Branch Testing is a software testing technique that focuses on verifying the execution of decision points in the code, such as conditional statements (if-else), loops, and switch-case constructs, to ensure that all possible branches or paths are exercised at least once. Key aspects:
Objective:
- Test all possible outcomes of conditional statements
- Ensure correct program flow for all decisions
Test Case Design:
- Create tests for each branch condition
- Include both true and false outcomes
Coverage Criteria:
- Aim for 100% branch coverage
- May require multiple test cases per branch
Challenges:
- Complex conditions may require many tests
- Some branches may be difficult to trigger
Benefits:
- Thorough testing of program logic
- Identifies errors in conditional statements
Branch Testing is crucial for verifying correct program behaviour in all scenarios.
