/**
 * A {@link WebDriver} implementation that controls a Blink-based Opera browser running on the local
 * machine. This class is provided as a convenience for easily testing the Chrome browser. The
 * control server which each instance communicates with will live and die with the instance.
 *
 * To avoid unnecessarily restarting the OperaDriver server with each instance, use a
 * {@link RemoteWebDriver} coupled with the desired {@link OperaDriverService}, which is managed
 * separately. For example: <pre>{@code
 *
 * import static org.junit.Assert.assertEquals;
 *
 * import org.junit.*;
 * import org.junit.runner.RunWith;
 * import org.junit.runners.JUnit4;
 * import org.openqa.selenium.opera.OperaDriverService;
 * import org.openqa.selenium.remote.DesiredCapabilities;
 * import org.openqa.selenium.remote.RemoteWebDriver;
 *
 * {@literal @RunWith(JUnit4.class)}
 * public class OperaTest extends TestCase {
 *
 *   private static OperaDriverService service;
 *   private WebDriver driver;
 *
 *   {@literal @BeforeClass}
 *   public static void createAndStartService() {
 *     service = new OperaDriverService.Builder()
 *         .usingDriverExecutable(new File("path/to/my/operadriver.exe"))
 *         .usingAnyFreePort()
 *         .build();
 *     service.start();
 *   }
 *
 *   {@literal @AfterClass}
 *   public static void createAndStopService() {
 *     service.stop();
 *   }
 *
 *   {@literal @Before}
 *   public void createDriver() {
 *     driver = new RemoteWebDriver(service.getUrl(),
 *         DesiredCapabilities.opera());
 *   }
 *
 *   {@literal @After}
 *   public void quitDriver() {
 *     driver.quit();
 *   }
 *
 *   {@literal @Test}
 *   public void testGoogleSearch() {
 *     driver.get("http://www.google.com");
 *     WebElement searchBox = driver.findElement(By.name("q"));
 *     searchBox.sendKeys("webdriver");
 *     searchBox.quit();
 *     assertEquals("webdriver - Google Search", driver.getTitle());
 *   }
 * }
 * }</pre>
 *
 * Note that unlike OperaDriver, RemoteWebDriver doesn't directly implement
 * role interfaces such as {@link LocationContext} and {@link WebStorage}.
 * Therefore, to access that functionality, it needs to be
 * {@link org.openqa.selenium.remote.Augmenter augmented} and then cast
 * to the appropriate interface.
