Final answer:
The statement that in (3-point) boundary value analysis, test cases are set just inside and just outside the boundaries of equivalence classes is true, as this approach aims to uncover any errors at the edges of equivalence classes.
Step-by-step explanation:
In (3-point) boundary value analysis, the main goal is to set test cases at, and just inside and just outside the boundaries of the equivalence classes to thoroughly test the edge cases. This approach to software testing is designed to find any errors that are present at the boundaries between equivalence classes, which is where errors are most likely to occur. Therefore, when mentioning the 3-point boundary value analysis, it is true that we set test cases just inside and just outside the boundaries of the equivalence classes.
