Test Analysis and Test Design

In a tax system, earnings of 4.000 are tax-free; the next 1.500 are taxed at 10%, the following 28.000 at 20%, and the remaining amount above at 40%. All values are rounded to 1.

Which test case could result from boundary value analysis?

Explanation

The boundary between the 20% band and the 40% band is 33,500: 4,000 + 1,500 + 28,000. A boundary-value test includes a value immediately next to that limit, such as 33,501.
