Unit Testing
Explore how unit testing verifies individual parts of your code to improve change management, simplify integration, and provide documentation. Understand common challenges and why unit testing complements broader testing strategies for quality web applications.
Unit testing is a method by which individual units of source code are tested. A unit is the smallest testable part of an application. In procedural programming, a unit may be an individual function or procedure. If you’re writing front-end code in React, it may be an individual component.
The implementation of unit testing can vary from being very manual (pencil and paper) to being formalized as a part of build automation.
Unit testing benefits
Facilitates change
Since test cases for all functions and methods are written, whenever a change in the overall system causes a fault, the unit that is causing it can quickly be identified and fixed.
Hence, unit testing allows the programmer to refactor code at a later date and make sure the module works correctly after other components are added.
