Vebidor - W3C WebDriver Protocol Implementation

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

Version 5.1.0 | Playwright-style API + WebDriver-BiDi + native iOS/Android + codegen | 100% Selenium parity | Production Ready

⚡ Modern API (Playwright-style)

Beyond the raw W3C WebDriver methods, Vebidor ships a higher-level ergonomic layer: one-call browser launch, lazy auto-waiting Locators, semantic selector engines, and retrying web-first assertions.

import vebidor.webdriver

fn main() {
	// Auto-detects the driver + browser, picks a free port, and tears
	// everything down on close(). No manual "start chromedriver" step.
	mut b := webdriver.launch_edge(webdriver.LaunchOptions{ headless: true })!
	defer { b.close() }

	b.goto('https://example.com')!

	// Locators are lazy and auto-wait for the element to be actionable.
	b.wd.get_by_role('link', 'More information...').click()!

	// Web-first assertions poll until the condition holds (or time out).
	webdriver.expect(b.wd.get_by_role('heading', '')).to_be_visible()!
}

Selector engines: get_by_role, get_by_text, get_by_label, get_by_placeholder, get_by_test_id, plus wd.locator('css=...' | 'xpath=...') with chaining (row.locator('td')) and nth(i) / first().

Auto-waiting actions: click, fill, type_text, clear wait for the element to be attached, visible, enabled, and scrolled into view.

Assertions: to_be_visible / to_be_hidden / to_be_enabled / to_be_disabled, to_have_text / to_contain_text / to_have_value / to_have_attribute / to_have_count, each invertible via .not() and tunable via .with_timeout(ms).

WebDriver-BiDi (bidirectional)

Launch with bidi: true to get a persistent WebSocket alongside the Classic session, unlocking event-driven features Classic cannot offer — network interception/mocking, console/network listeners, isolated contexts, and more.

mut b := webdriver.launch_edge(webdriver.LaunchOptions{ headless: true, bidi: true })!
defer { b.close() }
mut bidi := b.bidi()!
defer { bidi.close() }
ctx := bidi.first_context()!

// Mock a response (Playwright route.fulfill style).
bidi.route(fn (req webdriver.InterceptedRequest) {
	if req.url.contains('/api') {
		req.fulfill(200, 'application/json', '{"mocked":true}') or {}
	} else {
		req.continue_request() or {}
	}
})!

bidi.add_preload_script('() => { window.__patched = true }')!   // runs before page scripts
bidi.navigate(ctx, 'https://example.com')!
bidi.on_log(fn (e webdriver.LogEntry) { println('${e.level}: ${e.text}') })!

BiDi capabilities: request/response interception + mocking (route, route_response, fulfill/abort/continue), HTTP auth (on_auth), console/network events (on_log/on_request/on_response), wait_for_event, isolated user contexts (with per-context proxy, geolocation, permissions, and storageState session reuse), preload scripts + call_function, viewport emulation, partition-aware cookies (get_cookies(user_context: uc)) + on_cookie_changed, screenshots/PDF, file upload (set_files), and a Tracer. Capability probing via status() / supports(). Any unwrapped command/event is reachable via send/on (or on_sync for inline observers).

Mobile emulation (Playwright-style): device presets (emulate_device(ctx, 'iPhone 14'), 9 built-in), emulate() for viewport/DPR/UA/ touch flags, Locator.tap(), set_request_user_agent (server-side UA), and set_locale/set_timezone/set_screen_orientation. (Real touch-event dispatch needs a CDP/mobileEmulation capability BiDi doesn't expose; touch detection is emulated.)

📦 Installation

Prerequisites

1. V compiler installed
2. A supported browser (Edge, Chrome, Firefox, or Safari)
3. Matching WebDriver:
   • Edge: EdgeDriver (port 9515)
   • Chrome: ChromeDriver (port 9515)
   • Firefox: GeckoDriver (port 4444)
   • Safari: Built-in SafariDriver on macOS (port 4445)

Install the module

The fastest way to get vebidor onto V's module path:

v install vebidor

This pulls the module so import vebidor.webdriver and import vebidor.mobile resolve from anywhere. To track main instead of a published release, clone and symlink the checkout:

git clone https://github.com/quaesitor-scientiam/vebidor.git
cd vebidor
mkdir -p ~/.vmodules
ln -s "$(pwd)" ~/.vmodules/vebidor
# (Alternatively: `v install` from this directory.)

Quick Setup

Tip: With the Modern API launch(), you can skip the manual driver-start step below — Vebidor finds the driver on PATH (or via EDGEDRIVER/CHROMEDRIVER/GECKODRIVER), starts it on a free port, and stops it for you. The steps below are for the classic new_*_driver(url, caps) flow that connects to a driver you started yourself.

# Start your browser's WebDriver
# Edge/Chrome:
.\msedgedriver.exe --port=9515  # or chromedriver.exe

# Firefox:
.\geckodriver.exe --port=4444

# Safari (macOS):
safaridriver --enable
safaridriver -p 4445

📱 Native Mobile (iOS + Android)

Beyond browser automation, Vebidor ships a native mobile module (vebidor.mobile) that drives real apps on iOS and Android — by talking directly to WebDriverAgent (iOS) and the UiAutomator2 server (Android), the same on-device backends Appium uses, but with no Node middleware.

import vebidor.mobile

mut s := mobile.launch_android(mobile.AndroidOptions{
    mode: .spawn
    udid: 'emulator-5554'
    app_package: 'com.android.settings'
    app_activity: '.Settings'
    uia2_server_apk: server_apk
    uia2_server_test_apk: test_apk
})!
defer { s.close() }

// Same Playwright-style surface as the web module:
mobile.expect(s.get_by_text('Battery')).to_be_visible()!
s.get_by_label('Battery').tap()!
s.set_orientation(.landscape)!

One API, two backends. Cross-platform get_by_label/text/test_id/role selectors, lazy auto-waiting locators, expect() assertions, touch gestures, app lifecycle, and device state (orientation, lock, geolocation, network) — all sharing the web module's transport and polling engine. The Android path is verified live on an emulator; iOS on a Simulator.

🎯 Feature Coverage

Current: 🎉 100% feature parity with Selenium WebDriver! 🎉 ALL Phases Complete! 🎊

🏆 100% FEATURE PARITY ACHIEVED! 🏆

See COMPARISON_WITH_PLAYWRIGHT.md for the full Playwright/Selenium feature mapping.

✨ What's New in v5.1.0

🎬 Codegen / session recorder — record a live session and emit runnable vebidor source via tools/codegen.v. Web capture runs over WebDriver-BiDi; native mobile capture is new — Android is passive (taps read from adb getevent, hit-tested against the live accessibility tree), iOS is an assisted REPL. Both synthesize semantic get_by_* locators rather than brittle coordinates. Verified live on the Android emulator (5/5 synthesized selectors re-resolved on-device). See CODEGEN_HANDOFF.md.

✨ What's New in v5.0.0

📱 Native mobile automation — a new vebidor.mobile module that drives real apps on iOS (via WebDriverAgent) and Android (via the UiAutomator2 server) directly over their HTTP sockets — the same backends Appium uses, with no Node middleware. Sibling to vebidor.webdriver; shares its HttpTransport, lazy auto-waiting locator, and poll_until_true assertion engine.

• ✅ One-call launch — launch_ios(.simulator) / launch_android(.spawn) boot the Simulator/emulator, spawn the backend, port-forward, poll readiness, and tear it all down on close()
• ✅ Cross-platform selectors — get_by_role / get_by_label / get_by_text / get_by_test_id compile to XCUITest predicates (iOS) and UiAutomator selectors (Android)
• ✅ Auto-waiting actions + W3C-actions gestures — tap / fill / swipe_* / long_press / drag_to / scroll_into_view
• ✅ Web-first assertions — mobile.expect(loc).to_be_visible() with .not() / .with_timeout()
• ✅ App lifecycle + device state — activate_app / terminate_app / query_app_state, lock / unlock, set_orientation, set_geolocation, set_network_condition
• 📄 See COMPARISON_WITH_APPIUM.md and MOBILE_TESTING.md

Verified live: full Android path on an Android Emulator (Pixel AVD, API 34); iOS sessions, selectors, assertions, and gestures on an iOS Simulator.

✨ What's New in v4.2.0

📱 Playwright-style mobile-web emulation (over WebDriver-BiDi):

• ✅ Device presets — emulate_device(ctx, 'iPhone 14') (9 built-in: iPhone, Pixel, Galaxy, iPad)
• ✅ emulate() — viewport + DPR + JS-visible UA + isMobile/hasTouch
• ✅ Locator.tap() (touch pointer)
• ✅ set_request_user_agent — server-side UA (HTTP header rewrite)
• ✅ set_locale / set_timezone / set_screen_orientation
• ⚠️ Real touch-event dispatch needs a CDP/mobileEmulation capability BiDi doesn't expose (touch detection is emulated; tap synthesizes a click)

(v4.1.0: per-context conveniences + capability probing; v4.0.1: partition-aware cookies + inline dispatch — see CHANGELOG.)

✨ What's New in v4.0.0

🎭 Playwright-style API + WebDriver-BiDi — verified live against headless Edge

• ✅ Locators: lazy, auto-waiting, chainable, staleness-immune (get_by_role/text/label/placeholder/test_id, nth/first)
• ✅ Web-first assertions: expect(loc).to_be_visible() etc., polling, .not() / .with_timeout()
• ✅ launch(): auto-detect driver+browser, free port, teardown — no manual driver start
• ✅ WebDriver-BiDi transport: persistent WebSocket coexisting with the Classic session
• ✅ Network interception/mocking: route/route_response, fulfill/abort/continue, on_auth
• ✅ Events: console/network listeners, wait_for_event, on_cookie_changed
• ✅ Isolated user contexts, preload scripts, call_function, viewport emulation
• ✅ File upload (set_files), BiDi cookies, screenshots/PDF, Tracer
• 🐛 Fixed: W3C screenshot endpoints now use GET (were POST)

vebidor now offers Playwright-style ergonomics and WebDriver-BiDi coverage that meets or exceeds Selenium's, on a native V API. See COMPARISON_WITH_PLAYWRIGHT.md.

✨ What's New in v3.1.1

🐛 Multi-Browser Bug Fixes - All 4 browsers now fully functional!

• ✅ v3.1.1: Fixed compile error (new_session() helper), Safari W3C JSON tags, moved new_edge_driver() to edge.v, standardized parameter names
• ✅ v3.1.0: Added Chrome, Firefox, and Safari browser support alongside Edge
• ✅ v3.0.1: Added find_edge_binary helper for automatic Edge binary detection
• ✅ v3.0.0: Phase 8 Complete - 100% Feature Parity with Selenium achieved!

Total: 40 methods added across all phases, raising feature parity from 55% to 100%! 🎉

🏆 100% FEATURE PARITY WITH SELENIUM WEBDRIVER ACHIEVED! 🏆

🌐 Multi-Browser Support

Vebidor now supports 4 major browsers:

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.

Status: Production-ready for web automation (Playwright-style API + WebDriver-BiDi on top of 100% Selenium parity) and native mobile automation (iOS via WebDriverAgent + Android via UiAutomator2). 🎉

Version: 5.1.0 (adds a codegen recorder for web + native mobile — emits semantic get_by_* locators; on top of v5.0.0's vebidor.mobile and the unchanged web stack: Playwright-style Locators/assertions, launch(), WebDriver-BiDi, mobile emulation, 4-browser support)

Selenium-parity phases: ✅ Phase 1 | ✅ Phase 2 | ✅ Phase 3 | ✅ Phase 4 | ✅ Phase 5 | ✅ Phase 6 | ✅ Phase 7 | ✅ Phase 8

Playwright-parity roadmap: ✅ Phase 0 (transport seam) | ✅ Phase 1 (locators/assertions) | ✅ Phase 2 (launch) | ✅ Phase 3 (BiDi transport) | ✅ Phase 4 (BiDi features) | ✅ Phase 5 (tooling) | ✅ BiDi gap closure vs Selenium

Latest Update: 2026-06-03 - v5.1.0 codegen recorder for web + native mobile (a11y-tree → semantic get_by_* locators; mobile capture verified live on the Android emulator)
