Writing an HTTP Server in Go from Scratch: Part 2

Follow along while I improve the HTTPServer I wrote from scratch in Go. Last year I wrote a blog post explaining how I built my HTTP Server in Golang by following a Coder Crafters, I got some good feedback on it and improved the HTTP Server quite a bit, let’s dive into the changes! The git repository is still available if you want to look at the whole codebase. The first unit test Let’s start by adding a unit test, I was relying on the Codecrafters test suite but now I want to have some of my own unit tests. This should mimic the first stage of the Codecrafters test suit: func TestServerStart (t * testing.T) { // Start the server router := server. NewServer () go router. Start () // Give the server a moment to start time. Sleep ( 100 * time.Millisecond) // Not the most robust, good enough to start // Try to connect to the server conn, err := net.
