QA Challenges in Game Development

Developing modern games is a complex undertaking. Whether it's AAA titles for PC/console or mobile games for the mass market, quality assurance (QA) faces major challenges. Diverse hardware platforms, operating systems, and end devices require extensive testing, but internal QA teams often reach their limits here. Mobile gaming in particular is extremely fragmented: developers must ensure that their app runs smoothly on thousands of different devices with a wide variety of configurations. This is almost impossible to achieve with their own test devices and limited staff. In addition, internal testers can become blind to problems at some point – they lack fresh perspectives. This is where crowdtesting comes in: a globally distributed pool of testers checks the game under real conditions. In this article, we look at the practical implementation of crowdtesting in the gaming sector and the advantages it offers over purely internal QA and classic beta testing. We also show how professional services such as msg.passbrains support developers in this step.

Overcoming the Limitations of Internal QA Teams

Internal quality assurance teams do valuable work, but quickly reach their limits in practice. Staff capacities are limited—a dozen QA testers can only cover a certain number of scenarios and devices. The equipment available in the test lab is often just as limited. Although it is possible to purchase common consoles or a few dozen smartphones, the diversity of real-world usage environments remains unmatched. A test under laboratory conditions rarely reflects everything that happens out there with the players. A person from QA engineering summed it up aptly: “Crowdtesting covers real-life scenarios that we cannot replicate in the lab.” In addition, internal testers may unconsciously make assumptions due to their proximity to the product, whereas external testers approach the software with a more unbiased perspective and thus discover different bugs or usability issues that internal teams overlook. In short, internal QA remains important, but to truly cover all bases and end devices, external support is needed.

How does crowdtesting work in gaming?

Crowdtesting means that a large number of external testers check a product – in the case of games, these are real players who play on their own devices and systematically search for errors or perform defined test tasks. Professional crowdtesting platforms such as msg.passbrains have an international community of testers from which suitable candidates are selected based on the project requirements. The testers register via the platform, receive access to a pre-release version of the game (often under NDA), and complete specific test cases or exploratory gaming sessions. In doing so, they document bugs, glitches, performance issues, or UX improvement suggestions. At the end, the crowdtesting provider consolidates the results and delivers a detailed report with all findings and reproduction steps to the development team. Crowdtesting runs are usually short and focused – often only a few days per cycle – and can be repeated at any time if necessary. This agility makes it possible to achieve a rapid boost in quality even with tight release schedules. It is important to emphasize that crowdtesting is not a beta test in the traditional sense, but rather a structured testing procedure. The testers act professionally (for pay) and deliver high-quality reports instead of just providing casual feedback.

Advantages of Crowdtesting: Scalability, Diversity, Realism

Why is crowdtesting a game changer for QA? Here are the key benefits at a glance:

High Scalability: Do you need 5 testers or 500? Crowdtesting can be scaled flexibly. Large communities make it possible to deploy many testers simultaneously within a very short time—for example, to perform load tests with real users or a large regression test overnight. This scalability would only be achievable internally with disproportionate effort.

Mastering Device Diversity and Fragmentation: As mentioned, there are countless device and OS combinations in the Android ecosystem alone. Crowdtesting opens up a wide range of real devices. “The broad coverage of different devices and OS versions by crowd testers has helped us enormously in ensuring the quality of our new Android game,” reports a passbrains customer. Instead of testing theoretically in emulators, real users test on real hardware – from high-end PCs to older mid-range smartphones.

Real User Experience: Crowd testers act like normal players in their usual environment – with different network conditions, peripheral devices, playing styles, etc. This reveals practical problems that would not be obvious in a sterile test lab. For example, rare edge cases are found: a bug that only occurs when playing a certain character in a certain language setting may only come to light thanks to the diversity of the crowd. The external perspective also provides fresh usability feedback. An experienced QA manager sums it up: “Crowd testers do things that internal testers would never think of – and that's exactly what makes them so valuable.”

Quick Results: Thanks to the globally distributed community, tests can run virtually around the clock. While the in-house team sleeps, crowd testers in other time zones are already testing the latest build. This significantly reduces turnaround time. Within a few days, crowd testing provides actionable feedback so developers can respond immediately with fixes.

Cost-benefit Efficiency: Instead of maintaining a large internal testing team and equipment pool on a permanent basis, crowdtesting allows you to use resources on demand. You pay for tests that are performed, not for idle time. Many companies find that this flexibility saves costs while still achieving high test coverage. In addition, every vulnerability that is found and fixed early on prevents potentially expensive patching marathons after release.

Overcoming Challenges in Mobile Gaming

One area where crowdtesting really shines is mobile gaming. The aforementioned device fragmentation among smartphones and tablets means that without crowdsourcing, it is hardly realistic to test how an app runs on all the different displays, chipsets, OS versions, and network configurations. However, fragmentation affects not only hardware but also user habits: mobile gamers play on the go with variable internet connections, use different input devices, or multitask with other apps. Internal tests cover only a fraction of this diversity. Crowdtesting, on the other hand, recruits testers from the real world – for example, students with older Android phones who play on the bus, or iOS users with the latest iOS beta. This shows whether the game remains stable even under less than optimal conditions. Especially with free-to-play mobile games, where the competition is just a download away, smooth functionality on as many devices as possible determines success or failure. Crowdtesting allows problems such as performance drops on certain models or display errors on exotic screen formats to be found and corrected at an early stage. This gives developers the certainty that their game is ready for the market across the board.

Professional Addition to Alpha and Beta Tests

Many studios already conduct alpha and beta testing with selected groups of players. So why do they need crowdtesting as well? The answer lies in professionalism and coverage. Internal alpha testing usually involves employees or friends of the team—but they often know the game too well to be unbiased. Public beta tests, on the other hand, provide a wealth of feedback from enthusiastic fans, but this feedback is often unstructured: many players either report the same obvious bugs over and over again or report nothing at all because they just want to enjoy the game. Crowdtesting closes this gap. It is the professional complement: crowd testers are not random end users, but specifically selected, experienced testers who work under guidance. They follow test plans, try out unusual interactions, and document their results precisely. This provides the development team with high-quality bug reports that can be fed into the development process immediately. In addition, crowdtesting can be scheduled flexibly – for example, after internal QA has been completed but before the big open beta test, in order to eliminate any final showstoppers. A member of the QA management team describes the added value as follows: “Crowdtesting provides us with additional assurance of software quality and valuable usability feedback after in-house testing.” The combination of internal QA, beta community, and professional crowdtesting ultimately results in the comprehensive testing strategy that a modern game deserves.
