Definition

Testing runs the software with chosen data to find errors; debugging finds the cause of each error and fixes it.

Example: Testing finds that something is wrong; debugging finds out why and fixes it.

Found in: syllabus, 2025 HSC marking guidelines, school notes.

How to use it

A model sentence

General advice, built from the definition and example above

“Testing runs the software with chosen data to find errors; debugging finds the cause of each error and fixes it.” Then apply it: Testing finds that something is wrong; debugging finds out why and fixes it.

In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.

Official worked answer

Familiarisation Q5 (3 marks): Testing (test data) (3 marks): official criteria and sample answer

Criteria

3: Test data that thoroughly tests the algorithm, with expected outputs and reasons for inclusion. 2: Tests most boundaries and/or paths, with most expected outputs and reasons. 1: Some relevant information.

Sample answer

85 -> H (testing greater than 80). 80 -> H (boundary value 80). 60 -> P (between 50 and 80). 50 -> P (boundary value 50). 45 -> N (testing 'otherwise', below 50).
