What is Unit Testing?
By ‘unit’, we refer to the smallest testable component of a software. Depending upon the programming involved, it could be anything – an individual program, a function or a method derived from a class.
So, as the name indicates, Unit Testing is a type of Functional Testing where separate units or individual components of a software are tested. Generally, there are one or more inputs and a single output. The output of the ‘unit’ is then tested for multiple input values.
The objective behind Unit Testing is to ascertain that each individual functional component of the software performs as originally designed and expected. Performed using the White Box Testing procedure, Unit Testing precedes all other testing methods and is performed even before Integration Testing.

Benefits of Unit Testing
A lot of testers may not pay heed to Unit Testing, but it is in fact the most important level of testing. Testers must neglect Unit Testing at their own peril.
So, what are the benefits of Unit Testing? If unit tests are written and performed for particular units, then every time some code is changed, it becomes efficient to point out any unwanted results on account of that change. So, it enhances confidence while updating or maintaining the code.
Also, it is important from pure economics point of view, because the time and cost of fixing a bug is less during the unit testing phase than at any other higher levels of testing. Another advantage is that since the code needs to be modular for Unit Testing, it also happens to be reusable.
