Combinatorial Testing is a black-box testing technique that focuses on generating test cases by combining input values, parameters, or configurations in systematic ways. It is particularly effective in identifying defects caused by interactions between different inputs or system components. Key aspects include:
Test Design:
- Combine multiple parameter values
- Create efficient test cases
Coverage:
- Test all possible combinations of parameters
- Reduce the number of test cases
Techniques:
- Pairwise testing
- Orthogonal array testing
- All-pairs testing
Benefits:
- Efficient test coverage
- Detect interaction faults
Challenges:
- Selecting appropriate parameters
- Balancing coverage and test effort
This technique optimises test case generation for complex systems
