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
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.
