Components are reusable bits of code that, most of the time, work and function independently. If you want to be confident that components are working properly, you need to test them. Conveniently, Cypress.io has designed their testing framework to include component testing. This tutorial illustrates the differences between end-to-end (E2E) and component testing, and what to consider when using these methods. Then, you will learn how to use Cypress for component testing.

Recently I started hearing more and more about developer experience, which to me was a bit new-ish, so seriously what is developer experience? Another buzz word? A real thing? It’s been a while since I actually developed code … yes yes … you can laugh … a sales person that used to be a developer 😃, and A LOT changed since then. The number of tools a developer should work with on a daily basis is just crazy.

Sleuth’s product team is pleased to announce an exciting new feature that provides early and actionable visibility into emerging work-in-progress risk! With this release, Sleuth provides customers even more actionable visibility into their engineering efficiency. It extends Sleuth's deploy-centric tracking capabilities upstream in the developer workflow to provide real-time visibility into in-flight work and its emerging risks. Here's how it works.

We can completely eliminate software vulnerabilities caused by memory corruption by moving software away from C and C++. The National Security Agency (NSA) is urging developers to shift to memory safe languages – such as C#, Go, Java, Ruby, Rust, and Swift. Could 2023 be the year of memory safety?

Earlier this year, CircleCI added GitLab as the third version control system that we support, in addition to GitHub and Bitbucket. At CircleCI, it’s vital that we meet our users where they are, and many of our users are on GitLab. We were happy to make it possible for our users to build, test, and deploy via the GitLab platform.

When it comes to building RESTful APIs, PHP’s open source Laravel framework remains a top 5 backend framework for web development. Laravel also makes testing your API endpoints a breeze by providing an easy-to-use testing suite. In this post, we will build a token-based authentication API with Laravel, write tests for the endpoints, and automate the build and testing process with CircleCI.

This article is based on conversations with Lætitia Avrot, Field CTO at EDB and David Tuite Founder of Roadie from our webinar on the Who What Where and Why of Commercial Open Source that you can watch here.

GitLab is a complete DevOps platform that enables enterprises and organizations to deliver software to markets smoothly while ensuring high product quality. Software engineering practices use many testing techniques, from unit tests to integration tests. This article helps you understand software testing with unit and integration tests. It highlights the fundamental differences between unit and integration tests and demonstrates how to write integration tests for your applications.

JavaScript Immediately Invoked Function Expressions (IIFEs) are functions that are executed when they are initialized. An IIFE (pronounced “iffy”) can be initialized or defined to achieve a certain purpose. In this tutorial, you will learn about use cases for IIFEs and the benefits of using them over traditional functions. You will also write tests for your functions and integrate CI/CD for these tests.

CircleCI notification orbs were built to deliver messages to the appropriate channels when a build is successful or when it fails. This helps everyone involved in a project stay up-to-date with the status of the latest build. In this tutorial, you will explore and implement notifications sent to a Slack channel and also sent via SMS. To accomplish this task, you will make use of the Slack and Twilio orbs from the CircleCI orb registry.

For the last few years, many development teams have replaced traditional data centers with cloud-hosted infrastructure. Cloud adoption continues to grow, and teams are updating applications to leverage cloud-based services. But for many organizations, adopting a single cloud provider to host all their applications and data can put their business at risk. To reduce these risks, some organizations are distributing resources across multiple cloud providers in a specifically designed way.

Your software development team has an enormous number of tools available to them. Some older tools are being used in new ways, which has inspired the creation of more new tools to choose from. For example, JavaScript has grown from a language used to add interactivity on websites to a full-stack language for both frontend and backend needs. JavaScript has paved the way for Express, Nest.js, and many others.

If you’re writing software today, then you likely use a CI/CD pipeline to build and test your code before deploying it to production. Having a fast and efficient build pipeline saves you development time, shortens feedback loops, and helps you ship features faster. Conversely, slow and unreliable build pipelines are full of lost productivity and sadness.

Package promotion workflows are a great way to isolate and protect production repositories away from pubic upstreams, so they only receive clear and vetted packages.

Development operations (DevOps) combines best practices, cultural transformation, and tools to improve your organization’s software development and delivery velocity. Teams can employ DevOps regardless of an organization’s size and continuously deliver new software features, updates, and patches to enhance software quality and customer experiences.

The Serverless framework is an open-source framework written in Node.js that simplifies the development and deployment of AWS Lambda functions. It frees you from worrying about how to package and deploy the application to the cloud, so you can focus on your application logic. Serverless applications are distributed by design, so good code coverage is vital, and should include unit testing.

Software development and the DevOps lifecycle now requires continuous integration and delivery, also referred to as CI/CD. To help users automate the steps between a developer checking in code and releasing that code into production, open source CI/CD solutions are created.

As you might be aware, each team has its own unique workflow based on the project type, size of the company, team preferences, and a number of other factors. The larger the team, the more difficult it is to keep things under control: disputes become more regular, delivery deadlines may postpone, priorities always change - the list may go on and on. Adapting Git is the first step in resolving these challenges, as it can be used in almost any workflow.
