Argent Test UI Flow

Platform-agnostic

Physical iPhone (kind: "device"): read argent-ios-device-interact first. launch-app before anything; describe fails while the app is backgrounded.

The interaction tool names are identical on iOS and Android — gesture-tap, gesture-swipe, describe, screenshot, launch-app, etc. — and the tool-server auto-dispatches based on the udid you pass (UUID-shape → iOS, adb serial → Android).

Before testing, resolve which device to test on. Call list-devices and follow <device_selection_rule>: prefer a running device on any platform;

Once a platform is chosen, the per-platform setup skill takes over:

1. Workflow

All interactions go through argent MCP tools. Ensure the simulator/emulator is ready before starting.

For implementation tasks that modify visible UI, this workflow can also serve as a visual acceptance path.

1. Baseline screenshot: Call screenshot to see the current UI state. For visual regression comparison or UI change verification, capture the baseline at scale: 1.0 with includeImageInContext: false and keep the returned path before editing whenever feasible.
2. Find target: Before tapping, use a discovery tool to get element coordinates:
   • React Native apps: use debugger-component-tree — it returns component names with (tap: x,y) coordinates. This is the preferred tool for RN apps on either platform. To use it, resolve the argent-react-native-app-workflow skill for setup; on Android you must also run adb -s <serial> reverse tcp:8081 tcp:8081 so Metro is reachable from the device.
   • Standard app screens and in-app modals: use describe. On iOS this returns the AX tree (falls back to native-devtools when AX is empty); on Android it returns the uiautomator tree in the same DescribeNode shape.
   • Permission prompts / system modal overlays: try describe first. Fall back to screenshot only if the overlay is not exposed reliably. When the app raises its own permission dialog, answer it here — that's the real flow under test. To take a prompt out of the flow (pre-grant/deny before launch, re-enable a permission the user already denied, or reset it so the dialog reappears), use the argent-settings-permissions skill during setup instead of interacting with the dialog.
   • Fallback: use screenshot to estimate where the desired component is, then verify immediately after the action.
3. Interact: Perform the action (gesture-tap, gesture-swipe, keyboard, button, ...) — you receive a screenshot automatically.
4. Verify: Check the returned screenshot for expected results. If it shows a loading/transitional state, prefer blocking until it settles with await-ui-element (expected element visible, or a spinner hidden) over a guessed delay — but only with a selector you can trust (text/identifier/role) that the screen is known to have or that you saw in a prior describe; a guessed one just times out. Otherwise use a short fixed wait. Pick evidence by what's being asserted:
   • Visual (layout, spacing, color, typography, image/icon rendering, clipping, overflow, text rendering): prefer screenshot-diff against the baseline captured in step 1 — it surfaces pixel-visible changes the auto-screenshot might miss. Fall back to visual inspection of the auto-screenshot only when a stable baseline isn't available.
   • Structural (navigation state, element existence, accessibility labels/values, selection, hierarchy, route): verify with describe, debugger-component-tree, or native-describe-screen.
   • Runtime / log / network (console errors, API calls, persistence, timing): verify with view-network-logs, debugger-log-registry, debugger-evaluate, or targeted tests. Note debugger-log-registry returns { status: "not_connected", reason, guidance } with no log file when the debugger is unreachable — that is not evidence about the app; follow its guidance to reconnect, then re-verify.
   • Mixed: collect evidence for each relevant class.
   • Report the combined verdict: expected behavior, observed behavior, evidence used, and any blocker for requested visual diffing.
5. Repeat for each step in the flow.

2. Template

Goal: Test [feature name]

Steps:
1. Classify expected result: visual / structural / runtime-log-network / mixed → choose evidence
2. [Navigate / tap / type to reach stable comparable starting point] → verify auto-screenshot
3. screenshot { scale: 1.0, includeImageInContext: false } → save baseline path when visual or mixed evidence needs diffing
4. [Perform the action to test] → verify auto-screenshot
5. Use screenshot-diff when requested or when comparable images add useful visual evidence
6. Report: pass / fail with combined visual, structural, runtime/log/network evidence as applicable
