title: Remote webdriver with opera and edge browser
body: <p>Can't connect to opera and edge webdriver through hub. 
  My procedure:</p>
  
  <ul>
  <li><p>start hub in cmd:</p>
  
  <pre><code>   java -jar C:\path\to\selenium-server-standalone-3.7.1.jar -role hub 
  </code></pre></li>
  <li><p>start node in cmd:</p>
  
  <pre><code>        java -Dwebdriver.opera.driver=C:\path\to\operadriver.exe -
          Dwebdriver.edge.driver=C:\path\to\MicrosoftWebDriver.exe -jar 
          C:\path\to\selenium-server-standalone-
          3.7.1.jar -role node -hub http://mylocalhost:4444/grid/register 
          -browser "browserName=opera,maxInstances=5,platform=Windows" -
          browser "browserName=edge,maxInstances=5,platform=Windows"
  </code></pre></li>
  </ul>
  
  <p>And run this test for Opera:</p>
  
  <pre><code>               WebDriver driver;
                 String nodeURL;
                 nodeURL = "http://mylocalhost:5555/wd/hub";
          DesiredCapabilities capabilities = new DesiredCapabilities();
          capabilities.setBrowserName("opera");
          capabilities.setPlatform(Platform.WINDOWS);
          driver = new RemoteWebDriver(new URL(nodeURL), capabilities);
          driver.get("https://www.google.ru/");
  </code></pre>
  
  <p>And for Edge:</p>
  
  <pre><code>               WebDriver driver;
                 String nodeURL;
                 nodeURL = "http://mylocalhost:5555/wd/hub";
          DesiredCapabilities capabilities = new DesiredCapabilities();
          capabilities.setBrowserName("opera");
          capabilities.setPlatform(Platform.WINDOWS);
          driver = new RemoteWebDriver(new URL(nodeURL), capabilities);
          driver.get("https://www.google.ru/");
  </code></pre>
  
  <p>This is cause exception for Opera:</p>
  
  <pre><code>    org.openqa.selenium.WebDriverException: unknown error: cannot find Opera binary
  </code></pre>
  
  <p>And exception for Edge:</p>
  
  <pre><code>org.openqa.selenium.SessionNotCreatedException: Unable to create new service: ChromeDriverService
  </code></pre>
  
  <p>I know that this code work fine for Chrome and firefox. Anyone know how to apply this for Opera ana Edge?</p>
