What is unit testing Meaning?
Unit testing is a method of testing by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use. A unit is the smallest testable part of an application. In procedural programming a unit may be an entire module, but it is more commonly an individual function or procedure. In object-oriented programming, a unit is often an entire interface, such as a class or a group of related classes. But it can also be an individual method, variable, attribute, or interaction involving one or more classes.
