Can someone please help me summarize this I need it for a small presentation for my Computer Science class Testing

When testing a program that contains a loop, we should focus first on the input that determines the number of iterations. In our program, this value is the number of years. We enter a value that yields the smallest possible number of iterations, then increase this number by 1, then use a slightly larger number, such as 5, and finally we use a number close to the maximum expected, such as 50 (in our problem domain, probably the largest realistic period of an investment). The values of the other inputs, such as the investment amount and the rate in our program, should be reasonably small and stay fixed for this phase of the testing. If the program produces correct outputs for all of these inputs, we can be confident that the loop is working correctly.

In the next phase of testing, we examine the effects of the other inputs on the results, including their format. We know that the other two inputs to our programs, the investment and the rate, already produce correct results for small values. A reasonable strategy might be to test a large investment amount with the smallest and largest number of years and a small rate, and then with the largest number of years and the largest reasonable rate. Table 3-1 organizes these sets of test data for the program.
