dev-env.ps1 script handles Up, Down, Status, Restart, Logs, and baseline serving at a specific commit (-At), with port-based state detection and env-var injection for gated app seams. - Environment reset and hygiene: clean-fredo-db.ps1 wipes the live SQLite DB for fresh-slate tests, and process-hygiene.ps1 lists or kills orphaned opencode/node processes that block new runs. - E2E testing methodology: Nine DOM test patterns, mandatory dual DOM-plus-screenshot verification per acceptance criterion, a regression smoke checklist, and diagnostics for known failure signatures (wedged MCP bridge, stale driver session). - Use Case: A QA agent dispatched against spec branch spec/2762 runs dev-env.ps1 -Action Up -Spec 2762, connects via tauri_driver_session start, tests each user-observable acceptance criterion with screenshots, and reports a structured pass/fail table. ## Quick Start Start the dev instance by running the dev-env script with Action Up, then connect with tauri_driver_session start and begin testing acceptance criteria with paired DOM snapshots and screenshots.High-intent search queries and answers about installing and using this skill.
Run the dev-env.ps1 script with -Action Up to auto-start the instance and poll ports 5174 and 9223 until responsive, and -Action Down to kill the process tree by port. Status, Restart, and Logs actions are also supported.
After the dev instance reports ready, connect with tauri_driver_session start, then test each acceptance criterion using tauri_webview_interact, tauri_webview_dom_snapshot, and tauri_webview_screenshot. Every criterion requires both DOM verification and visual screenshot confirmation to pass.
Run clean-fredo-db.ps1, which stops the dev instance, deletes fredo.db plus its WAL and SHM files from the app data directory, and verifies deletion. Add -Restart to bring the instance back up with a fresh schema recreated on launch.
A wedged WebSocket server blocks every MCP command path while static checks still pass, shown by a 'Handshake not finished' error in logs. Recover with a full Down then Up cycle and verify the clean 'WebSocket server listening' log line before retesting.
The window.__MCP__ helper namespace is injected once per driver session and is wiped by Vite HMR reloads or app restarts. Stop and start the driver session to re-inject it; escalate to a full Down/Up cycle only if a fresh session does not fix it.
Use dev-env.ps1 -Action Up -Spec <N> -At <pre-fix-sha> to serve the pre-fix product code from the spec branch tip without checking out main or hand-rolling a dev server. A standard Up afterward restores the tip code for the after-fix measurements.
