Most developers already complete some sort of unit testing throughout the application build. Unit testing focuses on getting developers to test application code as soon as it is written. This process achieves the testing goal of ensuring every line of code executes properly. Satisfying this objective certifies that code works and can be used in larger units.
Unit Testing Defined
Unit testing is the process of testing the code in a single component to check the implementation for correctness. Unit tests do not validate requirements, they only focus on checking that the code executes as intended.
