The Classification Tree Technique is a black-box testing method used to systematically design test cases. It involves breaking down the input domain of the system under test into classifications (categories) and their corresponding classes (specific values or ranges) to ensure comprehensive coverage of test scenarios. Steps include:
Create a Classification Tree:
- Identify system attributes
- Define classifications and classes
Generate Combinations:
- Combine classes from different classifications
Design Test Cases:
- Create test cases for each combination
Prioritise Tests:
- Focus on important combinations
Execute Tests:
- Run tests and analyse results
This technique ensures systematic coverage of test scenarios.
