Branch Coverage is a software testing metric that measures the extent to which the decision points (branches) in the code, such as if-else conditions, loops, or switch-case statements, have been executed during testing. It ensures that every possible branch in the control flow has been tested at least once. Features include:
Definition:
- Percentage of branches executed by tests
- Indicates thoroughness of testing
Calculation:
- (Executed Branches / Total Branches) * 100
- A higher percentage indicates better coverage
Importance:
- Ensures all decision paths are tested
- Helps identify untested scenarios
Tools:
- Code coverage tools
- Static analysis software
Limitations:
- Does not guarantee all combinations are tested
- May not catch all logic errors
Branch Coverage is a key metric for assessing test completeness
