GoLang Unit Testing and Mock Testing Tutorial

In this video we are going to learn what a unit test and what mocking and stubs are. We learn how to create go files for testing, using the testing library, and set up basic unit tests plus using a slice to run a multitude of tests.

We also use the httptest package to set up a mock server to mimic getting JSON data from the web. So that we learn how to do mock testing in golang. There are a lot of different ways to do mock testing, in this tutorial we set up a simple mock test using a stub server to return JSON data for testing.
