How We Tested iOS 12 Beta
Article Summary
Kateryna Sprynsian from Bumble's QA team shares a hard truth: when iOS 12 dropped, 60% of their users updated within weeks. Were they ready?
The Bumble/Badoo QA team walks through their complete iOS beta testing strategy, from deciding when to start (beta 6, not beta 1) to the specific bugs they caught before millions of users were affected. This is their manual testing playbook for major OS releases.
Key Takeaways
- Started testing at beta 6: early betas too unstable, most Apple bugs fixed by then
- Tested with both old Xcode 9 and new Xcode 10 builds (different bugs appear)
- Found crashes on launch, freezes with third party accounts, broken notification layouts
- CPU, memory, and battery usage showed no significant impact between iOS 11 and 12
- User adoption jumped from 1% in August to 60% by October (previous year data)
Critical Insight
Testing iOS betas caught critical crashes and UI bugs before 60% of users upgraded in just two months, protecting millions from a broken app experience.
