Easy to use Node.js based end-to-end testing solution for web applications using the W3C WebDriver API.

/**
 * Ends the session and closes down the test WebDriver server, if one is running. This is similar to calling the .end() command, but the former doesn't quit the WebDriver session.
 *
 * This command will also execute the `onBrowserQuit()` global, if one is defined.
 *
 * @example
 * this.demoTest = function (browser) {
 *   browser.quit(function(result) {
 *     console.log(result.value);
 *   });
 * }
 *
 * @method quit
 * @syntax .quit([callback])
 * @param {function} [callback] Optional callback function to be called when the command finishes.
 * @api protocol.sessions
 * @since 2.0.0
