Create And Run First Webdriver Script With Eclipse

Run First Webdriver Script
You need to install webdriver with eclipse to run your script in webdriver. Before running your first selenium webdriver test, you also need to download geckodriver to run your test in mozilla firefox browser. steps to download geckodriver are as below.

Download geckodriver

  • Go to geckodriver download page.
  • On geckodriver download page, you will find latest version release of geckodriver.
  • Download geckodriver win64 version if you are working with windows 64 bit system.as shown in below image.
download geckodriver
  • You will get zip file of geckodriver.
  • Extract it. You will geckodriver.exe from extracted folder.
  • Copy and paste it at D:Selenium Files (Selenium Files folder in D: drive).

After downloading geckodriver exe and installation of webdriver software testing tool, You need to write a java code in eclipse for your test case of software web application. Let me give you one simple example of creating simple webdriver script for software web application. First of all you need to create the package called “Testing_Pack” under your project and then create new class file ‘mytestclass.java’ under that package. Now copy-paste bellow given code In your ‘mytestclass.java’ file.

package Testing_Pack;

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

public class mytestclass {

 public static void main(String[] args) {
  //set geckodriver path.
  System.setProperty("webdriver.gecko.driver","D:\Selenium Files\geckodriver.exe");
  //initialize firefox driver object to open firefox browser.
    WebDriver driver = new FirefoxDriver();
    //open URL in browser.
    driver.get("http://only-testing-blog.blogspot.com");
    String i = driver.getCurrentUrl();
    System.out.println(i);
    driver.close();
   }
}

Now you are ready to run your script from Run menu as shown bellow.

Script Explanation
Above script will 
  • open Firefox browser. 
  • Then driver.get syntax will open ‘http://only-testing-blog.blogspot.com/’ software application in firefox browser.
  • Then driver.getCurrentUrl() will get the current page URL and it will be stored in variable ‘i’. You can do same thing using “storeLocation” command in selenium IDE
  • And at last, it will print value of variable in console as shown bellow.
So this is the simple webdriver script example. You can create it for your own software web application too by replacing URL in above script. We will learn more scripts in detail in my upcoming posts.

  13. Very Helpful.
    I have a question thought. I have used selenium ide for a test case but i had to move to selenium webdriver in order to catch some errors/exceptions.
    I have also used flow control but in exported file from ide i get this: // //ERROR: Caught exception [unknown command [gotoIf]]
    How can i export ide test case as it is without having to write the case again?

  46. Looks like webdriver Is not able to find your firefox binary path. add bellow given line before WebDriver driver = new FirefoxDriver(); syntax to set binary path. It will work.

    System.setProperty("webdriver.firefox.bin","C:/Program Files/Mozilla Firefox/firefox.exe");

  65. for people having errors in selenium firefox program you need driver manager that is hosted in github

    https://github.com/bonigarcia/webdrivermanager

    steps:

    1)you need the following dependency

    io.github.bonigarcia
    webdrivermanager
    1.4.9

    2) Your program looks like this
    MarionetteDriverManager.getInstance().setup();
    WebDriver driver = new FirefoxDriver();
    driver.get("http://only-testing-blog.blogspot.in");
    String i = driver.getCurrentUrl();
    System.out.println(i);
    driver.quit();

    3) just run the program

    following are other dependecies

    org.seleniumhq.selenium
    selenium-firefox-driver
    3.0.0-beta4

    org.seleniumhq.selenium
    selenium-api
    3.0.0-beta4

  72. Just for new comer!!
    The below:
    System.setProperty("webdriver.gecko.driver","D:\Selenium Files\geckodriver.exe");
    //initialize firefox driver object to open firefox browser.
    WebDriver driver = new FirefoxDriver();

    should be:
    WebDriver driver;
    System.setProperty("webdriver.gecko.driver","D:\Selenium Files\geckodriver.exe");
    //initialize firefox driver object to open firefox browser.
    driver= new FirefoxDriver();

    Thank you Aravind G, God bless you.

    Mak
