qa-web	QA test skill for web applications using agent-browser. Tests forms, navigation, responsive layouts, state persistence via cookies/localStorage, and visual regression. The web counterpart to agent-device — together they cover native + web testing. Invoke when user says "test the web app", "test localhost", "QA the website", "test the form", "verify responsive layout", "run web tests", "test browser", or any task requiring automated web application testing.

qa-web

Web application QA testing using agent-browser. The web counterpart to agent-device — together they provide full coverage for apps with both native and web versions.

When to Use

Scenario	Tool
Test native iOS/Android app	agent-device + CDP
Test web app / localhost	agent-browser (this skill)
Test React Native Web	agent-browser (this skill)
Test responsive layouts	agent-browser (this skill)
Test forms and navigation	agent-browser (this skill)

Core Workflow

Every web test follows the same pattern as native tests:

1. Navigate: agent-browser open <url>
2. Snapshot: agent-browser snapshot -i (get element refs)
3. Interact: Use refs to click, fill, select
4. Re-snapshot: After navigation/DOM changes, get fresh refs
5. Assert: Verify URL, text, element state

agent-browser open http://localhost:3000/login
agent-browser snapshot -i
# Output: @e1 [input type="email"], @e2 [input type="password"], @e3 [button] "Sign In"

agent-browser fill @e1 "user@example.com"
agent-browser fill @e2 "password123"
agent-browser click @e3
agent-browser wait --load networkidle
agent-browser snapshot -i  # Check result

Configuration

Set web-specific values in qa.config.sh:

export WEB_BASE_URL="http://localhost:3000"   # Your web app URL
export WEB_SESSION="qa"                        # Browser session name
export WEB_VIEWPORT_WIDTH=1280                 # Default viewport
export WEB_VIEWPORT_HEIGHT=720

Usage

Run example web test

bash .pi/skills/qa-automation/qa-web/run.sh

Run with headed browser (see what's happening)

export WEB_HEADED=true
bash .pi/skills/qa-automation/qa-web/flows/example-web-test.sh

Helper Library — web-helpers.sh

Source this in your web test scripts for consistent patterns:

source .pi/skills/qa-automation/qa-web/lib/web-helpers.sh

Test Patterns

Form Testing

source web-helpers.sh

web_open "$WEB_BASE_URL/signup"
web_snapshot

web_fill @e1 "Jane Doe"
web_fill @e2 "jane@example.com"
web_fill @e3 "password123"
web_select @e4 "California"
web_click @e5  # Submit
web_wait --load networkidle

web_assert_url "**/dashboard"
web_assert_text "Welcome, Jane"
web_screenshot "signup-success"

Navigation Testing

web_open "$WEB_BASE_URL"
web_snapshot

# Click nav links
web_click @e3  # "About" link
web_assert_url "**/about"
web_screenshot "about-page"

# Go back
agent-browser back
web_assert_url "**/"

Responsive Testing

# Desktop
agent-browser set viewport 1440 900
web_open "$WEB_BASE_URL"
web_screenshot "desktop-home"

# Tablet
agent-browser set viewport 768 1024
web_screenshot "tablet-home"

# Mobile
agent-browser set viewport 375 812
web_screenshot "mobile-home"

State Persistence (Cookies/Storage)

# Login and save state
web_open "$WEB_BASE_URL/login"
web_fill @e1 "user@example.com"
web_fill @e2 "password"
web_click @e3
web_wait --load networkidle
web_save_state "/tmp/qa-auth-state.json"

# Reuse in future tests
web_load_state "/tmp/qa-auth-state.json"
web_open "$WEB_BASE_URL/dashboard"
web_assert_text "Welcome"  # Still logged in

Accessibility Testing

web_open "$WEB_BASE_URL"
agent-browser snapshot  # Full a11y tree
agent-browser screenshot --full /tmp/qa-full-page.png

Integration with Native Tests

For apps with both native and web versions, use both tools in the same test run:

# Test native app
bash .pi/skills/qa-automation/qa-scroll/run.sh

# Test web app
bash .pi/skills/qa-automation/qa-web/run.sh

# Both results in /tmp/qa-tests/

Troubleshooting

Problem	Solution
"agent-browser: command not found"	Install: npm install -g agent-browser
Browser launches but page is blank	Check URL and dev server: curl $WEB_BASE_URL
Refs invalidated after click	Always re-snapshot after navigation/DOM changes
Can't access localhost	agent-browser runs locally — it CAN access localhost (unlike web_remote)
Headed mode not showing	Set export WEB_HEADED=true before running
