Unit 2 Testing and Test Plans
Iterative testing, white-box, black-box, system, alpha, beta and A/B testing, effective plans, navigation, assets, load time and scripts.
How to study for CCEA GCSE Digital Technology
Connect precise digital concepts to scenario evidence, design decisions, testing and evaluation, then rehearse the controlled-practice lifecycle under your centre's current CCEA instructions.
Core concepts
Concept 1
Testing should occur iteratively so defects and requirement gaps are found while the design can still be refined.
Exam cue: Choose the testing approach from who tests, what evidence is visible and what is being compared.
Concept 2
White-box, black-box, system, alpha, beta and A/B approaches answer different questions about internal logic, behaviour, integration and user preference.
Exam cue: Include normal, boundary and failure behaviour for navigation, assets and scripts.
Concept 3
An effective test plan records test purpose, inputs or action, expected outcome, actual outcome, result and follow-up.
Exam cue: Tie each test to a requirement and expected result before execution.
Risk pitfalls and guardrails
Recording only tests that pass.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Calling user preference feedback a substitute for functional testing.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Writing an expected result after seeing the actual outcome.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Memory anchors
White-box testing
Testing informed by the internal code or logic structure.
Black-box testing
Testing observable behaviour from inputs and outputs.
System testing
Testing the complete integrated solution.
Alpha testing
Pre-release testing within or closely controlled by the developer organisation.
Beta testing
Pre-release testing by representative external users.
A/B testing
Comparing two design variants using user-response evidence.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
