What are the differences between line coverage and branch coverage?
Line coverage measures the percentage of executable lines of code that have been tested, while branch coverage measures the percentage of branches (or decision points) that have been executed.
Why is branch coverage considered more comprehensive than line coverage?
Branch coverage is more comprehensive because it ensures that all possible paths through the code are tested, not just that each line has been executed.
Can you give an example to illustrate the difference?
Sure! In a simple if-else statement, line coverage might show that the line was executed, but branch coverage would ensure both the 'if' and 'else' paths were tested.
How can I improve both line and branch coverage in my tests?
You can improve coverage by writing more unit tests that target different paths and conditions in your code, ensuring all scenarios are tested.
