Selenium Webdriver Error w/ Java

Question

Hey guys Im trying to run an example code of Selenium using the Java libs. The code is the sample code from the website but I receive an error on run. I am not sure what I am supposed to do as the error isn't specific. I am running OS X 10.11.6 with selenium 3 java libs. I am using Eclipse. Safari is currently version 10.01 with "Allow Remote Automation" from the safari develop menu enabled. Code:

 package seleniumPackage; import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.safari.SafariDriver; import org.openqa.selenium.support.ui.ExpectedCondition; import org.openqa.selenium.support.ui.WebDriverWait; //import org.openqa.selenium.By; //import org.openqa.selenium.WebDriver; //import org.openqa.selenium.WebElement; //import org.openqa.selenium.firefox.FirefoxDriver; //import org.openqa.selenium.support.ui.ExpectedCondition; //import org.openqa.selenium.support.ui.WebDriverWait; public class Selenium2Example { public static void main(String[] args) { // Create a new instance of the Firefox driver // Notice that the remainder of the code relies on the interface, // not the implementation. WebDriver driver = new SafariDriver(); // And now use this to visit Google driver.get("http://www.google.com"); // Alternatively the same thing can be done like this // driver.navigate().to("http://www.google.com"); // Find the text input element by its name WebElement element = driver.findElement(By.name("q")); // Enter something to search for element.sendKeys("Cheese!"); // Now submit the form. WebDriver will find the form for us from the element element.submit(); // Check the title of the page System.out.println("Page title is: " + driver.getTitle()); // Google's search is rendered dynamically with JavaScript. // Wait for the page to load, timeout after 10 seconds (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() { public Boolean apply(WebDriver d) { return d.getTitle().toLowerCase().startsWith("cheese!"); } }); // Should see: "cheese! - Google Search" System.out.println("Page title is: " + driver.getTitle()); //Close the browser driver.quit(); } } 

Error Message:

Answer 1

I don't think that the port is blocked, it's because the underlying Selenium server is not running on that port.

I ran into the same "ConnectionException connection refused", when the safaridriver process was not killed from a previous run. On subsequent runs, the example's SafariDriver could not start the underlying Selenium server due to the existing process. The driver printed the following error

"Unable to start the server: another safaridriver is already running (@ localhost:35040)"

and threw "ConnectionException Connection refused" because it could not connect to the new Selenium server which used a different port from the existing process.

I think only one instance of the SafariDriver is allowed at a time, and each instance uses a random port. Thus the example instantiates the SafariDriver, but the underlying Selenium server can't start because an instance is already running. The driver then tries to connect to the new instance using the port it expects (which is different than the existing instance), and throws a ConnectionException.

Answer 2

"Unable to start the server: another safaridriver is already running (@ localhost:35040)"

Kill the Safaridriver if already running..follow below steps:

1. Open terminal and type command launchctl list | grep webdriverd launchctl list | grep webdriverd
2. We will get running port and kill the port as mention command sudo kill *****

Now its working Fine
