quality?

b. To formally asses the code using logical error detection techniques
c. To formally detect and subsequently correct code errors as they are found
d. The informally inspect the current state of the code seeking errors
21. Which artifact is necessary when developing a module test design?

a. Regression testing
b. Integration testing
c. System testing
d. Function testing
23. Previous test cases will be used to retest a software product after an improvements was made.
Which software testing principle is supported in this scenario?
a. Test cases must be written for input conditions that are invalid and unexpected as well
as for those that are valid and expected

, d. Testing is an extremely creative and intellectually challenging task.
24. Why is debugging with a storage dump the most inefficient of the brute force methods?
a. It contains program actions between the time of the dump and the time of the error that
can mask the clues needed to find the error
b. It requires a change of the program and such changes can mask the error, alter the
critical timing relationships, or introduce new errors.
c. It shows the program state at all times for error detection and for studying program
dynamics

examine the current stat of the program
