Unable to Launch any browser using selenium webdriver - eclipse

Question

I am trying to use eclipse to run Selenium web-driver automation but unable to open a browser window. Debug logs are showing that there is no error and I am successfully able to retrieve title of the web page as shown below:
try {
System.setProperty("webdriver.gecko.driver","/Users/shankar.sharma/Downloads/chrome-driver/geckodriver");
DesiredCapabilities cap = DesiredCapabilities.firefox();
cap.setCapability("marionette", true);
FirefoxOptions options = new FirefoxOptions();
options.addPreference("log", "{level: error}");
WebDriver driver = new FirefoxDriver();
driver.navigate().to("http://www.seleniumhq.org/download/");
String appTitle = driver.getTitle();
System.out.println("Application title is :: "+appTitle);
driver.quit();
} catch (Exception e) {
System.out.println("Exception:"+e.getMessage());
}
Debug Logs:

But browser window is not opening. I have also tried with chrome driver but that is also not working. I am using below configurations :
Selenium Web-driver : 3.4.0
LGecko driver : v0.16.0
Any ideas about the cause why this is happening?

Answer 1

I have checked the same in my mac but its working fine for me.. Below is the default code for which i can see the browser has been getting launched automatically...
public static void main(String[] args)
{
System.setProperty("webdriver.chrome.driver", "/Users/santhoshkumar/Documents/Softwares/chromedriver");
driver.manage().windows().maximize();
WebDriver driver = new ChromeDriver();
driver.get("http://facebook.com");
System.out.println(driver.getTitle());
}
Since this is not working for you.. Try to use chromeoptions..
public static void main(String[] args)
{
System.setProperty("webdriver.chrome.driver", "/Users/santhoshkumar/Documents/Softwares/chromedriver");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
options.addArguments("--start-fullscreen");
WebDriver driver = new ChromeDriver(options);
driver.get("http://facebook.com");
System.out.println(driver.getTitle());
}
Hope this helps you. Thanks.
