Testing Approaches - Black Box Testing

Question 1

What is Black Box Testing?

Answer 1

A method that analyzes the functionality of a software/application without knowing much about the itnernal structure/design of the item being tested.

Question 2

What are the two fundamental types of Black Box Testing?

Answer 2

Functional Testing and Non-Functional Testing

Question 3

What are some examples of Non-Functional Testing?

Answer 3

Examples include Usability Testing, Load Testing, Performance Testing, Compatibility Testing, Stress Testing, and Scalability Testing.

Functional Testing are included in the “Testing Approaches” deck

Question 4

What are the advantages of Black Box Testing?

Answer 4

Includes not needing technical background, independence of testers and developers, effectiveness for large and complex applications, and early detection of defects.

Question 5

What are the disadvantages of Black Box Testing?

Answer 5

Includes the possibility of ignoring possible conditions, the risk of testing less within a time frame, and incomplete test coverage for large and complex projects.

Question 6

What is the goal of Black Box Testing in the software development life cycle?

Answer 6

To verify the functionality of the system and identify defects throughout the development process.

Question 7

What is Equivalence Partitioning?

Answer 7

Dividing inputs into classes/groups based on outcome similarity. Test using one value per group.

Question 8

What is Boundary Value Analysis?

Answer 8

Testing values at boundaries where behavior changes. Includes valid and invalid inputs.

Question 9

What is Decision Table Testing?

Answer 9

Creating test cases from decision tables based on logical conditions/actions.

Question 10

What is State Transition Testing?

Answer 10

Testing different states of system based on events/conditions using state transition diagrams.

Question 11

What is Error Guessing?

Answer 11

Experience-based testing of common developer mistakes like divide by zero, null values.

Question 12

What are Graph-Based Testing Methods?

Answer 12

Identifying objects and relationships from object graph to create test cases.

Question 13

What is Comparison Testing?

Answer 13

Comparing independent versions of same software for testing.

Question 14

Black Box Testing requires a technical background in coding.

Answer 14

False

Question 14

Usability Testing and Load Testing are examples of Non-Functional Black Box Testing.

Answer 14

True

Question 14

State Transition Testing is more effective for simple applications.

Answer 14

False

Question 14

Equivalence Partitioning uses every possible input value for testing.

Answer 14

False

Question 15

Boundary Value Analysis tests values at the boundaries where behavior changes.

Answer 15

False

Question 15

Decision Table Testing is unrelated to logical conditions.

Answer 15

False

Question 15

Error Guessing relies solely on documented requirements.

Answer 15

False

Question 16

Comparison Testing can use different software versions.

Answer 16

True

Question 16

An advantage of Black Box Testing is early defect detection.

Answer 16

True

Question 16

White Box Testing has knowledge of the internal code structure.

Answer 16

True

Question 16

Graph-Based Testing Methods identify objects and relationships visually.

Answer 16

True

Question 17

Black Box Testing guarantees complete test coverage for all projects.

Answer 17

False

Question 18

Black Box Testing is only performed at the end of the development cycle.

Answer 18

False
