Q

What is the saturation region?

A

A region where no new defects are found and fixed

21
Q

Finding and fixing previously undiscovered defects leads to greater ____ in the program

A

Confidence

22
Q

T/F Any method of constructing functional tests is inadequate in comparison to code-based coverage criteria

A

T

23
Q

T/F In the software development life cycle testing activities should start as early as possible and should be focused on defined objectives

A

T

24

A

F

28
Q

At best, what is the practice for inspections?

A

Inspecting the key components

29
Q

T/F All products that are placed under CM and are used as a basis for subsequent development need to be subjected to successful completion of a formal inspection prior to its release to CM

A

T

30
Q

T/F The inspection needs to follow a rigorous process defined in the software development plan and should be based on agreed-to entry and exit criteria for that specific product

A

T

31
Q

T/F All products to be placed under CM should be inspected as far from their production as possible

A

F, as close to their production as feasible

32
Q

T/F Inspections should be conducted beginning with concept definition and ending with completion of the engineering process

A

T

33
Q

T/F Simple errors lead to simple failures

A

F, can lead to large failures

34
Q

Adequacy score or coverage, usually between _ and _

A

0 and 1

35
Q

T/F Weaknesses depend on the criteria used for assessment

A

T

36
Q

T/F In the saturation region, there are no more defects in the software
