standard</a>. WebDriver is an open source tool built for automated testing of web apps across many browsers. Its interface allows for control and introspection of user agents locally or remotely using capabilities.</p> <p>Capabilities are a language-neutral set of key-value pairs used to define the desired features and behavior of a WebDriver session. Capabilities are typically passed as an argument when creating a WebDriver instance, and can be used to specify browser settings, such as the browser name, version, and page loading strategy.</p> <p>ChromeDriver extends Webdriver by adding Chromium-specific capabilities. It uses the <code translate="no" dir="ltr">ChromeOptions</code> object to pass capabilities to ChromeDriver from the WebDriver API. Some Chromium-specific capabilities include the ability to install extensions, change window types, and pass command line arguments on startup. </p> <p>ChromeDriver is available for Chrome on Android and Chrome on Desktop (Mac, Linux, Windows and ChromeOS).</p> <p>You can view the current implementation status of the WebDriver standard <a href="https://chromium.googlesource.com/chromium/src/+/master/docs/chromedriver_status.md">here</a>.</p> <h2 id="latest_chromedriver_binaries" data-text="Latest ChromeDriver binaries" tabindex="-1">Latest ChromeDriver binaries</h2> <ul> <li>Starting with M115 the latest Chrome + ChromeDriver releases per release channel (Stable, Beta, Dev, Canary) are available at <a href="https://googlechromelabs.github.io/chrome-for-testing/">the Chrome for Testing availability dashboard</a>.
