V WebDriver - W3C WebDriver Protocol Implementation

A V language implementation of the W3C WebDriver protocol for browser automation.

Version 3.0.0 | 🎉 100% Feature Parity with Selenium 🎉 | Production Ready

🚀 Features

✅ Fully Implemented (100% Coverage) 🎉

Core Features:

  • Session Management - Create, manage, and quit browser sessions
  • Navigation - Navigate, back, forward, refresh
  • Element Location - Find elements by CSS selector, XPath, ID, class name, tag name, link text
  • Element Interaction - Click, send keys, clear, submit forms ✅ 100% Complete
  • JavaScript Execution - Execute synchronous and asynchronous scripts ✅ 100% Complete
  • Cookies - Get, add, delete, clear all cookies
  • Screenshots - Capture page and element screenshots (base64)
  • Frame Switching - Switch between frames, iframes, and parent frame
  • Actions API - Complete keyboard, mouse, wheel, drag-and-drop ✅ 100% Complete

Phase 1 & 5 - Element Properties ✨ ✅ 100% Complete:

  • Get element text, attributes, and DOM properties
  • Check visibility ( is_displayed ), enabled state ( is_enabled ), selection state ( is_selected )
  • Get tag names, clear input fields
  • Get computed CSS property values ( get_css_value ) - colors, fonts, dimensions, spacing

Phase 2 - Alert Handling ✨:

  • Accept and dismiss alert/confirm/prompt dialogs
  • Read alert text messages
  • Send text input to prompt dialogs

Phase 3 - Page Information ✨:

  • Get page title and current URL
  • Get complete HTML page source
  • Navigation verification

Phase 4 - Window & Waits ✨:

  • Switch between windows and tabs
  • Create new windows/tabs
  • Maximize, minimize, and fullscreen windows
  • Implicit waits for auto-waiting elements
  • Configurable page load and script timeouts

Phase 6 - Expected Conditions ✨:

  • Wait for elements to be clickable, visible, or present
  • Wait for specific text in elements
  • Get current timeout configuration
  • Robust wait patterns with 500ms polling

Phase 7 - Advanced Actions ✨:

  • Context click (right-click) on elements
  • Click and hold + release for drag operations
  • Drag and drop to element or by pixel offset
  • Get element position and size (rect)
  • Submit forms easily

Phase 8 - Async JS & Shadow DOM ✨ ✅ 100% Complete:

  • Execute asynchronous JavaScript with callbacks
  • Support for setTimeout, Promises, async/await patterns
  • Access Shadow DOM roots
  • Find elements within Shadow DOM
  • Test modern web components (Lit, Stencil, etc.)

Edge-Specific:

  • Network condition simulation
  • Device emulation
  • Browser version detection

fn timeouts_example() ! {
    wd := webdriver.new_edge_driver('http://127.0.0.1:9515', caps)!
    defer { wd.quit() or {} }

    // Configure timeouts
    wd.set_implicit_wait(10000)!         // Auto-wait 10s for elements
    wd.set_page_load_timeout(30000)!     // 30s page load timeout
    wd.set_script_timeout(15000)!        // 15s script timeout

    wd.get('https://example.com')!

    // Now element finding automatically waits
    element := wd.find_element('css selector', 'h1')!

    // Custom wait condition
    wd.wait_for(fn (wd webdriver.WebDriver) !bool {
        title := wd.get_title()!
        return title.len > 0
    }, 5000, 500)!
}

🌐 Multi-Browser Support

V WebDriver now supports 4 major browsers :

Browser Driver Default Port Function
Edge EdgeDriver 9515 new_edge_driver()
Chrome ChromeDriver 9515 new_chrome_driver()
Firefox GeckoDriver 4444 new_firefox_driver()
Safari SafariDriver 4445 new_safari_driver()

Browser-Specific Options

EdgeOptions / ChromeOptions :

edge_options: webdriver.EdgeOptions{
    args: ['--headless=new', '--disable-gpu', '--no-sandbox']
    binary: r'C:\Program Files\...\browser.exe'
    extensions: ['extension1.crx', 'extension2.crx']
}

FirefoxOptions :

firefox_options: webdriver.FirefoxOptions{
    args: ['-headless', '-private']
    binary: r'C:\Program Files\Mozilla Firefox\firefox.exe'
    prefs: {
        'browser.download.folderList': json.Any(2)
        'browser.download.dir': json.Any('/tmp/downloads')
    }
    profile: '/path/to/firefox/profile'
}

SafariOptions :

safari_options: webdriver.SafariOptions{
    automatic_inspection: false  // Disable Web Inspector auto-open
    automatic_profiling: false   // Disable profiling auto-start
}

All browsers support standard W3C capabilities like accept_insecure_certs , page_load_strategy , timeouts , and proxy settings.

🤝 Contributing

Contributions are welcome! Now that 100% feature parity is achieved, focus areas include:
