Selenium

OS	Chrome	Firefox	Edge	Safari

Windows

Selenium is a native D implementation of the W3C WebDriver protocol. It drives Chrome, Firefox, Edge, and Safari directly over HTTP, with no external language bindings or C wrappers. The API often mirrors the Selenium Ruby bindings, so it should be familiar to existing Selenium users.

Installation

Add the complete package or a specific subpackage with DUB:

dub add selenium
dub add selenium:webdriver
dub add selenium:grid

Package	Contents
selenium	WebDriver and Grid modules.
selenium:webdriver	Bridge, driver, browser capabilities, elements, roots, cookies, and logging.
selenium:grid	Grid models, hub and node scaffolding, and in-process HTTP routing.

The Grid package currently provides models and routing primitives, not a live HTTP server or a complete session distributor.

Quick Start

Install the browser and matching WebDriver executable, then ensure the driver is on PATH:

Browser	WebDriver executable
Chrome	chromedriver
Firefox	geckodriver
Edge	msedgedriver
Safari	safaridriver

import selenium;

import std.stdio : writeln;

Driver driver = Driver.start(new Chrome());
scope (exit) driver.stop();

driver.go("https://example.com");
writeln(driver.title);

Driver.start() can instead select the first known WebDriver executable found on PATH. The library does not download browsers or drivers.

Roadmap

WebDriver protocol

• Fix Safari support (see integration tests)
• Asynchronous script execution (POST /execute/async)
• Actions API, including perform and release
• Alert text, accept, dismiss, and prompt input commands
• Computed accessibility role and label accessors
• Page printing (POST /print)
• First-class timeout retrieval and updates
• Full window rectangle support, including window position

Client API

• Explicit waits with reusable expected conditions
• Special keys such as Enter, Tab, Escape, and arrows for sendKeys
• Convenience locators such as id, name, and class name
• Element display state (isDisplayed)
• Select-element helper

Grid

• Live HTTP transport for hubs and nodes
• Node registration, heartbeat, draining, and removal
• Capability matching, session allocation, and command forwarding

Quality

• Grid server and client (multi-session routing) tests
• W3C WebDriver compliance tests
• More than 70% code coverage for every source file
