Unit testing HTTP calls to external services is pretty easy in Go. Let’s say we have some code that makes HTTP requests like so: package something import ( “net/http” ) func SomeFunc(url) string { rs, _ := http.Get(url) defer rs.Body.Close() body, _ := ioutil.ReadAll(rs) return string(body) } We can test if the request is made…

A simple GET request can be made like this: package main import ( “net/http” “ioutil” ) func main() { // Make a get request rs, err := http.Get(“https://google.com”) // Process response if err != nil { panic(err) // More idiomatic way would be to print the error and die unless it’s a serious error }…

Polymorphism is a bit different in Go. It supports polymorphism only through interfaces (and not through inheritance). To help you understand better, here is an example: import “fmt” type Car interface { func Drive() } type Lamborgini struct { // Implement the Car interface func Drive() { fmt.Println(“Driving”) } } func driveACar(car Car) { car.Drive()…

A friend of mine sent me an interesting quote by Imam Ghazali which puts things in perspective. Your time should not be without any structure, such that you occupy yourself arbitrarily with whatever comes along. Rather, you must take account of yourself and order your worship during the day and the night, assigning to each…

Go (or Golang) doesn’t have the concept of classes. The class equivalent in Go loos like this: // Make a Car class equivalent type Car struct { // object properties go here doors int } // Get the number of doors func (car *Car) Doors() int { return car.doors } // Set the number of…

I have been in search for a language I can use for web programming, writing computationally intensive and general scripting among other things. The language that came close to fitting all of these things was Racket, a dialect of Chicken Lisp. It can even do geometry drawings. However, there were issues with it so I…

This is a question I get asked a lot. Mostly by those who are just starting off their career as programmers/developers, but often times also by veterans of IT field. Recently, I found myself asking that question when I came to the realization that PHP, as a language was not as much in demand as…
