Have you tested the system with edge cases?

Yes, boundary testing (testing system at edge values) is an important part of verifying the reliability and stability of an application. For example, when testing a method that accepts numerical input, I checked its behavior at minimum, maximum, and out-of-range values. This helps identify errors related to overflow, incorrect exception handling, or faulty logic.

In Java, JUnit with parameterized tests is often used for such tests to verify different boundary cases.
