In this article, I’ll be describing how we handle patches across PC and mobile for TFT, and how this relates to quality assurance. Later, I’ll tag in my engineering counterpart, Gavin Jenkins, to give a super techy point of view on patches, and we’ll dive into two use cases that demonstrate different types of patches and how we deploy them.

Hi, I’m Guy Kisel, and I’m a software engineer on Legends of Runeterra’s Production Engineering: Shared Tools, Automation, and Build team (PE:STAB for short). My team is responsible for solving cross-team shared client technology issues and increasing development efficiency. In this article I’m going to share some details about how we build, test, and deploy Legends of Runeterra, a digital collectible card game. 

When VALORANT was still early in development, we had high hopes that in the future we’d launch with high initial popularity. From the beginning, we prioritized scalability to make sure we could support the number of players we were hoping for. Once VALORANT entered full production, we began working in earnest on a load test framework to prove out our tech. After many months of work, we successfully ran a load test of two million simulated players against one of our test shards, giving us the confidence we needed for a smooth launch. This article explains how we load tested our platform, and how we tackled the scaling challenges we encountered along the way. 

Hi, I'm Doug Lardo, a solutions architect at Riot Games. In this article, I'm going to introduce the concept of Fault Injection Testing, and talk about the Riot Games API and how they implemented it. Then I’ll discuss our testing methods, what we found, and soap box a little bit about high availability design along the way.

So, why do Bug Blogs? Well, at Riot, we believe that a fundamental component of the development process is understanding that failures can and do happen. We make mistakes because we’re humans, and humans are far from perfect. And that’s okay! What’s important is to recognize failures for what they are, work to understand why they happened, learn from them, and make needed changes based on those learnings. That’s how we grow and that’s how we get better.

Hi, I’m Guy Kisel, and I work on the League client update’s Test, Build, and Deploy team, here to talk about the project's automated testing.

Hi, I’m Jim ‘Anodoin’ Merrill, and I work on test automation efforts for League of Legends, focused specifically on the in-game experience. I currently serve as the tech captain to the Build Verification System Development (BVS-Dev) team. In large part, our team builds tools for automated testing and helps teams write better tests.
