What is Jenkins?
Jenkins is a well-known open-source tool that aids in the implementation of Continuous Integration (CI) and Continuous Deployment/Continuous Delivery (CD) processes by automating parts of the software development pipeline such as building, testing, and deployment.
What is Selenium?
Selenium is an open-source automation tool that has been widely used for testing web applications. It is basically a suite of software or a set of JAR files to automate web browsers across various browsers. Selenium is used by many companies, but a few to mention are Netflix, Google, HubSpot, Fitbit, and more. Selenium supports multiple languages like Python, Pearl, Ruby, .Net, Java, C#, PHP.
Selenium supports parallel test execution. That means we can open multiple browsers at the same time and execute the test cases. This decrease the execution time significantly. Selenium supports Cross browser test execution.
Jenkins Integration With Selenium
It is recommended to go through these tutorials:-
Download and install Jenkins on Windows10
Configure JAVA_HOME and MAVEN_HOME
Implementation Steps
Step 1 – Create a project for running the tests using Selenium WebDriver and TestNG
Step 2 – Create the Test Code
Below is the sample POM.xml.

BasePage
package com.example;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.PageFactory;
public class BasePage {
public WebDriver driver;
public BasePage(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver,this);
}
}

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
public class HomePage extends BasePage {
public HomePage(WebDriver driver) {
super(driver);
}
@FindBy(xpath = "//*[@id='app']/div[1]/div[1]/header/div[1]/div[1]/span/h6")
public WebElement homePageUserName;
public String getHomePageText() {
return homePageUserName.getText();
}
}
LoginPage
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
public class LoginPage extends BasePage{
public LoginPage(WebDriver driver) {
super(driver);
}
@FindBy(name = "username")
public WebElement userName;

userName.sendKeys(strUserName);
password.sendKeys(strPassword);
login.click();
}
public String getErrorMessage() {
return errorMessage.getText();
}
}
BaseTests
import java.time.Duration;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import io.github.bonigarcia.wdm.WebDriverManager;
public class BaseTests {

driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("https://opensource-demo.orangehrmlive.com/");
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(TIMEOUT));
}
@AfterMethod
public void tearDown() {

import org.testng.annotations.Test;
public class LoginPageTests extends BaseTests{
@Test
public void invalidCredentials() {
LoginPage objLoginPage = new LoginPage(driver);
objLoginPage.login("admin$$", "admin123");
// Verify Error Message
Assert.assertEquals("Invalid credentials",objLoginPage.getErrorMessage());
}
@Test
public void validLogin() {
LoginPage objLoginPage = new LoginPage(driver);
objLoginPage.login("Admin", "admin123");

// Verify Home Page
Assert.assertEquals("Dashboard",objHomePage.getHomePageText());
}
}
Step 3 – Start Jenkins
