When we started WSO2 in 2005, there was no question what programming language was right for developing server-side enterprise infrastructure: Java. However, as we go past our 20th year and look ahead at the next 10 to 20 years, it’s clear that we need to reflect on the way forward.

Go is an incredibly useful programming language, but not all that popular among web developers. Most other languages that are used for web development have dominant frameworks - Ruby has Rails, PHP has Laravel, Python has Django, and so on. Golang web frameworks for web development are a bit more fractured with several competing (and in some cases complementary) options.

Ruby and Rails are great tools that allow you to create complex web applications quickly. Well, some kinds of complex web applications. While they excel at traditional, monolithic, server-rendered applications, they fail to excel at delivering real-time or distributed services. This is why it's so handy for Rubyists to learn a programming language like Go. Go is designed to write lightweight services that handle lots of inbound connections.

Logs play a vital role in understanding how applications and systems perform, but unstructured log data can be hard to analyse. The Grok parser helps by converting raw logs into structured, readable formats. It is widely used for extracting information such as timestamps, error codes, and IP addresses from logs, making them easier to analyse and query.

What do good tests look like, and do you even need a Golang testing framework? It’s a loaded question with an open answer. Not only do tests help ensure that your code will work as intended, but good tests can also serve as documentation for your codebase, making it easier to update and maintain in the future, while accelerating and streamlining your software development process. In this article, we outline 6 Golang testing frameworks for every type of test.

All but the simplest applications borrow code. You could write everything yourself from just core language features but who has time for that? Instead you take on dependencies, pieces of code written by others that usually give us 80% or more of what we need with 20% of the effort. Sometimes these dependencies are made to interact with a specific technology like a database, or perhaps it’s just a library providing some feature that would be onerous to write yourself.

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.

Although GoMock is one of the most popular ways to create mocks in Golang, it’s important to understand the broader landscape of mocking methods in the language to fully leverage its potential value in testing. Mocking is a powerful technique that allows developers to isolate their code, improve test reliability, and ultimately enhance overall code quality.

Go is an open-source programming language and developer environment from Google that allows for incredibly efficient and powerful applications. Go’s expressive syntax enables developers to write clean, efficient, concise code, allowing faster development cycles and easier maintenance. Whether you’re developing complex distributed systems or lightweight microservices, Go and its powerful libraries provide the tools necessary to create robust and scalable solutions.

When you run your Go programs or integration tests, numbers of raw coverage files are typically generated and dumped into a directory specified by the GOCOVERDIR environment variable. These files contain valuable data about which parts of your code were executed during tests, offering a glimpse into your code’s effectiveness and robustness. However, sifting through these raw files to extract actionable insights can be daunting and unclear for many developers.
