CISA Certified Information Systems Auditor – Question2881 - CISA Certified Information Systems Auditor

Which of the following is MOST critical when creating data for testing the logic in a new or modified application system?

A. A sufficient quantity of data for each test case
B. Data representing conditions that are expected in actual processing
C. Completing the test on schedule
D. A random sample of actual data

Correct Answer: B

Explanation:

Explanation: Selecting the right kind of data is key in testing a computer system. The data should not only include valid and invalid data but should be representative of actual processing; quality is more important than quantity. It is more important to have adequate test data than to complete the testing on schedule. It is unlikely that a random sample of actual data would cover all test conditions and provide a reasonable representation of actual data.
