Lecture 2: Functional Testing

Question 1

What is verification?

Answer 1

checking if product is built in the RIGHT WAY; i.e. build product that fulfill specs

Question 2

What is Validation?

Answer 2

checking if RIGHT PRODUCT is built!

i.e. meet user’s requirements/needs

Question 3

What is functional testing?

Answer 3

creating test based on program specifications; i.e. used for verification

Question 4

What are the alternative names of Functional Testing?

Answer 4

1. Black-box Testing

2. Specification-based Testing

Question 5

How do you use RANDOM Testing?

Answer 5

Randomly generate input values based on some constraints

Question 6

What is Systematic Testing?

Answer 6

attempt to select valuable inputs based on specification and constraints.

Question 7

What is systematic partition testing?

Answer 7

breaking down of ALL possible inputs into different partitions; so as to increase testing coverage

Question 8

Why do we use functional testing?

Answer 8

1. Timely
2. Effective
3. Widely Applicable
