2. Modular development
(a) Develop each class separately and test its methods.
(b) Example of testing the Book class:
book1 = Book(“Python Programming”, “Sarai Mkuvangwa”, “1234567890”, 3)
print(book1.checkout()) # Output: True
print(book1.available_copies) # Output: 2
Stage four: Testing and debugging
1. Testing
(a) Unit tests:
(i) Test individual methods for expected functionality.
