Tutorials on Go

The Go programming language is designed to address the types of software infrastructure issues Google faced back in late 2007. At this time, Google predominantly built their infrastructure using the programming languages C++, Java and Python. With a large codebase and having to adapt to rapid technological changes in both computing and key infrastructure components (e.g., multi-core processors, computer networks and clusters), Google found it difficult to remain productive within this environment using these languages. Not only does Go's design focus on improving the productivity of developers/engineers, but Go's design incorporates the best features of C++, Java and Python into a single statically-typed, compiled, high-performance language: Using Go and a lightweight router library, such as chi , writing and launching a simple RESTful API service requires little time and effort, even if you have no experience with Go. chi 's compatibility with the Go standard library package net/http , optional subpackages (middleware, render and docgen) and consistent API allows you to compose mantainable, modular services that run fast. Plus, these services can be deployed to and thrive in a production environment . If you have previously built RESTful APIs using Node.js and a minimal web application framework, such as Express.js , then you will find this to be quite similar! Below, I'm going to show you:

Testing plays a fundamental role in the development of quality software. Shipping and deploying software with undetected bugs and regressions opens up a can of terrible consequences such as losing the trust of end users or costing the business time and resources. In a large collaborative setting, having developers manually test each and every feature and user flow for bugs and regressions wastes valuable time that can be put towards improving other aspects of the software. As the codebase and team grows, this approach will not scale. By writing unit/integration/end-to-end tests, identifying and catching bugs and regressions throughout an entire codebase becomes a painless, automatable task that can easily be integrated into any continuous integration pipeline. Unlike most other languages, the Go programming language provides a built-in, standard library package for testing: testing . The testing package offers many utilities for automating the testing of Go source files. To write a test in Go, define a function with a name prefixed with Test (followed by a capitalized segment of text) and accepts an argument of struct type T , which contains methods for failing and skipping tests, running multiple tests in parallel, formatting test logs, etc. Example :
