Learn how to test individual functions, methods, modules, and packages using Go's built-in method for unit testing.

In unit testing, developers test individual functions, methods, modules, and packages to verify their correctness. Unit testing helps to find and fix bugs early in the development cycle, and it prevents regressions when refactoring. A good unit test can also serve as a form of documentation for developers who are new to the project.

In this tutorial, we’ll cover how to write unit tests in Go using the built-in testing package and several external tools. By the end of this article, you’ll understand concepts like table driven tests, dependency injection, and code coverage.
