Chapter 6 Definitions

Question 1

What is non execution based testing?

Answer 1

Testing methods that do not involve running the code, such as reviews and inspections

Question 2

What is execution based testing?

Answer 2

Testing performed by running the software with specific inputs and observing the outputs.

Question 3

What are two non-execution based testing methods?

Answer 3

Inspections and walkthroughs

Question 4

What are inspections?

Answer 4

A formal, non-execution based testing method that uses a five step process to find faults and take action on them

Question 5

What are walkthroughs?

Answer 5

A non-formal, non-execution based testing method that tries to find faults by reading the documentation in a group and verbalizing the steps

Question 6

What are the strengths and weaknesses of reviews?

Answer 6

Reviews can be effective
– Faults are detected early in the process

Reviews are less effective if the process is
inadequate
– Large-scale software should consist of smaller, largely independent pieces
– The documentation of the previous workflows has to be
complete and available online

Question 7

What are things that should to be tested?

Answer 7

• Correctness
  – Utility
  – Reliability
  – Robustness
  – Performance

Question 8

What is correctness proof?

Answer 8

A mathematical approach to demonstrate the correctness of a program based on its specifications and logical reasoning

Question 9

When are correctness proofs vital?

Answer 9

– When human lives are at stake
– When indicated by cost–benefit analysis
– When the risk of not proving is too great
