What Is Unit Testing Explain It with Example?
Unit testingis a confusing part of the software development process. Unit testing involves individually testing unit of code separately to make sure that it works on its own, independent of the other units.
Unit testing is essentially a set of path, test performed to examine the several different paths through the modules. Unit testing is remarkably done by programmers with the help of Unit framework (like J Unit, CPP Unit etc. depending up on the language source code is written). Unit testing is usually an automated process and performed within the programmers IDE.

Unit testing is an action used to validate that separate units of source code remains working properly. Example: - A function, method, Loop or statement in program is working fine. It is executed by the Developer. In unit testing Individual functions or procedures are tested to make sure that they are operating correctly and all components are tested individually.
Unit testing is a strategy that utilizes the white-box method and concentrates on testing individual programming units. These units are sometimes specifying to as modules or atomic modules and they represent the smallest programming entity.
Unit Testing Example
Example of Unit testing is explain below
For example you are testing a function; whether loop or statement in a program is working properly or not than this is called as unit testing. A beneficial example of a framework that allows automated unit testing is JUNIT (a unit testing framework for java). XUnit [20] is a more general framework which supports other languages like C#, ASP, C++, Delphi and Python to name a few.
1) Module Interface test: In module interface test, it is checked whether the information is properly flowing in to the program unit (or module) and properly happen out of it or not.
2) Local data structures: These are tested to inquiry if the local data within the module is stored properly or not.
3) Boundary conditions: It is observed that much software often fails at boundary related conditions. That's why boundary related conditions are always tested to make safe that the program is properly working at its boundary conditions.
4) Independent paths:All independent paths are tested to see that they are properly executing their task and terminating at the end of the program.
5) Error handling paths:These are tested to review if errors are handled properly by them or not.
Conclusion: At last we conclude that Unit testing focuses on the distinct modules of the product.
