Chapter 7 Algorithm Design And Problem Solving: Unit 7.6: Test Data

Question 1

Define set of test data.

Answer 1

All the items of data required to work through a solution.

Question 2

Define normal data.

Answer 2

Should be used to work through the solution to find the actual result(s) and see if they are the same as the expected result(s).

Question 3

Define abnormal data.

Answer 3

A set of test data to test if the solution can prove that they do not do what they’re supposed to do. Abnormal data is data selected that would be rejected by the solution if the solution is working properly.

Question 4

Define extreme data.

Answer 4

When a certain range is given, extreme data are the largest and smallest values that normal data can take.

Question 5

Define boundary data.

Answer 5

This is used to establish where the largest and smallest values in a range occur. At each boundary two values are required, one is accepted and one is rejected.
