Lesson 2 Main Testing Types and Software Bug Classification

Question 1

What are the main testing types?

Answer 1

Functional & Non-functional

Question 2

What is functional testing?

Answer 2

Question 3

What is non-functional testing?

Answer 3

Non-Functional Testing is a type of testing used to evaluate a software application’s performance, usability, dependability, and other non-functional characteristics.

It is intended to test a system’s readiness according to non-functional criteria that functional testing never considers.

Question 4

Types of functional testing

Answer 4

Unit testing
Integration testing
Sanity testing
Smoke testing
Interface testing
Regression testing
Acceptance testing

Question 5

Types of non-functional testing

Answer 5

Load testing
Localization testing
Performance testing
Security testing
Stress testing
Usability testing

Question 6

What is unit testing?

Answer 6

Software testing where individual units/components of a software are testing (usually made by developers)

Testing one thing a time

Question 7

What is integration testing?

Answer 7

Software testing where individual units are combined and tested as a group (usually made by developers)

Bring multiple functions together to see how they interact

Question 8

What is sanity testing?

Answer 8

Performed after receiving a software build with changes in code or functionality to ensure the bugs have been fixed

Ensure it loads without crashing, usually developers do this testing

Question 9

What is smoke testing?

Answer 9

Performed after receiving a software build to ensure the critical functionalities of the program are working fine

This is executed before any detailed functional or regression tests are done

Question 10

What is interface testing?

Answer 10

Software testing to check how the user interface looks on the device

Question 11

What is regression testing?

Answer 11

Performed to confirm that a recent program or code change has not affected existing features (try to break the software)

It ensures the old code still works once the new code changes are done

Question 12

What is acceptance testing?

Answer 12

Software testing where a system is tested for acceptability

Building testing around the business requirements and access if it is acceptable for delivery

Question 13

What is load testing?

Answer 13

Checks how the application behaves during normal and high loads

This is how many users can an application process

Question 14

What is localization testing?

Answer 14

It is meant to customize a website or app according to the targeted language, region, audience preferences, and area-based regulations (country or state)

It aims to serve a customized user experience by curating features and offerings for individuals according to where they are and what they might prefer

Question 15

What is performance testing?

Answer 15

Determines the speed of a computer, network, or device

Question 16

What is security testing?

Answer 16

Checking for anything that allows hackers to get in

Grown into cybersecurity industry

Question 17

What is stress testing?

Answer 17

Uses an auto-generated simulation model to check all hypothetical scenarios

Taking the software over the requirements for a certain amount of time to see when it will crash

Question 18

What is usability testing?

Question 19

What is alpha testing?

Answer 19

Performed to identify all possible bugs before the product is released to end-user

Question 20

What is beta testing?

Answer 20

Releasing a beta version of the software to a limited number of end-users to obtain feedback on the quality

Gaming - allows a small number of users to test the game before it is released

Question 21

What is end-to-end (e2e) testing?

Answer 21

Checks whether an application flow from start to finish is behaving as expected (over the full user journey)

Ex. Shopping on Amazon - login, search for product, add to cart, checkout, payment, order confirmation

Question 22

Testing workflow

Answer 22

Step 1: Sanity testing - does it still work
Step 2: Smoke testing - do the main features work (does it load)
Step 3: Regression testing - does everything else work (larger scale testing)

Question 23

What is positive testing?

Answer 23

Uses the valid data as input and checks whether an application behaves as expected with positive inputs

Question 24

What is negative testing?

Answer 24

Ensure that the application can gracefully handle invalid input or unexpected user behavior

Question 25

What is black box testing?

Answer 25

You don’t see inside it

Ex. ATM

Question 26

What is white box testing?

Answer 26

You can see through the box - you have actual access to the code

Question 27

What is grey box testing?

Answer 27

You can see a little through the box - you have some access to the code but not fully

Question 28

Positive, negative, boundary

Answer 28

If the input data used is within the boundary value limits, it is positive testing

If the input data is outside the boundary value limits, it is negative testing

Ex. Testing users age with allowed register 18 to 150

Question 29

Bug classifications

Answer 29

P0 - Blocker
P1 - Critical
P2 - Major
P3 - Trivial
P4 - Minor

P0 is the highest and most important to fix
