Assume you have the following JavaDoc for a method: /** * Determines water usage tier for billing. * * – gallons must be non-negative, otherwise throws IllegalArgumentException * – Tier 1: 0-5000 gallons: $0.01/gallon * – Tier 2: 5001-10000 gallons: $0.015/gallon * – Tier 3: 10001-20000 gallons: $0.02/gallon * – Tier 4: 20001+ gallons: $0.03/gallon * * @param gallons water usage in gallons * @return tier number (1, 2, 3, or 4) */ public int getWaterUsageTier(int gallons); For the above example you should do a detailed Black-box test design. Create Equivalence Partitions and do a Boundary Value analysis – describe. Taking these into account design at least 6 test cases that you think are most important based on your partitions (I do not want Java code here, I want your test description). Make sure you mention the partitions and/or BV in the test cases you design. Then write one Unit Test (the syntax does not have to be 100% correct but should of course be in Java).
