Worked Solution & Example Answer:Charlie is developing an adding game - OCR - GCSE Computer Science - Question 5 - 2023 - Paper 2
Step 1
Explain why programs should be tested before use.
Answer
Programs should be tested before use to ensure they function as intended. Testing helps identify bugs and errors in the code that could lead to incorrect results or crashes during execution. Moreover, thorough testing improves the program's reliability, making the user experience more enjoyable and secure. It is crucial to verify that all features work correctly, especially when user input is involved, as mistakes can have significant repercussions.
Step 2
Complete the table by naming and describing one type of test that should be used on Charlie's program before releasing it.
Answer
| Functional Testing | This type of testing evaluates whether the program's functionalities operate according to the specified requirements. It checks that the user can correctly add two numbers and receive appropriate feedback based on their answers.
Step 3
Identify two methods of validation and explain how they can be used on this game.
Answer
Validation method 1: Range Check Use: A range check can be employed to ensure that the numbers input by the player fall within the acceptable range of 1 to 10. This avoids any out-of-bound errors and guarantees that the game functions as intended.
Validation method 2: Data Type Check Use: A data type check can validate that the player's input is a whole number. This prevents the game from crashing or producing unpredictable results if a user enters a non-numeric value.
