• Example for iterative method: int fib(int n) { int a = 0, b = 1, c; for(int i = 2; i <= n; i++) { c = a + b; a = b; b = c; } return b; }

• Example for recursive method: int fib(int n) { if(n <= 1) return n; return fib(n-1) + f

• Use assertions to check the expected behavior of the code under test

• Mock dependencies or use dependency injection to isolate units for testing

• Run tests regularly to catc
