Mobile Game Testing: Challenges, Best Practices, and Emerging Trends

Game testing is complex and different from other types of testing. There is a need for live user testing, alpha, and beta testing, but these are only a few pieces of a broader equation. Game testing also differs from standard app testing in terms of user engagement and experience. While performing gaming app testing, QA teams must consider the fact that the success of the gaming application is contingent on the duration of time gamers spend interacting with it. It indicates that the app successfully provides users with an engaging gaming experience. 

This article highlights the challenges, best practices, and emerging trends for testing mobile game applications to deliver a superior gaming experience.

Challenges in game app testing

Challenges unique to game development and QA include device diversity, hardware configurations, AR and VR environments, OEM/carrier customizations, and various operating system versions. Considering user engagement for a longer time, factors like measuring device metrics, CPU, battery usage, overheating, social media integrations for multiplayer functionalities, AR and VR features come into play.

These factors increase the complexity of QA and lead to longer development cycles (time-to-market), higher field crash rates, higher customer support costs (more customer complaints), and an inefficient development team (dealing with customer issues vs. developing new features). 

Thus, the quality of gaming applications would be substantially impacted if testing is based solely on playing the game to detect flaws. It must be performed on a comprehensive game testing platform trusted by key industry players.

Best Practices of Mobile Game App Testing

Here is a compilation of types of testing that should be incorporated as best practices while performing game application testing:

• Fun factor testing
• AI testing
• Game level testing
• Multiplayer testing
• Audio testing
• Cross-device performance testing 
• Localization testing
• Modification API testing

‍Fun Factor Testing

Usability or user experience testing is performed on all software. However, fun factor testing is specific to games as an entertainment product. In addition to intuitive functionality, games must also be enjoyable to play. Initially, development teams need to determine whether any concept for a game is enjoyable and it would attract the intended audience. It takes a unique understanding of game design and a plethora of information and data about the target audience and what they enjoy.

AI Testing

With the increasing complexity of user behavior, testing computer-controlled opponents and artificial intelligence for intended behaviors can become exceedingly challenging. Social games like chess are a good example. Such testing requires the tester to comprehend what triggers various types of behavior and how these triggers can be confused by multiple parameters. Expertise in AI and game design must be implemented to deliver a flawless game app experience.

Game Level Testing

The level or game world testing can be one of the most complex components of game testing, especially if it is a sprawling 3D game environment, as in modern MMOs. Some of this can be automated in unique and exciting ways exclusive to game testing. It includes bots moving randomly across the game world to see if they become trapped or discovering other bugs. As the complexity of the activity increases, finding ways to simplify it with the aid of tools becomes increasingly vital.

For puzzle games, it is crucial to ensure that the graphics for each level look attractive and that each level is also passable. It is also critical to review that the game mechanics have been tested in isolation function in the different level implementations.

Multiplayer Testing

Multiplayer testing is an entirely different segment. Multiple players engage simultaneously with the game world, game servers, computer-controlled opponents, and each other. With so many possible adverse outcomes, this typically takes an entire team of testers. Numerous risk-based decisions must be made if QA teams do not wish to spend indefinite time evaluating various scenarios. For this form of testing, it is essential to understand multiplayer game design and how to test efficiently as a team.

Audio Testing

Games have distinctive characteristics when it comes to audio testing. QA teams must test that the music in a video game must immerse the player and enhance the gameplay. The audio should not only play without stuttering or missing pieces but also contribute to the gameplay. It takes substantial audio expertise and specific game audio knowledge, particularly domain expertise.

Cross-device performance testing 

Despite having the most innovative narrative, the best gameplay mechanics, and the most captivating characters, players will not enjoy your game if it is difficult to load. 

You may determine how your game performs on the most powerful graphics processing unit or GPU currently available by testing it on a powerful smartphone. Then, QA teams must test the game on mid-range and low-range devices to determine how the graphics degrade and how the game operates on cheap or older smartphones.

Localization testing

When developers upload a game to the Google Play Store or the Apple App Store, they are exposing it to more than just the local audience. Therefore, testers must identify any localization issues. 

• One potential localization issue is that of advertisements on the gaming application. Development teams must review if they target a specific market or demographic. They may wish to display different advertisements in several locations or nations according to geography to maximize the chances of generating substantial advertising revenue in such scenarios.

• Language is an additional localization consideration, as not all potential users of the gaming application will speak English. Rather than limiting the game to an English-speaking audience, the production team may decide to translate the game's menus and subtitles for conversations.
