Testing Methodology & QA Framework
Our multi-stage testing process spanning functional edge-case checks, 8-viewport responsive audits, TypeScript verification, and WASM memory safety.
"No tool is marked complete until it passes strict automated build checks, 0-error TypeScript compilation, and manual testing across 8 responsive breakpoints."
1. 8-Viewport Mobile-First Testing Matrix
Every layout is audited across 8 mandatory viewport widths to eliminate clipping, text overflow, or horizontal scrollbar bugs:
320pxMobile
360pxMobile
390pxMobile
414pxMobile
768pxTablet
1024pxLaptop
1440pxDesktop
1920pxDesktop
2. Automated Build & Type Verification
Prior to committing code, two mandatory CLI checks must pass cleanly:
- TypeScript Strict Typecheck: `npx tsc --noEmit` must return exactly **0 type errors**.
- Production SSG Prerendering: `npm run build` must successfully prerender all 62+ static page routes without broken dependencies or missing exports.
3. File Processing & WASM Memory Audits
For heavy file-processing tools (Image Compressor, PDF Compressor, Tesseract OCR, Base64 Encoder):
- Large File Testing: Audited with files up to 50MB to verify in-browser canvas and WebAssembly memory heap boundaries.
- Format & Quality Preservation: Output integrity verified to ensure zero unintended resolution scaling or color profile degradation.
- Touch Target Safety: Every interactive button, slider, and tab strictly adheres to a minimum 44x44px touch target boundary.
