Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils discover how iteration is used to replicate parts of a program. They will analyse the difference between count and condition controlled iteration and how trace tables can be used to trace through loops. They will explore data validation techniques and robust program design.
Lesson Summary
You will learn to develop a program and apply testing techniques to ensure that it works correctly.
Key Notes
- Completing an implementation ensures that all intended functionality is present.
- Testing checks that code behaves correctly and meets requirements.
Vocabulary To Learn
- test plan: a document that sets out the tests that will be carried out during testing
- test data: the input values used to check whether a program works correctly during testing and to see how it behaves in different situations
Common Mistakes To Avoid
- I finished the code and it runs, so I don't need to test it.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Completing an implementation ensures that all intended functionality is present. Testing checks that code behaves correctly and meets requirements.
2. Define this computing term and give one practical example. 'test plan'
a document that sets out the tests that will be carried out during testing. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: I finished the code and it runs, so I don't need to test it. Correction: Just because a program runs doesn't mean it works correctly in all situations. Testing helps find hidden errors, especially with unusual or unexpected inputs that you might not think of.
