To answer this question, let's analyze each option:
Option A) Find more faults - This option suggests that the prioritization of tests helps in finding more faults. However, while prioritizing tests can potentially help in identifying and fixing faults, it does not necessarily guarantee finding more faults in comparison to other options.
Option B) Do best testing in the time available - This option suggests that prioritizing tests allows us to perform the best testing within the given time constraints. Prioritizing tests helps in identifying critical areas and focusing on them first, ensuring that the most important testing is done within the available time. This option aligns with the concept of prioritization.
Option C) Do more effective testing - This option implies that prioritizing tests leads to more effective testing. While it is true that prioritization can help in focusing on critical areas, it does not necessarily guarantee more effective testing in comparison to other options.
Option D) Shorten the time required for testing - This option suggests that prioritizing tests helps in reducing the overall time required for testing. While prioritization can help in identifying critical areas and focusing on them first, it does not necessarily shorten the overall testing time.
Based on the analysis, the correct answer is B) do best testing in the time available. Prioritizing tests ensures that the most important testing is done within the given time constraints.
