). Black box: 2+ functional modules/features

Question 5

System testing

Answer 5

Testing the entire system (application) with no regards to individual units

Question 6

LEVELS OF TESTING

Answer 6

Unit testing
Integration testing
System testing
User Acceptance Test

Question 7

End-to-End testing

Answer 7

System level test similar to execution of a use case - testing a completed business transaction

Question 8

What is API Testing

Answer 8

White box testing of libraries (APIs) developed to be reused multiple times in that project

Question 9

Rest API testing

Answer 9

Gray box - testing Web Services (how the app communicates from server side to client side).
Could be done manually (Postman) or automated

Question 10

Browser compatibility testing (cross-browser)?

Answer 10

• web page looks/works regardless of the browser used to see the page
  Operating system (cross-platform) Compatibility? - web page looks the same in the browser while moving to other operating systems

Question 11

Define Equivalence class?

Answer 11

Group of inputs with an exact same EXPECTED output - we need 1 test case for the class

Question 12

Equivalence partitioning?

Answer 12

The process of identifying classes and their boundaries

Question 13

What is error handling testing (exception handling)?

Answer 13

• has nothing to do with what user will experience
• exception is a catastrophic CODE problem - dividing by ZERO, for example - program should terminate
• error handling is a part of the application CODE
• white box testing

Question 14

Localization testing

Answer 14

Testing of translation, currencies, time/date, and other country/language specific issues

Question 15

Internationalization testing

Answer 15

Making sure that the application is ajustable to various languages, locations, time/date, etc.

Question 16

Performance testing

Answer 16

Monitor performance degradation of the SYSTEM under SPECIFIC workload (within the working limits, 70% of MAX) for a set time (f.e. 4 hours)

Question 17

Load testing

Answer 17

Performance testing with focus on database/backend performance (within expected/Specific load)

Question 18

Stress testing

Answer 18

Peformance testing at EXTREME load

Question 19

What is Manual Testing?

Answer 19

Human execution of test procedures without using test automation tools or programming languages.

Question 20

What is Test Automation?

Answer 20

A process of writing and executing a computer program to do testing.

Question 21

What is Non-Functional Testing?

Answer 21

Non-Functional testing is being done to test attributes of a component or system that do not relate to functionality: Reliability; Efficiency; Usability; Maintainability; Compatibility, etc

Question 22

What is Exploratory Testing?

Answer 22

Exploratory testing is when the tester “explores” an application. No requirements. Tester, based on experience and creativity, learns things and generates new tests to run. Black box testing. Manual testing.

Question 23

What is Ad hoc Testing?

Answer 23

Simplified form of Exploratory Testing where Planning, Executing and Learning are happening at the same time.

Question 24

What is Installation Testing?

Answer 24

Installation testing verifies that the system is installed and set up correctly to work in a specified software/hardware environment.

Question 25

What is Alpha Testing ?

Answer 25

Alpha testing takes place at developers’ site. Making sure the application has the right look and feel. Functionality is not expected to be fully in place.

Question 26

What is Beta Testing?

Answer 26

Beta testing takes place at customers’ sites, and involves testing by a group of customers who use the system at their own locations and provide feedback, before the system is released to other customers.

Question 27

What is Recoverability Testing?

Answer 27

Recoverability testing is aimed at showing that if the system fails:
How it will re-establish a specified level of performance?
How it will recover directly affected data?

Question 28

What is Security Testing?

Answer 28

Security testing is conducted to test that:
System data is protected;
How system prevents the intrusion by hackers.
