Challenges faced by game testers

  • Direct screen access

Most mobile games utilize direct screen access, which is performed by bypassing the OS-level tasks with the help of the various APIs and software frameworks like OpenGL and ActiveX. As a result, the conventional frameworks for mobile automated testing become redundant when mobile games are concerned. The automation only makes use of XY clicks as there is no access to the object-level data.

  • Social media integration

Mobile games are connected to social media platforms more than ever today. This urges the game testers to pay more attention as social media can be both constructive and destructive. If implemented and used effectively, social media can help connect like-minded gamers, drive exchanging ideas, and enrich the user experience. Similarly, social media integration can bring negative consequences as well. Hence, testers need to be cautious while performing social media integration.

  • Multiplayer feature and multiple locations

Testing for the multiplayer feature can be a significant challenge for the testers, especially when players are in very different locations and far apart from each other. Mobile games with multiplayer features are often difficult to test and debug and can also consist of problems that are difficult to fix. To resolve this challenge, the game testers need to check mobile games for their robust design. 

  • Game engines

Choosing the best engine for a game is no doubt a challenge for the developers, but it is often more difficult for QA to be prepared to test any range of engines they are given. They have to consider all the specifics of each engine and seamlessly apply different types of game testing to check it thoroughly.

  • The performance of gaming apps matters more than any other app

Performance is one of the key drivers of user experience, and real performance can only be monitored for using real hardware. Frame rates also act as an important factor with the richness and diversity of mobile devices where every new model counts. Further, most games utilize sensors or other hardware features which are not consistent from one device to another. If this is left unchecked, it causes several negative effects on the overall performance. 

  • Diverse tools used for game testing

The range of tools, techniques, best practices, and frameworks leveraged for mobile game testing are very extensive. But certain aspects are always executed in the same way by the developers. Despite different game engines, more than 90 percent of game developers utilize some form of image recognition. This enables testing to be as easy as capturing a screenshot and analyzing it automatically or manually. It can also be completely gameplay where the game is driven by test scripts and output is logged for further inspection.

Difference between game testing and software testing

Though game testing and software testing may be fundamentally similar as they involve testing code to deliver high-quality, working software, there are a number of significant differences in both.

Unlike game testing, software testing uses automation scripts developed pre and post-production of test cases. For setting up automation scripts, testers utilize many tools and frameworks in the software testing process.

Unlike software testing, there are a wide number of areas in game testing, especially in the case of mobile game testing that require more focus. Some of these aspects are:

Graphic performance

  • Graphics are a crucial factor in engaging the users to a particular game. Gamers usually love being involved in high graphics supported by the device and accompanied by the gaming engine. In fact, today, no game can thrive in the market without being graphically excellent. The performance metrics aren't a single parameter in this case but a collection of many that every player keeps in mind. For instance, battery drain rate—if a mobile game is causing battery drain at an unusual rate, players opt-out of such games.
  • Another factor is the GPU of the mobile phone that is used most. The GPU might be running at the highest clock rate, and hence if it isn't implemented appropriately, the game can slow down the device due to excessive heating. Hence the testers should test the games on multiple devices before zeroing on the supported devices.
  • Additionally, game testers must run the game on different devices and log vital device parameters like CPU consumption, device temperature, GPU consumption, data consumption, GPU consumption, and much more.

Very often, specific frameworks are required for functional testing. Several elements of the game design and behavior need to be tested manually as automation is not the most suitable option. Even if it is deployed, it needs substantial effort and test automation tools to generate the test scripts because game test use cases are usually beyond the simplicity of searching static elements on the screen. 

Usually, it requires you to embed an agent into the test script for identifying objects and testing if specific actions are triggered within a game. These factors add complexities to game testing as compared to software testing.

  • In the case of software testing, we require qualified professionals with Software Development Engineer in Test (SDET) certification. However, for game testing, there is no specific requirement for formal qualifications. While, in most cases, niche specialists execute the tests, gaming enthusiasts are often called to test new games.
  • Software testing focuses primarily on UI/UX, functionality, security, and system, while game testing focuses on realism, AI, and multiplayer.
