Study of unit testing in Java, based on McCabe's cyclomatic complexity for the choice of test cases, as well as the use of the border testing strategy.
To carry out the study, two basic classes were used, one with the object of calculating a person's average body mass index and returning their status in a String.
The other has the objective of applying an aliquot to the value of a product, according to the rate of each federative unit in Brazil, and returning the new value as a Double.

| Over ideal weight | <= 27.3 < 32.3 | <= 27.8 < 31.1 |
| Obese | >= 32.3 | >= 31.1 |
