ui-verify

Launch the app with WEBKIT_INSPECTOR_HTTP_SERVER set, then run node ui.mjs shot with an output path and optional CSS selector. The script connects to WebKit's remote inspector over WebSocket and writes a PNG of the viewport or a single element.

Use ui.mjs click with a CSS selector or text= prefix, and ui.mjs type for input. Typing goes through the native value setter plus an input event because React ignores a plain value assignment, and batch steps with the do command over one connection.

The screenshot was taken before the data arrived. Always wait on content that only exists after loading, such as a row count predicate, rather than shooting immediately after a navigation click.

Playwright drives Chromium, which is not the engine this Linux Tauri app ships on, and WebdriverIO needs its own build and app instance per run. The inspector approach reuses the running app with no extra processes, while WebdriverIO remains the right choice for a cross-platform CI suite.

WebKit answers awaitPromise with an empty object and wasThrown false, which is indistinguishable from a call returning nothing. The await command instead parks the promise on window and polls its state from outside.

DOM clicks prove handlers and state changes but skip hit-testing, drag regions, and the native titlebar. Relaunch with app.sh --x11 under XWayland and use xdotool and import for reachability, window dragging, and native captures.
