      Solution

      Unit testing is a crucial phase in the software development lifecycle where individual components or functions of an application are tested in isolation from the rest of the system. The primary goal of unit testing is to validate that each unit of the software performs as expected, producing the correct output for given inputs. This process helps developers identify and fix bugs early in the development cycle, which improves the reliability and maintainability of the code.
