Branch Coverage Testing is a software testing technique that aims to execute all possible branches in the code’s decision points (such as if-else statements, loops, and switch cases) to ensure that every branch has been tested for correctness at least once. Process involves:
Identify Branches:
- Analyse code for decision points
- Map out all possible paths
Design Tests:
- Create tests to cover each branch
- Ensure both true and false conditions are tested
Execute Tests:
- Run tests and track executed branches
- Use code coverage tools for measurement
Analyse Results:
- Identify uncovered branches
- Develop additional tests as needed
Benefits:
- Comprehensive logic testing
- Identifies dead code or unreachable branches
This technique ensures thorough testing of program decision logic.
