How to Unit Test Your Go Application

Go is a programming language that was developed around 2007 at Google to address many of the “system programming” tasks typically handled by C. While the syntax of Go is familiar to C programmers, it introduces more powerful and rigorous static typing. Additionally, Go offers the readability and memory safety found in languages like JavaScript and Python. The language also places a strong emphasis on performance, particularly in terms of its built-in concurrency features. Go provides a reference compiler, standard library, and a variety of other tools, all of which are freely available as open source.

A Guide to Rust vs. Golang: Performance and Uses

Rust and Go are fast, compelling, and modern alternatives to programming languages like C/C++. Both provide built-in concurrency models to take advantage of multiple CPUs. But is there a clear advantage to either Rust or Go that makes one a better programming language? More importantly, which one is right for your use case?

The GOPATH in Golang

A team of Google employees designed the Go programming language in 2007 to help developers make better use of high-performance, networked, multi-core computing chips. Well over a million coders around the world now work in Go.

Using the Go Unit Testing Command: go test

Unit testing verifies the functionality of a specific section of code in isolation. In the Go language, go test is the built-in command that runs unit tests, example functions, and benchmarks; does code profiling, and performs code coverage analysis. This guide provides an introduction to unit testing in Go.

Getting Started with Go

Introduction

Go is a modern, open source, and general-purpose programming language that began as an internal Google project and was officially announced at the end of 2009. Go was inspired by many other programming languages including C, Pascal, Alef, and Oberon. Its spiritual fathers were Robert Griesemer, Ken Thomson, and Rob Pike, who all designed Go as a language for professional programmers that want to build reliable, robust, and efficient software. Apart from its syntax and its standard functions, Go comes with a rich standard library.

A Tutorial for Learning Structs in Go

Introduction

Go’s array, slice, and map types can be used to group multiple elements, but they cannot hold values of multiple data types. When you need to group different types of variables and create new data types, you can use structs.

A Tutorial for Learning Go Functions, Loops, and Errors

After you’ve learned the syntax of a simple “Hello World” script in Go, you’ll likely want to start making more complicated programs. This guide will introduce language constructs that help with structuring your programs, including:
