I see an error while running a package in Eclipse

Question

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver . The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases

This is my code.

package newpackage;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class MyClass {

    public static void main(String[] args) {
        //declaration and instatiation of objects/variables

        WebDriver driver = new FirefoxDriver();
        String baseUrl = "http://newtours.demoaut.com";
        String expectedTitle = "Welcome: Mercury Tours";
        String actualTitle ="";

        //launch firefox and direct it to the URL

        driver.get(baseUrl);

        //get the actual value of the title

        actualTitle = driver.getTitle();



        if (actualTitle.contentEquals(expectedTitle)){
            System.out.println("Test Passed");

        }else {
            System.out.println("Test failed");
        }


        //close firefox

        driver.close();

        //exit the program

        System.exit(0);

    }

}

Answer 1

For selenium 3.0 and above it is mandatory to specify gecko.driver path. Add below lines to your code before initializing driver and error will not appear.

System.setProperty("webdriver.firefox.marionette","xxx\geckodriver.exe");
//xxx - path to geckodriver.exe file
WebDriver driver = new FirefoxDriver();
