Testing is necessary because software is likely to have faults, to learn about the reliability of the software, and because testing is included in the project plan. Additionally, failures can be very expensive, which further emphasizes the importance of testing.

2. Customer wants brown bread and sliced bread
3. Customer wants white bread
Therefore, three tests are required to achieve full branch coverage.Rate this question:
