Component testing vs unit testing

Testing is a vital part of the software development lifecycle. It plays an important role in the continuous integration/continuous deployment (CI/CD) pipeline, enabling developers to release dependable, resilient, and secure software consistently. There are many types of testing and testing methodologies: end-to-end testing, dynamic testing, integration testing, and others. This article focuses on component testing and unit testing.

CI/CD for Unity game development with GameCI's Unity orb

We recently partnered with GameCI to bridge the gap between CircleCI and the game development scene. This partnership brought forth the Unity orb, a reusable component of config you can plug into your CircleCI configuration file to build and test your Unity projects. For a while now, continuous integration and delivery have been part of the software development cookbook of several software houses and IT departments. However, this is often not the case in game development.

Beyond API testing with Jest

Jest is a JavaScript-based testing framework that lets you test both front-end and back-end applications. Jest is great for validation because it comes bundled with tools that make writing tests more manageable. While Jest is most often used for simple API testing scenarios and assertions, it can also be used for testing complex data structures. In this tutorial, we will go through how to use Jest to test nested API responses and hopefully have fun in the process.

Chaos testing: Reliability for cloud-native apps

Reliability is a critical concern for software delivery teams. Every second of lackluster performance or service interruption comes with high costs. The consequences can extend beyond just monetary expenses and have a huge impact on a company’s reputation. In a survey conducted in 2022, participants reported that over 60% of digital infrastructure failures resulted in losses of $100,000 or more.

Automate deployment of a Vue.js application to Firebase

A quick search of the internet will reveal many services available for freely hosting single page applications or static sites. Firebase is one of these services. Firebase is a development platform developed by Google that provides file storage, hosting, database, authentication, and analytics. It is free, provides an SSL certificate by default, and offers impressive speed across multiple regions. I have chosen Firebase for hosting our demo application in this tutorial.

Polyglot persistence vs multi-model databases for microservices

Microservice architecture is an application system design pattern in which an entire business application is composed of individual functional scoped services, which can scale on demand. Each team focuses on an individual service and builds it according to their skillset or language of choice. In addition to flexibility, this pattern provides: These features have made microservices architecture a popular choice for enterprises.

Speed up XCUITest execution with parallelism and test splitting

In this article, I’ll show you how to reduce the execution time of XCUITest (UI tests on iOS simulators) by splitting and running them in parallel. Automated tests and CI/CD platforms like CircleCI are necessary for iOS application development. It is important not only to introduce them once but to improve them continuously. When application code grows and automated tests increase, the execution time of build and test in CI/CD gets longer.

Introducing the CircleCI Config SDK

We are excited to announce the new CircleCI Config SDK is now available as an open-source TypeScript library. Developers can now write and manage their CircleCI config.yml files using TypeScript and JavaScript. For developers used to the ecosystem and flexibility of a full-fledged programming language, sometimes YAML can feel limiting or intimidating. With the Config SDK you can define and generate your YAML config from type-safe and annotated JavaScript.

Canary vs blue-green deployment to reduce enterprise downtime

Even before the cloud, no one liked deployment downtime. With applications hosted in traditional data centers that restricted access for local users, many organizations scheduled deployments when users were less likely to be using the applications, like the middle of the night. With widespread adoption of cloud-based, 24x7 environments available from all time zones, every hour of the day, easy-to-find deployment windows are gone.
