Which selective retest technique modified program to produce a different output than its original version that selects every test case ________ .A) CoverageB) MinimizationC) SafeD) MaximizationE) None of these

To modify a program to produce a different output than its original version, while selecting every test case, we need to use a selective retest technique. The options given are:

A) Coverage B) Minimization C) Safe D) Maximization E) None of these

To determine the correct answer, we need to understand the purpose of each technique in the context of selective retesting.

A) Coverage: This technique focuses on achieving a certain level of coverage, such as statement coverage or branch coverage. It does not necessarily guarantee a different output for every test case.

B) Minimization: This technique aims to minimize the number of test cases while still achieving a certain level of coverage. It does not necessarily guarantee a different output for every test case.

C) Safe: This option is not specific enough to determine its relevance to selective retesting. Without further information, it is difficult to determine if this technique would produce a different output for every test case.

D) Maximization: This technique aims to maximize the number of test cases while still achieving a certain level of coverage. It does not necessarily guarantee a different output for every test case.

E) None of these: This option suggests that none of the given techniques are suitable for modifying the program to produce a different output for every test case.

Based on the given options, the most appropriate answer would be E) None of these, as none of the techniques mentioned guarantee a different output for every test case while selecting every test case.
