Go, often referred to as Golang, is a popular programming language built by Google. Its design and structure help you write efficient, reliable, and high-performing programs. Often used for web servers and rest APIs, Go offers the same performance as other low-level languages like C++ while also making sure the language itself is easy to understand with a good development experience.
Go’s httptest package is a useful resource for automating your server testing process to ensure that your web server or REST API works as expected. Automating server testing not only helps you test whether your code works as expected; it also reduces the time spent on testing and is especially useful for regression testing. The httptest package is also useful for testing HTTP clients that make outbound requests to remote servers.
