volume_mute

Which three guidelines are recommended for testing programs that process sequences or arrays?

Test only with sequences containing unique values

Test with sequences that have only a single value

Always test with the maximum possible sequence length only

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

Use different sequences of different sizes in different tests

Only test sequences with an even number of elements

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 sequence testing guidelines are: (1) test with a single-value sequence - programmers often assume sequences have multiple values; (2) use different sizes - reduces accidental correct outputs from defective code; (3) access first, middle, and last elements - reveals problems at boundaries of array processing.
