Understanding the evolution of modern game testing
Today, QA is one of the key components of any modern software development process. It is unimaginable to release software to users without testing it first. Users now have so many choices with regard to apps, games, and digital tools, and if you release software that does not work properly or has usability issues, you risk losing many of your users. Even worse, you risk your reputation as a developer if players discover something in your game that doesn’t work and publish this information online on game forums and social media.
Therefore, QA is an important component of the development process.
QA and testing are interchangeable terms. Throughout history, humans have striven to provide quality of execution in their work – from the ancient pyramids through medieval fortresses to modern software. At its core, modern QA has its roots in medieval professional guilds, such as those for tailors, merchants, and smiths. To ensure that the quality of their products met the required quality standards, guilds implemented strict peer control that in many ways is similar to testing today. They set quality standards that guild members had to meet in order to become part of and stay in the guild. These parameters ensured that guild members everywhere provided a high level of service and in return, drove more business to them.
Modern testing is not too far from that: we test software to ensure that it meets the required quality standards and includes all implemented and approved features. Of course, these days, we have replaced the quality standards set by guilds with ones set by product owners and end users.
Modern game testing has developed along with the growth of the gaming industry. Games became widely popular in the 1980s, and they kept on evolving to various new platforms: first consoles, then home PCs, and, in the 21st century, mobile and other handheld devices. It doesn’t look like the industry is going to slow down anytime soon either. The gaming industry in 2021 was globally worth more than 180 billion USD, more than the music, TV, and film industries put together (https://www.thc-pod.com/episode/the-gaming-industry-is-now-bigger-than-movies-and-music-combined). The biggest money makers are mobile and free-to-play (F2P) games, and the top earners among them bring in over a billion USD per year (https://newzoo.com/key-numbers; https://www.statista.com/statistics/263988/top-grossing-mobile-ios-gaming-apps-ranked-by-daily-revenue/).
Games are a big business today and quality is more important than ever. With that said, there are no common standards for game QA across the industry. Every gaming studio is different and even within the same company, different teams follow different QA practices. The differences are even more significant when testing for different gaming platforms – while testing on consoles hasn’t changed too much since the beginning of game development, mobile game testing is embracing the latest trends in QA to be able to support more fast-paced development.
The terminology used in game testing is not unified (a particular term may mean completely different things in different studios), and even QA jobs might have different levels of responsibilities or completely different job descriptions from studio to studio. Taking into account all those differences, certain things remain the same. Testers generally spend months testing games repeatedly, using different approaches and shifting focus to different parts and characteristics of the game.
What would we consider to be QA today? There are many different definitions out there, but at its core, game QA is a set of testing activities, including test execution, exploration, and verification, that aims to ensure that games meet design specifications, technical quality, platform regulations, and player expectations. As we can see just from the definition, QA in gaming entails a lot of responsibilities and requires a whole range of skills. A game tester is a person who must fully understand the product’s vision, is familiar with technical risks and dependencies, can juggle conflicting priorities, knows the game better than anybody, and represents the players’ interests.
Now that you have a basic understanding of the prerequisites and best practices of QA for games, let us try and understand what makes game QA different from normal software testing. Knowledge of these differences, especially in terms of the unique aspects we test for in game development, is essential for us to master QA testing and meet the end user’s expectations within the gaming industry.
