Features Implemented

Locator Strategies (8)

1. Test ID (getByTestId) - Most reliable
2. ARIA Role (getByRole) - Accessibility-first
3. Label (getByLabel) - Form inputs
4. Placeholder (getByPlaceholder) - Input fields
5. Alt Text (getByAltText) - Images
6. Title (getByTitle) - Tooltips
7. Text Content (getByText) - Visible text
8. CSS Selector (locator) - Complex queries

Actions (25+)

• Navigation: navigate, reload, goBack, goForward, waitForLoadState
• Interaction: click, fill, type, select, hover, focus, blur
• Input: press, keyboard, scroll
• Waiting: waitForNavigation, waitForSelector, waitForURL, wait
• Utilities: screenshot, evaluate

Assertions (20+)

• Visibility: toBeVisible, toBeHidden
• State: toBeEnabled, toBeDisabled, toBeChecked, toBeEmpty, toBeEditable
• Content: toContainText, toHaveText
• Attributes: toHaveAttribute, toHaveClass, toHaveValue, toHaveCount
• Styling: toHaveCSS (complex checks)
• Visual: toHaveScreenshot, toBeInViewport
• Page: toHaveURL, toHaveTitle
• Custom: custom JavaScript

How to Use

Run Tests

npm run test:e2e

View Report

npm run test:e2e:report

Write New Tests

Create packages/my-package/playwright/tests.json:

{
  "$schema": "https://metabuilder.dev/schemas/package-playwright.schema.json",
  "package": "my_package",
  "tests": [
    {
      "name": "Should do something",
      "steps": [
        {"action": "navigate", "url": "/page"},
        {"action": "click", "testId": "button"},
        {"action": "expect", "testId": "result", "assertion": {"matcher": "toBeVisible"}}
      ]
    }
  ]
}

Tests are auto-discovered and executed.
