Mude para:

"C:\Selenium\chromedriver.exe"

Até mais!

Caso ainda nao funcione, tente o seguinte "C://Selenium//chromedriver.exe"

Seu executavel está na pasta Selenium ou na pasta chromedriver?

Deu certo! Obrigado.

Estou tendo problema ao executar o teste no Chrome, está dando o seguinte erro no terminal:

Segue abaixo o código executado:

        System.setProperty("webdriver.chrome.driver", "C:\\drivertestesautomatizados\\chromedriver.exe"); 
        WebDriver driver = new ChromeDriver();
        driver.get("http://www.bing.com/");
        WebElement q = driver.findElement(By.name("q"));
        q.sendKeys("Caelum");
        q.submit();

Já verifiquei a versão do Browser.
