Ensuring Visual Perfection in RoomCraft: A 3D Interactive App
Caught 15+ visual rendering and interaction bugs before the final prototype presentation through structured exploratory testing and precise bug reporting.
warningChallenge
- • Zero automated regression testing in the initial development phase
- • Tight deployment cycles with frequent UI/3D rendering inconsistencies
- • Risk of defect leakage impacting user experience in production
- • No formal test coverage for complex 3D interactions and state management

As the sole QA Manual Tester, I stepped in to bridge the gap between development and quality. With no existing test automation, I took ownership of the end-to-end quality assurance process—focusing on exploratory testing, cross-platform validation, and precise bug reporting to ensure a seamless, pixel-perfect user experience before launch.
RoomCraft's Story
RoomCraft began as an ambitious project to simplify interior design through an immersive 3D experience. Built with React, Redux, and React Three Fiber, the platform offered powerful features—from furniture placement to real-time room customization. However, ensuring visual perfection across browsers, devices, and complex 3D interactions became a critical challenge.
With a tight 1-month timeline and a small team of three — one backend developer, one frontend developer, and myself handling both QA and frontend — efficiency was critical. There was no existing test automation, so I took ownership of quality assurance while also contributing directly to the frontend codebase. By building reusable UI components, managing state with Redux Toolkit, and simultaneously prioritizing high-risk areas of the 3D canvas through focused exploratory testing, I helped the team intercept critical rendering flaws before they ever reached end-users.
Testing Strategy
To ensure RoomCraft delivered a flawless 3D design experience, I implemented a structured, user-centric QA approach.
Exploratory Testing
Simulated real-world user journeys—from furniture selection to 3D room customization—to uncover unexpected visual glitches, interaction bugs, and edge cases in high-complexity 3D scenes.
Cross-Platform Matrix
Validated visual consistency and performance across 14+ browser and device combinations, including desktop, tablet, and mobile views, ensuring the 3D environment remained responsive and stable.
Bug Documentation
Established a standardized bug reporting workflow, providing clear reproduction steps, annotated screenshots, and severity ratings to accelerate developer triage and resolution.
Key Technical Insights
Quality FocusFrontend & QA Synergy
Built reusable UI components with React and Tailwind CSS while simultaneously testing them. This dual perspective allowed me to catch UI inconsistencies early and ensure components were both functional and testable.
Visual & Interaction Focus
Developed a keen eye for visual regression—catching misaligned 3D models, texture glitches, and rotation/scaling inconsistencies that impacted user immersion.
Agile Collaboration
Worked closely with developers using an iterative feedback loop, ensuring rapid fixes and maintaining momentum during tight sprint cycles.
Visual Rendering & Interaction Bugs
Quality InsightsCaught 15+ visual rendering and interaction bugs before the final prototype presentation through structured exploratory testing and precise bug reporting.
iOS Safari WebGL Context Loss on Room Switch
Observed Behavior
3D furniture models fail to render on iOS Safari after switching rooms. Console logs "CONTEXT_LOST_WEBGL".
Resolution: Implemented a context restoration listener that automatically reinstantiates the renderer without requiring a page refresh.
Critical Crash during 3D model loading on mobile hardware
Observed Behavior
OOM crash on mid-range Android devices when loading high-density room layouts and complex furniture meshes.
Resolution: Integrated level-of-detail (LOD) streaming and aggressive texture compression for mobile-specific assets.
