In computer programming, unit testing is a software testing method, which is used to test a single unit of source code, a collection of one or more computer program modules, and related control data, use process and operation process to determine whether they are suitable for use. In short, when we are doing unit tests, we only test one code unit, only one method at a time, excluding all other components that interact with the component under test.
