Building Microservices API in Go - Unit Testing: Testing Routes

This video tutorial covers the process of testing routes in a Go application. It begins with an introduction to route testing, emphasizing the importance of isolating unit tests from external dependencies. The tutorial then explains how to set up mock implementations using the Go mock library and the mockgen tool. It demonstrates writing tests for a 'get all customers' route, including setting up mock services, creating HTTP requests, and asserting responses. The video concludes with a recap and encourages viewers to apply the learned concepts to other routes.
