QA Element Extraction

QA Element Extraction Skill

Capture targeted screenshots of UI elements referenced in test procedures to create visual documentation.

Purpose

When a test step says "Click the Login button", capture a screenshot of that specific button so testers know exactly what to look for. This creates a visual glossary alongside full-page screenshots.

Element Screenshot Directory

qa-tests/
├── active/
│   └── QA-20250105-001-login.md        # QA test document
└── screenshots/
    └── QA-20250105-001/                 # Matches test-id
        ├── 01-initial-state.png         # Full page screenshots

        └── elements/                     # Extracted UI elements
            ├── login-button.png
            ├── email-field.png
            └── password-field.png

Note: The {test-id} folder name (e.g., QA-20250105-001) matches the QA test document filename.

Element Extraction Process

Step 1: Parse Test Procedure

Identify actionable elements from test steps:

Step 2: Element Identification Patterns

Look for these patterns in test steps:

Action + "the" + [Element Name] + element type

Action verbs to scan:

• Click, Tap, Press
• Enter, Type, Input
• Select, Choose, Pick
• Check, Uncheck, Toggle
• Hover, Focus
• Drag, Drop
• Scroll to

Element type keywords:

• button, btn, link
• field, input, textbox
• dropdown, select, combobox
• checkbox, radio, toggle
• icon, image, logo
• menu, nav, tab
• modal, dialog, popup
• card, tile, panel

Step 3: Capture Element

Using Playwright MCP:

// Find element by accessible name or text
const element = page.getByRole('button', { name: 'Login' });

// Capture just this element
await element.screenshot({
  path: 'qa-tests/screenshots/QA-20250105-001/elements/login-button.png'
});

Capture States

For interactive elements, capture multiple states:

elements/
├── login-button.png           # Default state
├── login-button-hover.png     # Hover state
├── login-button-focus.png     # Focus state
├── login-button-disabled.png  # Disabled state (if applicable)

Element Reference Table

Generate a reference table in the test procedure:

## Element Visual Reference

| Element | Screenshot | Selector | Notes |
|---------|------------|----------|-------|
| Login button | ![](./elements/login-button.png) | `button[name="login"]` | Blue primary button |
| Email field | ![](./elements/email-field.png) | `input#email` | With placeholder |
| Remember me | ![](./elements/remember-checkbox.png) | `input#remember` | Unchecked by default |

Playwright Commands for Extraction

By Role and Name

// Button
const loginBtn = page.getByRole('button', { name: 'Login' });
await loginBtn.screenshot({ path: 'elements/login-button.png' });

// Link
const helpLink = page.getByRole('link', { name: 'Help' });
await helpLink.screenshot({ path: 'elements/help-link.png' });

// Input field
const emailInput = page.getByLabel('Email');
await emailInput.screenshot({ path: 'elements/email-field.png' });

By Text Content

// Element containing specific text
const submitBtn = page.getByText('Submit', { exact: true });
await submitBtn.screenshot({ path: 'elements/submit-button.png' });

By Test ID

// Using data-testid attribute
const navMenu = page.getByTestId('main-navigation');
await navMenu.screenshot({ path: 'elements/main-nav.png' });

With Padding/Context

// Capture parent for context
const field = page.locator('.form-group:has(#email)');
await field.screenshot({ path: 'elements/email-field-with-label.png' });

Element Naming Convention

{element-name}[-{state}][-{variant}].png

Examples

Extraction from Test Steps

Input Format

### TC-001: User Login

| Step | Action | Expected Result |
|------|--------|-----------------|
| 1 | Navigate to login page | Login form displays |
| 2 | Enter "test@example.com" in **Email field** | Email accepted |
| 3 | Enter "password123" in **Password field** | Password masked |
| 4 | Click **Login button** | Redirects to dashboard |

Output: Element Extraction List

## Elements to Capture

From TC-001:
- [ ] Email field (`input[type="email"]`)
- [ ] Password field (`input[type="password"]`)
- [ ] Login button (`button[type="submit"]`)

Capture command:
1. Navigate to login page
2. Take element screenshots before any interaction

Glossary Building

Create a reusable element glossary for the application:

elements-glossary/
├── buttons/
│   ├── primary-button.png
│   ├── secondary-button.png
│   ├── danger-button.png
│   └── icon-button.png
├── forms/
│   ├── text-input.png
│   ├── text-input-error.png
│   ├── select-dropdown.png
│   ├── checkbox.png
│   └── radio-button.png
├── navigation/
│   ├── main-nav.png
│   ├── breadcrumb.png
│   └── sidebar-menu.png
└── feedback/
    ├── success-toast.png
    ├── error-alert.png
    └── loading-spinner.png

Integration with Test Documentation

Inline Element References

#### Step 2: Enter credentials

Enter your email in the Email field:

![Email field](./elements/email-field.png)

Then enter your password in the Password field:

![Password field](./elements/password-field.png)

Element Annotation

When extracting, note identifying characteristics:

| Element | Visual | Identification Tips |
|---------|--------|---------------------|
| Login button | ![](./elements/login-button.png) | Blue button, right side of form, text "Log In" |
| Forgot password | ![](./elements/forgot-password-link.png) | Gray link below password field |

Automated Extraction Workflow

When creating a new QA test:

1. Parse test steps for element references (bold text, quoted names)
2. Navigate to test URL using Playwright
3. Locate each element using accessibility tree or selectors
4. Capture element screenshot with consistent naming
5. Generate element reference table in test document
6. Link screenshots to corresponding test steps

Handling Edge Cases

Element Not Visible

⚠️ Element "Submit button" not visible on initial load.
   Trigger: Appears after form validation passes.
   Action: Capture after filling required fields.

Dynamic Elements

⚠️ Element "Loading spinner" is transient.
   Capture: Use video or multiple timed captures.

Multiple Matching Elements

⚠️ Multiple "Delete" buttons found (3 instances).
   Resolution: Capture each with context or specify row/position.
   Files: delete-button-row-1.png, delete-button-row-2.png

Quality Checklist

Before finalizing element screenshots:

• Element is clearly visible and not cropped
• Sufficient padding around element
• Default state captured (unless specific state needed)
• Filename follows naming convention
• Referenced in test procedure with correct path
• Alt text or caption describes the element
