Coverage Criteria define the goals for testing completeness by specifying the extent to which various aspects of the code, functionality, or requirements must be tested. These criteria are used to measure and ensure the adequacy of test cases in covering specific elements within the system, such as statements, branches, paths, or conditions. Aspects include:
Types:
- Statement coverage criteria
- Decision coverage criteria
- Condition coverage criteria
- Path coverage criteria
Purpose:
- Guide test case design
- Set testing objectives
- Measure testing thoroughness
Selection Factors:
- Risk assessment
- Regulatory requirements
- Time and resource constraints
Implementation:
- Define criteria for each test level
- Create test cases to meet the criteria
- Monitor and report coverage achieved
Challenges:
- Balancing coverage and efficiency
- Handling infeasible paths
- Interpreting coverage results
Coverage criteria help ensure comprehensive and targeted testing efforts.
