Slate Browser Testing Framework Research Plan

Goal

Research the best future testing framework shape for editor work by mining the local comparison repos, then document the recommended architecture under a new slate-browser doc area inside docs/.

Research Axes

1. speed
2. coverage breadth
3. IME/composition realism
4. deterministic DOM/unit harnesses
5. performance benchmarking hooks
6. agent-native parity for actions beyond Playwright primitives

Candidate Lenses

• ProseMirror
• Lexical
• Tiptap
• Slate
• edix
• use-editable
• rich-textarea
• markdown-editor
• VS Code / LSP only if they contribute testing architecture ideas

Expected Output

• one initial research document under docs/slate-browser/
• explicit recommended framework layers
• recommendation for which existing frameworks to build on
• explicit agent-native testing lane
• phased adoption path
