A Classification Tree is a test design technique that organises and visualises test data domains and their classifications in a hierarchical structure. It is used to systematically create and select test cases by combining different classifications and values, ensuring comprehensive test coverage. Features include:
Structure:
- The root node represents the system under test
- Branches represent different classifications
- Leaves represent specific test values
Purpose:
- Organise test input data
- Identify test combinations
Creation Process:
- Identify key system attributes
- Define classifications for each attribute
- Determine relevant values for each classification
Benefits:
- Systematic test case generation
- Visual representation of test data
Applications:
Classification Trees help create comprehensive test suites efficiently.
