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.

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.

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.

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.

At Vela Games, we use CircleCI for building Project-V, our new multiplayer online co-op (MOCO) game that fuses the teamplay and skill of a multiplayer online battle arena (MOBA) game with the adventure of a massively multiplayer online (MMO) dungeon run.

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.

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.
