What are the best practices for achieving branch coverage in testing?
To achieve effective branch coverage, consider the following best practices: 1. Write comprehensive test cases that cover all branches. 2. Use code coverage tools to identify untested branches. 3. Prioritize testing for critical paths in your code. 4. Regularly review and update tests as code changes.
How do I measure branch coverage?
You can measure branch coverage using code coverage tools like JaCoCo, Istanbul, or Cobertura. These tools analyze your code and report the percentage of branches that have been executed during testing.
What is the difference between branch coverage and line coverage?
Branch coverage measures whether each possible branch (true/false) in control structures has been executed, while line coverage measures whether each line of code has been executed. Branch coverage is generally more comprehensive.
Can you give an example of a branch coverage test case?
Sure! For a simple if-else statement, you would need at least two test cases: one that triggers the 'if' branch and another that triggers the 'else' branch to achieve full branch coverage.
