A Coverage Item is a specific element or aspect of a system that is tested to measure the extent of test coverage. Examples include individual statements, branches, conditions, or paths within the code, depending on the type of coverage being analysed (e.g., statement coverage, branch coverage). Characteristics include:
Types:
- Code statements
- Branches
- Conditions
- Functions
Identification:
- Static code analysis
- Test technique application
- Requirements analysis
Tracking:
- Mark items as covered when tested
- Calculate coverage percentages
- Identify uncovered items
Importance:
- Ensures thorough testing
- Guides test case creation
- Helps measure test effectiveness
Challenges:
- Identifying all relevant items
- Handling dynamically generated code
- Balancing coverage and testing effort
Coverage items form the basis for measuring test completeness and effectiveness.
