volume_mute

Which of the following are recommended guidelines for testing programs that process sequences, arrays, or lists? Select all that apply.

Only test sequences with an even number of elements to avoid rounding issues

Use different sequences of different sizes in different tests

Test exclusively with the maximum allowed sequence length

Test with an empty sequence if the specification allows it

Derive tests so that the first, middle, and last elements of the sequence are accessed

Test with sequences that have only a single value

Correct Answer

(1) Test with sequences that have only a single value

(2) Use different sequences of different sizes in different tests

(3) Derive tests so that the first, middle, and last elements of the sequence are accessed

Explanation

The three recommended guidelines for sequence testing are: (1) test with single-value sequences to expose assumptions; (2) use different sequence sizes to reduce accidental correct outputs from defective code; (3) access first, middle, and last elements to reveal problems at partition boundaries.
