The purpose of unit testing
In short, it's a test of all the logic after we add or change some code, especially after we've modified it (whether it's adding new features, modifying bugs), and we can do it again . To reduce the recurrence of problems that we have solved even before they were released.
This is mainly done by using MOCKMVC to unit test the controller of our system.
