Mobile Game Testing: Things to Know

As a leading outsourcing game development company, at Melior Games we understand the importance of thorough testing to ensure the success of mobile games. In this article, we’ll delve into the intricacies of mobile game testing, including its significance, different types of testing, specific techniques, challenges, and top tools for effective testing.

What is Mobile Game Testing?

Mobile game testing is an essential part of game development that involves evaluating the functionality, performance, usability, and compatibility of games across different mobile devices and platforms. The objective is to find and fix as many issues as you can because they could ruin the fun for the players. Additionally, thorough testing guarantees that the game satisfies all requirements and quality standards.

Types of Mobile Testing

Functional testing

Functional testing concentrates on confirming whether the game operates as intended, encompassing its gameplay mechanics, user interface, controls, and features. Testers assess different scenarios to pinpoint bugs associated with gameplay, navigation, and interactions with in-game elements.

Compatibility testing

Compatibility testing guarantees the game functions seamlessly across various mobile devices, operating systems (iOS, Android, etc.), screen sizes, resolutions, and hardware configurations. Testers evaluate the game’s performance across a spectrum of devices to ensure a uniform and optimal experience for all users.

Performance testing

Performance testing examines how effectively the game operates regarding responsiveness, speed, stability, and resource management. Testers track aspects such as battery life, memory usage, frame rates, and loading times to detect any issues or performance bottlenecks that could harm the gaming experience.

Usability testing

Usability testing concentrates on evaluating the game’s user interface (UI) and user experience (UX) to guarantee intuitive navigation, clear instructions, and seamless interactions. Testers collect feedback from users to pinpoint any usability problems or areas needing enhancement in terms of accessibility, readability, and overall user satisfaction.

Security testing

The effectiveness of the game’s defense against security risks such as virus attacks, illegal access, and data breaches is evaluated through security testing. Testers look over the game’s security protocols, such as data protection, authentication, and encryption, to identify and fix any flaws that can endanger user information or the integrity of the game.

Network testing

Network testing examines how well the game works in various network environments  (Wi-Fi, 3G, 4G, and 5G connections), and considers changes in network speed, capacity, and reliability. 

Localization testing

To make sure that the text, images, and music in the game are appropriately translated and culturally relevant, localization testing checks how well the game has been adapted to various languages. Testers verify user interface components, localized information, and in-game communications to guarantee a smooth and engaging experience for players across the globe

Techniques Specific for Mobile Testing

Mobile game testing involves various methods beyond traditional functional and performance testing. Two notable techniques are A/B testing and alpha-beta testing, each serving distinct purposes in ensuring the success of mobile games.

A/B Testing

A/B testing, sometimes referred to as split testing, contrasts two game versions to find out which one consumers prefer. With this method, players are split into two groups and given access to separate game versions, known as Version A and Version B. Then, depending on certain measures like player engagement, retention, monetization, or any other key performance indicators (KPIs) pertinent to the game’s goals, the performance of each version is evaluated.

By evaluating the effectiveness of various game aspects, such as user interface designs, gaming mechanics, in-game features, pricing tactics, or promotional offers, A/B testing enables developers to make data-driven decisions. Developers can improve the game’s user pleasure, retention, and revenue by experimenting with changes and tracking how they affect player behavior. They may utilize A/B testing, for instance, to compare two alternative user interface designs for the level selection screen of a mobile puzzle game. Developers can determine whether layout improves players’ overall gaming experience by examining measures like the percentage of players who finish levels, the amount of time spent on each level, or the frequency of in-app purchases.

Alpha-Beta Testing

Alpha-beta testing sometimes referred to as “beta testing” and “alpha testing”. It’s an approach to testing mobile games intended to identify and address defects before the official release.

Alpha Testing

Alpha testing marks the initial stage of evaluation wherein the game undergoes internal scrutiny by the development team or a select group of testers. This phase, conducted in a closed environment, is designed to pinpoint and rectify crucial bugs, glitches, and performance issues during the game’s early development. Testers offer feedback on various facets of the game, encompassing gameplay mechanics, user interface, stability, and overall user experience.

Throughout the alpha testing phase, developers concentrate on validating core game functionalities, evaluating game balance, and ensuring alignment with the design specifications and quality standards outlined by the development team. The insights gleaned from alpha testing aid developers in prioritizing and resolving critical issues, refining gameplay mechanics. Also it is useful for implementing necessary adjustments before advancing to subsequent testing phases.

Beta Testing

Beta testing is the subsequent phase of testing where the game is released to a larger audience of external testers or beta testers for further evaluation and feedback. This open-testing phase allows developers to gather insights from a diverse group of players with varying demographics, preferences, and devices.

Beta testers play an essential role in identifying potential usability issues, gameplay imbalances, compatibility issues across different devices and platforms, and other aspects that may impact the game’s overall quality and user experience. Developers leverage beta testing to gather valuable feedback, fine-tune game mechanics, optimize performance, and address any remaining bugs or issues reported by testers.

Developers can include comments from both internal and external testers to gradually improve the game by implementing alpha-beta testing. The mobile game that emerges from this iterative process is more polished and improved. It leads to meeting players’ expectations by the official release.

The quality, performance, and overall user experience of mobile games are all enhanced by the integration of A/B and alpha-beta testing into the development process. In the end, this helps them succeed in the highly competitive mobile game industry. At Melior Games, we understand how important it is to use a variety of testing techniques. It is necessary for producing exceptional mobile games that draw in and interact with players all over the world.

Challenges in Mobile Testing

Mobile game testing presents several challenges due to the diverse range of devices, platforms, network environments, and user preferences.

  • Device Fragmentation: The broad range of mobile devices has varying screen sizes, resolutions, and hardware specs. As a result, it is difficult to guarantee consistent performance and compatibility across all devices
  • Platform Diversity: Mobile games need to be compatible with multiple platforms, including iOS and Android. Each platform has its own set of guidelines, restrictions, and development tools. Ensuring consistency and quality across platforms requires meticulous testing and optimization.
  • Network Variability: Mobile games often rely on network connectivity for online features, multiplayer modes, and in-game purchases. Testing the game’s performance under different network conditions and addressing latency issues can be challenging, especially in regions with limited or unreliable network coverage.
  • User Experience: Delivering a seamless and immersive user experience across different devices, screen sizes, and input methods requires thorough testing of the game’s UI/UX design, controls, and interactions. Ensuring intuitive navigation and responsive gameplay is essential for player engagement and satisfaction.
