Players forgive many things, but not crashes, lag or unfair difficulty. Game QA covers both technical quality and the fun factor.
Two kinds of testing
- Quality assurance (QA): does the game work correctly on every device?
- Playtesting: is the game understandable, balanced and fun?
You need both, from the first prototype to live operation.
Functional testing
- Every mechanic, menu and button works as designed
- Save and load, progression and rewards are correct
- Purchases, ads and restore-purchase flows work
- Edge cases: interrupted sessions, phone calls, low storage, airplane mode
Performance testing
Mobile games must run on low-end and mid-range devices, not just the latest flagship. We profile:
- frame rate (target 30 or 60 fps, stable),
- memory usage and loading times,
- battery drain and device temperature,
- download size (smaller apps get more installs).
Compatibility testing
Different screen sizes and aspect ratios, notches, Android versions and manufacturers, iOS versions and controllers on PC.
Localisation QA
Text fits in buttons in every language, fonts support special characters (German umlauts, for example), and cultural details are correct.
Playtesting
Watch real players from the target group without helping them. Questions to answer:
- Do they understand the goal and controls without explanation?
- Where do they get stuck or quit?
- Is the difficulty curve right?
- What do they enjoy most?
Analytics from test builds show where players drop off level by level.
Soft launch
Before a global release, many mobile games launch in a few smaller markets. Real-world data on retention, monetisation and crashes guides final improvements.
Automation
Automated tests for core logic and build pipelines that run checks on every change catch regressions early, especially during live-ops.
After launch
Crash reporting, player feedback and review monitoring continue as part of live-ops. Every update goes through regression testing.
Quality is built into our production pipeline – not added at the end.
