E2E Testing Guide

Overview

Desktop E2E tests use WebDriverIO (WDIO) to drive the Tauri app via two automation backends:

Platform	Driver	Port	App format	Selectors
Linux (CI default)	tauri-driver	4444	Debug binary	CSS / DOM
macOS (local dev)	Appium Mac2	4723	.app bundle	XPath / accessibility

Linux is the default CI path (ubuntu-22.04). macOS E2E is available for local development and as an optional CI workflow.

---

Quick start

Linux (CI default)

# Install tauri-driver (one-time)
cargo install tauri-driver

# Build the E2E app
yarn workspace openhuman-app test:e2e:build

# Run all flows
yarn workspace openhuman-app test:e2e:all:flows

# Run a single spec
bash app/scripts/e2e-run-spec.sh test/e2e/specs/smoke.spec.ts smoke

On headless Linux (CI), tests run under Xvfb for a virtual display.

macOS (local dev)

# Install Appium + Mac2 driver (one-time, needs Node 24+)
npm install -g appium
appium driver install mac2

# Build the .app bundle
yarn workspace openhuman-app test:e2e:build

# Run all flows
yarn workspace openhuman-app test:e2e:all:flows

Docker on macOS (Linux E2E locally)

Run the same Linux-based E2E stack from macOS using Docker:

# Build + run all E2E flows
docker compose -f e2e/docker-compose.yml run --rm e2e

# Build the app first (if needed)
docker compose -f e2e/docker-compose.yml run --rm e2e \
  yarn workspace openhuman-app test:e2e:build

# Run a single spec
docker compose -f e2e/docker-compose.yml run --rm e2e \
  bash app/scripts/e2e-run-spec.sh test/e2e/specs/smoke.spec.ts smoke

Requires Docker Desktop or Colima. The repo is bind-mounted so builds persist between runs.

Architecture

Platform detection

app/test/e2e/helpers/platform.ts exports:

• isTauriDriver() — true on Linux (tauri-driver session)
• isMac2() — true on macOS (Appium Mac2 session)
• supportsExecuteScript() — true when browser.execute() works (tauri-driver only)

Element helpers

app/test/e2e/helpers/element-helpers.ts provides a unified API:

Helper	Mac2 (macOS)	tauri-driver (Linux)
waitForText(text)	XPath over @label/@value/@title	XPath over DOM text content
waitForButton(text)	XCUIElementTypeButton XPath	button / [role="button"] XPath
clickText(text)	W3C pointer actions	Standard el.click()
clickNativeButton(text)	W3C pointer actions on XCUIElementTypeButton	Standard el.click() on button
clickToggle()	XCUIElementTypeSwitch / XCUIElementTypeCheckBox	[role="switch"] / input[type="checkbox"]
waitForWindowVisible()	XCUIElementTypeWindow	Window handle check
waitForWebView()	XCUIElementTypeWebView	document.readyState check
hasAppChrome()	XCUIElementTypeMenuBar	Window handle check
dumpAccessibilityTree()	Accessibility XML	HTML page source

Deep link helpers

app/test/e2e/helpers/deep-link-helpers.ts handles auth deep links:

• tauri-driver: browser.execute(window.__simulateDeepLink(url)) (primary), xdg-open (fallback)
• Appium Mac2: macos: deepLink extension command (primary), open -a ... (fallback)

Writing cross-platform specs

1. Use helpers from element-helpers.ts — never use raw XCUIElementType* selectors in specs
2. Use clickNativeButton(text) instead of inline button-clicking code
3. Use hasAppChrome() instead of checking for XCUIElementTypeMenuBar
4. Use waitForWebView() instead of checking for XCUIElementTypeWebView
5. For macOS-only tests, use process.platform guards or separate spec files

Environment variables

Variable	Default	Description
TAURI_DRIVER_PORT	4444	tauri-driver WebDriver port
APPIUM_PORT	4723	Appium server port
E2E_MOCK_PORT	18473	Mock backend server port
OPENHUMAN_WORKSPACE	(temp dir)	App workspace directory
OPENHUMAN_SERVICE_MOCK	0	Enable service mock mode
OPENHUMAN_E2E_AUTH_BYPASS	unset	Enable JWT bypass auth
DEBUG_E2E_DEEPLINK	(verbose)	Set to 0 to silence deep link logs
E2E_FORCE_CARGO_CLEAN	unset	Force cargo clean before E2E build

---

CI workflows

Default (every push/PR)

The e2e-linux job runs on ubuntu-22.04:

1. Installs system deps (webkit2gtk, Xvfb, dbus)
2. Installs tauri-driver via cargo
3. Builds the app with mock server URL baked in
4. Runs all E2E flows under Xvfb

Optional macOS E2E

The e2e-macos job runs only via manual dispatch (workflow_dispatch with run_macos_e2e: true):

1. Installs Appium + Mac2 driver
2. Builds the .app bundle
3. Runs all E2E flows

---

Troubleshooting

Linux: "WebView not ready" timeout

Ensure DISPLAY is set and Xvfb is running:

export DISPLAY=:99
Xvfb :99 -screen 0 1280x1024x24 &

Also ensure dbus is started (required by webkit2gtk):

eval $(dbus-launch --sh-syntax)

Linux: tauri-driver not found

cargo install tauri-driver

macOS: Deep links not working in tauri dev

Deep links require a .app bundle. Use yarn tauri build --debug --bundles app instead.

Docker: Build is slow on first run

The first Docker build compiles Rust + tauri-driver from source. Subsequent runs use cached layers. Cargo registry and git sources are cached via Docker volumes.

Agent-observable artifact flow

For a canonical, inspectable run that drops screenshots, page-source dumps, and mock request logs on disk:

bash app/scripts/e2e-agent-review.sh

Artifacts land in app/test/e2e/artifacts/<timestamp>-agent-review/. Full details + helper API: AGENT-OBSERVABILITY.md. Any failing test triggers wdio.conf.ts's afterTest hook, which writes failure-*.png + failure-*.source.xml into the same run dir.
