How to Setup Selenium with Firefox on Ubuntu

    RahulBy 3 Mins ReadUpdated:

    Selenium is an automated web testing framework. Using this we can automate the browser functioning for testing any web application. Using selenium you can run predefined code to navigate between multiple pages and test application with predefined rules. This tutorial will help you to setup Selenium with Firefox on Ubuntu, Debian and LinuxMint systems.

    Step 1 – Prerequisites

    Execute the following commands to install required packages on your system. Here Xvfb (X virtual framebuffer) is an in-memory display server for a UNIX-like operating system (e.g., Linux). It implements the X11 display server protocol without any display. This is helpful for CLI applications like CI service.

    sudo apt-get update
sudo apt-get install -y unzip xvfb libxi6 libgconf-2-4

    Also, install Java on your system. Use the below command to install the latest available java version.

    sudo apt-get install default-jdk

    Step 2 – Install Firefox with Driver

    Firefox is available under default apt repositories. You can simply install it by running the following command from the command prompt.

    sudo apt-get -y install firefox

    Also, download the geckodriver for the firefox.

    wget https://github.com/mozilla/geckodriver/releases/download/v0.25.0/geckodriver-v0.25.0-linux64.tar.gz
tar xzf geckodriver-v0.25.0-linux64.tar.gz
sudo mv geckodriver /usr/bin/geckodriver

    Step 3 – Download Selenium Server Jar

    The Selenium Server is required to run Remote Selenium WebDrivers. You need to download the Selenium standalone server jar file using the below commands or visit here to find the latest version of Jar file.

    mkdir ~/selenium && cd ~/selenium 
wget https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar

    Also download the testng-6.5.1.jar file to your system.

    wget http://www.java2s.com/Code/JarDownload/testng/testng-6.5.1.jar.zip
unzip testng-6.5.1.jar.zip

    Step 4 – Start Selenium Server

    Your server setup is ready. Start the standalone selenium server using Xvfb utility.

    Run Selenium Server 

    DISPLAY=:1 xvfb-run java -jar ~/selenium/selenium-server-standalone-3.13.0.jar

    Your Selenium server is now running with firefox. Use this server to run your test cases written in Selenium using the Firefox web browser.

    Step 5 – Sample Java Program (Optional)

    This is an optional step. It describes running a single test case using Selenium standalone server and FirefoxDriver. This Java program will open a specified website URL and check if defined string presents on the webpage or not.

    Create a Java program by editing a file in a text editor.

    vim TecAdminSeleniumTest.java

    Add the below content to file.

    import java.io.IOException;
     
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.firefox.FirefoxBinary;
    import org.openqa.selenium.firefox.FirefoxDriver;
    import org.openqa.selenium.firefox.FirefoxOptions;
    import org.testng.annotations.Test;
     
    public class TecAdminSeleniumTest {
     
    public static void main(String[] args) throws IOException, InterruptedException {
     
    FirefoxBinary firefoxBinary = new FirefoxBinary();
    firefoxBinary.addCommandLineOptions("--headless");
    firefoxBinary.addCommandLineOptions("--no-sandbox");
    System.setProperty("webdriver.gecko.driver", "/usr/bin/geckodriver");
    FirefoxOptions firefoxOptions = new FirefoxOptions();
    firefoxOptions.setBinary(firefoxBinary);
    FirefoxDriver driver = new FirefoxDriver(firefoxOptions);
    driver.get("https://google.com");
     
    Thread.sleep(1000);
     
    if (driver.getPageSource().contains("kkkI'm Feeling Lucky")) {
    System.out.println("Pass");
    } else {
    System.out.println("Fail");
    }
    driver.quit();
    }
    }

    You can change the URL “https://google.com” with any other URL of your choice, Then also change the search string like “I’m Feeling Lucky” used in the above Java program. Save your java program and execute it. First, you need to set the Java CLASSPATH environment variable including the selenium-server-standalone-3.141.59.jar and testng-6.5.1.jar. Then compile the java program and run it.

    export CLASSPATH=".:selenium-server-standalone-3.141.59.jar:testng-6.5.1.jar"

    Now, compile your Java program and run it.

    javac TecAdminSeleniumTest.java
java TecAdminSeleniumTest

    If the defined search string found, You will get message “Pass” and if string not found on the webpage, you will get the “Fail” message on the screen.

    Share.

      At the end you write: “Start the Chrome via standalone selenium server using Xvfb utility.”
      isn’t it for firefox?!

        Maybe it’s because you need to find the directory where selenium-server-standalone-3.13.0.jar downloaded. In my directory I found that file in /home/selenium-server-standalone-3.13.0.jar.
