What is Selenium?
Selenium is an open-source framework that can be used to perform automated browser testing of websites and web applications. It is a versatile framework for testing across different environments due to its cross-browser, cross-language, and cross-platform capabilities. Selenium integrates with existing development workflows and supports programming languages like Java, JavaScript, Python, and more.
Moreover, Selenium offers cross-browser compatibility with major browsers like Chrome, Firefox, Safari, Edge, and Opera. Furthermore, you can leverage the immense capability offered by Selenium flexibility to perform automation testing with testing frameworks like TestNG, JUnit, MSTest, pytest, and more.
Components of Selenium
Selenium framework consists of three primary components: Selenium WebDriver, Selenium Grid, and Selenium IDE.
- Selenium WebDriver: It is an integral part of the Selenium suite used for automating web application testing. It offers developers and testers an interface to effortlessly create and execute test scripts that mimic user interactions with web browsers. These interactions include clicking on links, completing forms, and retrieving web page information. The versatility of Selenium WebDriver allows these actions to be performed on local machines and remote grids.
- Selenium Client Libraries
- WebDriver W3C Protocol
- Browser Drivers
- Real Web Browsers
- Selenium Grid: Selenium Grid allows multiple test scripts to be executed simultaneously across different browsers, operating systems, and machines. Its hub-and-node architecture serves as a central control point for the network of test machines (nodes).
- Selenium IDE: Selenium IDE is an extension for Chrome, Firefox, and Edge that simplifies the process of recording and executing tests directly within the browser. Its user-friendly interface and built-in functionality allow testers to quickly create reliable tests without any additional setup requirements.
The latest version of Selenium 4 introduces a new architecture for Selenium WebDriver, which revolves around four essential components. These components play a crucial role in enhancing the functionality of Selenium.
This setup enables distributed testing, significantly reducing the time required for cross-browser and cross-platform testing. The Grid also facilitates parallel execution of tests, improving testing efficiency and coverage. It proves particularly beneficial in large-scale test environments and continuous integration pipelines.
The latest version of Selenium, Selenium 4, was released in October 2021 and introduces significant updates compared to its predecessor, Selenium 3. One key feature in Selenium 4 is the adoption of the W3C WebDriver Protocol, which replaces the JSON Wire Protocol used in Selenium 3. This update brings enhanced capabilities to the framework.
Moreover, Selenium IDE offers advanced debugging capabilities like breakpoints and exception pausing, which enhance troubleshooting efficiency. Another benefit of using Selenium IDE is its automated cross browser testing support. This means you can run your tests on various browsers and operating systems using the Command-line Runner.

Getting Started: Automation Testing Using Selenium With Java
If you’re new to automation or moved from manual to automation testing, Selenium WebDriver is the best place to start. It has everything that you need to kickstart your Selenium automation journey.
In this section of this article on Selenium with Java, I will take you through the prerequisites and everything you need to know about Selenium to get started with automation testing with Java.
The latest version, Selenium 4, comes with numerous major revamps, including enhanced architecture and advanced features. You can go through this Selenium 4 tutorial to learn what is new in Selenium 4.
How Does Selenium WebDriver Work?
The Selenium WebDriver works with a client-server architecture model.
We have the Selenium client library on the client side, which supports multiple client libraries corresponding to the programming language being used, like Java, Python, Ruby, etc. The language binding feature of Selenium allows it to support various programming languages. Based on the programming language of the test scripts, we need to choose the client library. For example, you need to use the Java language bindings to use Selenium with Java. You can download your respective language bindings from the Selenium Downloads Page.
We have the browser driver on the server side, which accepts the HTTP requests coming from the client side via the communication protocol. The browser driver then interacts with the real browser and drives it to execute the actions defined in the automation scripts. Every browser has a browser driver specific to it. For example, you need to use the Chrome driver to automate the Chrome browser. Below are the locations where you can download the respective browser driver.
BROWSER | DOWNLOAD LOCATION |
Chrome | http://chromedriver.chromium.org/downloads |
Firefox | https://github.com/mozilla/geckodriver/releases |
Opera | https://github.com/operasoftware/operachromiumdriver/releases |
Microsoft Edge | https://blogs.windows.com/msedgedev/2015/07/23/bringing-automated-testing-to-microsoft-edge-through-webdriver/ |
Internet Explorer | https://github.com/SeleniumHQ/selenium/wiki/InternetExplorerDriver |
The client-side and server-side interact with each other via a communication protocol.
For versions earlier than Selenium 4, the JSON Wire Protocol was used to communicate between the client and the server. It consists of the REST API that sends requests from the client to the server (browser’s native API) via HTTP.
From Selenium 4, the JSON Wire Protocol replaces the WebDriver W3C Protocol, enabling direct communication between the Selenium client libraries and the target browser. As the WebDriver and web browser use the same protocol, so encoding, and decoding API requests are no longer required, making the test cases more stable.
Installation and Setup: How to use Selenium with Java?
To start your automation testing journey using Selenium with Java, the first step is to install and configure Selenium onto your local system. In this section of this article on Selenium with Java, I will guide you through the installation process step by step. You will also learn how to create a basic Selenium with Java project setup.
Installation
The installation process consists of the following steps.
- Install JDK.
- Install Eclipse IDE.
- Install Selenium WebDriver and Language Bindings.
- Install Browser Drivers (Optional).
Install JDK
Let us start with the Java Development Kit (JDK) installation. The JDK includes JRE (Java Runtime Environment), used to write and run Java code. You can download JDK from any of the below options.
Once the installation is complete, set the environment variables. The steps are as follows:
- Search for environment variables, then click on the search result that says Edit the system environment variables.
- Click on Environment Variables.
- Click New under System variables.
- In the Variable name field, enter either
- JAVA_HOME, if you have installed the Java Development Kit (JDK).
- JRE_HOME, if you have installed the Java Runtime Environment (JRE).
- In the Variable value field, provide your JDK or JRE installation path.
- Click OK and then Apply Changes.
The environment variable setup is now complete. Open the command prompt and run the command java -version
to verify that Java has been successfully installed in your system.
Install Eclipse IDE
Next, we need to install an IDE (Integrated Development Environment). An IDE is a platform where developers can write and run the code. I will be using the Eclipse IDE for Java Developers for this demo. You can download the latest version from the Eclipse Downloads Page.
Once the installer file is downloaded, complete the installation process. Alternatively, you can also use any other popular IDE like Jetbrains Webstorm, IntelliJ IDEA, etc.
Install Selenium WebDriver and Language Bindings
Download the Selenium Client Library for Java from the Selenium Downloads Page. The download comes as a ZIP file. Extract the contents (JAR files) and store them in a directory.
We are downloading client drivers for Selenium 4. Please check out Previous Releases for working with Selenium 3 or older versions.
Install Browser Drivers (Optional)
Finally, if you are running your test scripts on your local system, it is mandatory to have its respective browser driver for automating a browser. You can download the drivers for the browsers of your choice from the Selenium Ecosystem Page.
However, you can skip this step using a cloud Selenium Grid.
With the installation process complete, let us move on to the project setup.
How to Create a Selenium With Java Project in Eclipse?
We need to have a project set up for writing and storing our test cases. You can follow the below-mentioned steps to create a new Selenium with Java project in Eclipse.
- Launch Eclipse
- Create a workspace.
- Create a new Selenium with Java project. Go to File > New > Java Project. Name the project.
- A new pop-up window will appear. Enter the following details: project name, location to save the project, and execution JRE. Once done, click Finish.
- Add Selenium API JAR files to the Java project by following the below-mentioned steps:
- Right-click on the project and select Properties.
- Select Java Build Path.
- Under the Libraries section, click on Add External JARs, which gets enabled upon opting for Classpath.
- Add the Selenium Java Client JARS. Navigate to the folder where you downloaded and extracted the JAR files.
- Once all the JAR files are added, click Apply and Close.
A workspace will be a place where you will be storing all your projects. You can create as many workspaces as required.
The project is now created.
With our project configured by Selenium with Java, we are ready to write and run our first test script in Selenium.
To perform automated testing using Selenium with Java, you can also leverage Maven. Maven is one of the popular Java build tools that relies on POM.xml. If you are new to Maven, check out this Selenium Maven tutorial, which guides you through writing and running Selenium projects with Maven.
Demo: Running Test Using Selenium With Java on Local
It is time to hit practicals! In this section of this article on Selenium with Java, you will learn to write your first test case using Selenium with Java on the local grid like LambdaTest.

package LambdaTest; import io.github.bonigarcia.wdm.WebDriverManager; import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import org.testng.annotations.AfterTest; import org.testng.annotations.BeforeTest; import org.testng.annotations.Listeners; import org.testng.annotations.Test; public class FirstTestScriptUsingWebDriver { public static WebDriver driver = null; @BeforeTest public void setUp() throws Exception { WebDriverManager.chromedriver().setup(); driver=new ChromeDriver(); } @Test public void firstTestCase() { try { System.out.println("Launching LambdaTest Sign In Page"); driver.get("https://accounts.lambdatest.com/register"); WebElement pageHeader= driver.findElement(By.xpath("//a[text()='Sign In']")); pageHeader.click(); System.out.println("Clicked on the Sign In Button."); } catch (Exception e) { } } @AfterTest public void closeBrowser() { driver.close(); System.out.println("The driver has been closed."); } } |
To import the required dependencies, you can use the below pom.xml file.
Test Execution
To run the above test case using Selenium with Java on a local grid, you can use the below testng.xml file:
1 2 3 4 5 6 7 8 9 10 |
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite name="FirstTestScriptUsingWebDriverSuite"> <test name="FirstTestScriptUsingWebDriver" > <classes> <class name="LambdaTest.FirstTestScriptUsingWebDriver" > </class> </classes> </test> </suite> |
Code Walkthrough
Here is the code walkthrough of the executed test on a local grid using Selenium with Java.
@BeforeTest annotation is a TestNG Annotation that helps execute a block of statements every time before any Test Method executes. So, we can use this annotation to maintain a preset for every test method, like launching browser, URL, and login, based on your requirements.
WebDriverManager in Selenium is an open-source Java library. It helps carry out the driver exe path setup for all browsers like Chrome, Edge, and Firefox in a single line. Here WebDriverManager.ChromeDriver.setup initializes the latest Chrome browser installed in the system. However, even initializing the version of the browser is also possible.
@Test is one of the more important TestNG Annotations, which defines a standard Java method as a test method. The try and catch block helps to capture any runtime exception and helps to handle the way developers want to end that execution.
The driver.get help to launch the required URL. Here, the required element, the Sign In link, is identified using XPath, a tag titled Sign In.
Each WebElement can be interacted with based on the element type, here as this element is a link, triggering a click event.
System.out.println in Java helps print messages on the console.
@AfterTest is another TestNG Annotation that executes the statements after every Test Annotation method executes. We can write statements that help tear down the process, like closing files and browsers.
The driver.close() method closes the current active browser launched by WebDriver. If multiple browsers exist, use driver.quit() to close all the sessions.
To achieve comprehensive browser coverage for Selenium Java testing, you may come across various challenges. These challenges often revolve around scalability issues and infrastructure limitations, including the availability of secure, enterprise-grade testing labs that meet all requirements and the recurring investment required to maintain and upgrade testing infrastructure.
A widely supported automation testing strategy to overcome these challenges is moving testing to the cloud. Through cloud testing, developers and testers can perform web testing across different browsers and hosted in the cloud infrastructure. By adopting a cloud-based testing approach, the need to maintain internal infrastructure is eliminated.
In addition, scalability issues associated with an on-premises test infrastructure that spans the spectrum of browsers, their different versions, and operating systems are effectively addressed. This approach is not only more efficient, but also proves to be cost-effective.
AI-powered test orchestration and execution platforms like LambdaTest provide an online Selenium Grid to perform Java automation testing on over 3000 real browsers and operating systems. The platform offers parallel testing in Selenium that improves the scalability of automated tests and reduces test execution time with simple setup and minimal configurations.
Demo: Running Test Using Selenium With Java on Cloud
In this section on the blog on Selenium with Java, we will run tests on the cloud using the TestNG framework. For this, we will use the LambdaTest Sign up page for demonstration purposes.

Code Walkthrough
Shown below is the code walkthrough of the executed test on a cloud grid using Selenium with Java.
The RemoteWebDriver class is used to execute test scripts through the RemoteWebDriver server on a remote machine.
To run the tests on the LambdaTest cloud Selenium Grid, you need to populate the corresponding username and access key values.
To set the necessary capabilities of browser name, version, platform, etc., you can use the LambdaTest Desired Capabilities Generator.
The remaining implementation will remain unchanged, as the only implementation that has changed is migrating from a local Selenium Grid to a cloud Selenium Grid.
Test Execution
Log on to LambdaTest Web Automation Dashboard to check the status of the test execution on LambdaTest.
If you are working on an actual project using Selenium with Java, you will need to write, run, and maintain hundreds of test cases. Each testing cycle will demand you to execute your test cases on multiple platforms and devices to ensure that the web application behaves as expected under various conditions and to ensure product quality before going live. It becomes highly desirable to reduce the overall test execution time, and one way to achieve it is through parallel testing.
In the next section of this tutorial on Selenium with Java, we will look at how to run parallel tests using a cloud grid like LambdaTest.
Demo: Running Parallel Tests in Selenium With Java
Parallel testing is a test execution strategy where the tests are run in parallel to reduce overall test execution time. Parallel testing was introduced to replace the traditional approach of sequential testing. As the name suggests, tests are executed sequentially, which is more time-consuming.
In the previous section, you learned how to write and run a test case sequentially using Selenium with Java. Now, I will walk you through how to run tests in parallel on a cloud-based Selenium Grid using the TestNG framework.
TestNG is a prominent open-source test automation framework for Java, where NG stands for ‘Next Generation.’ TestNG is widely adopted by Selenium users because of its features and feasibility. Running Selenium with Java tests alone comes with numerous limitations. However, TestNG introduces an entire set of new features, making it powerful and beneficial.
A few critical features of TestNG are listed below:
- Easy report generation in desirable formats. Now, it is easier to analyze how many test cases passed and how many failed during each test run.
- Supports parallel testing. Multiple test cases can be run simultaneously, reducing the overall test execution time.
- Possible to group test cases in TestNG effortlessly.
- TestNG annotations like @Test, @BeforeTest, @AfterTest, etc., are supported.
- Easy to integrate with tools like Maven, Jenkins, etc.
Parallel Test Execution in Selenium With Java on Cloud
One of the key advantages of adopting the TestNG automation framework is that it supports parallel test execution. Automation testing tools like TestNG allow you to run tests in parallel or multithreaded mode by utilizing the multi-threading concept of Java.
Multi-threading is the process of executing multiple threads simultaneously without any dependence on each other. This means the threads are executed in isolation, so exceptions occurring on one thread won’t affect the others. Multi-threading helps efficiently utilize the CPU by greatly reducing idle time. In TestNG, we enable parallel testing by making the required changes in the configuration file – TestNG XML file.
TestNG XML is the test suite configuration file in TestNG, which helps customize the execution of tests. It also allows you to run a single test file over numerous parameter combinations and specified values. A simple TestNG XML file looks like this.
1 2 3 4 5 6 7 8 9 |
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd"> <suite name="Regression Test Suite"> <test name="Sanity Tests"> <classes> <class name="SanityTest" /> </classes> </test> <!-- Test --> </suite> <!-- Suite --> |
To perform parallel testing using Selenium with Java, we will leverage the online Selenium Grid and run it parallelly across three different browsers.
For this demo on executing parallel tests using Selenium with Java, we will clone the LambdaTest Java TestNG GitHub repository and execute our test case parallelly on different browsers (Chrome, Safari, and Firefox) using the online Selenium Grid provided by LambdaTest.

String enteredText = driver.findElementByXPath("/html/body/div/div/div/ul/li[6]/span").getText(); if (enteredText.equals("Yey, Let's add it to list")) { status = true; } } catch (Exception e) { System.out.println(e.getMessage()); } } @AfterClass public void tearDown() throws Exception { if (driver != null) { ((JavascriptExecutor) driver).executeScript("lambda-status=" + status); driver.quit(); } } } |
Code Walkthrough
Here is the code walkthrough of the parallel tests executed using Selenium with Java.
These are the necessary imports for Selenium WebDriver, TestNG, and other related classes.
The code line below declares a class named TestNGTodo.
These are member variables used in the class, including credentials, Selenium WebDriver instance, grid URL, and a status flag.
This method is annotated with @BeforeClass, meaning it will run before any test method in the class. It sets up a ChromeOptions instance and configures it with the desired capabilities.
Then, it creates a RemoteWebDriver instance by connecting to the LambdaTest grid using the provided username, access key, and grid URL.
This method is annotated with @Test, indicating it is a test case.
- It navigates to a LambdaTest ToDo app.
- Mark the first two items as done.
- Add a new item to the list.
- Display the count of pending items.
This method is annotated with @AfterClass, indicating it will run after all test methods in the class. If the WebDriver instance is not null, it sets the lambda-status using JavaScript and quits the driver.
Here is a TestNG XML file that will be used to run the tests in parallel.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite thread-count="3" name="LambaTestSuite" parallel="tests"> <test name="WIN8TEST"> <parameter name="browser" value="firefox"/> <parameter name="version" value="120.0"/> <parameter name="platform" value="WIN8"/> <classes> <class name="LambdaTest.TestNGToDo"/> </classes> </test> <!-- Test --> <test name="WIN10TEST"> <parameter name="browser" value="chrome"/> <parameter name="version" value="121.0"/> <parameter name="platform" value="WIN10"/> <classes> <class name="LambdaTest.TestNGToDo"/> </classes> </test> <!-- Test --> <test name="MACTEST"> <parameter name="browser" value="safari"/> <parameter name="version" value="11.0"/> <parameter name="platform" value="macos 10.13"/> <classes> <class name="LambdaTest.TestNGToDo"/> </classes> </test> <!-- Test --> </suite> |
To trigger parallel execution, we need to set the parallel attribute. This attribute accepts four values:
- classes– to run all test cases present inside classes in the XML in parallel mode.
- methods – to run all methods with @Test annotation in parallel mode.
- tests – to run all test cases present inside the tag in the XML in parallel mode.
- instances – to run all test cases in the same instance in parallel mode.
We can also set the number of threads we wish to allocate during the execution using the thread-count attribute. The default value of thread count in TestNG is 5.
1 |
<suite thread-count="3" name="LambaTestSuite" parallel="tests"> |
To run the tests for the cloned repository, run the following command.
1 |
mvn test -D suite=parallel.xml |
Now, go to your LambdaTest Web Automation Dashboard to see your parallel test results.

Best Practices for Selenium Java Testing
Through Selenium Java automation testing, we aim to reduce the labor of manual testing, speed up the execution, detect maximum bugs early, achieve better coverage, and accelerate time to market.
However, writing a stable and reliant test case can be challenging due to factors like test flakiness, incorrect testing approach, etc. This is where HyperExecute, an end-to-end test orchestration cloud by LambdaTest, comes into the picture, eliminating these factors and cutting down on test execution times. This allows businesses to test code and fix issues much quicker and achieve an accelerated market time.
In this section of this article on Selenium with Java, let us discuss some of the best practices recommended by the Selenium community.
- Planning and Designing Test Cases Beforehand
- Implementing Page Object Model
- Choosing the Best-Suited Locators
- Implement Logging and Reporting
- Incorporating Wait Commands
- Auto-Healing: Auto-healing, when used for Selenium Java testing, mitigates synchronization issues by automatically adapting to dynamic changes in web elements, such as loading times or AJAX requests. Auto-healing in Selenium dynamically adjusts wait times and ensures that test scripts execute seamlessly even when there are delays or changes in the web page.
By intelligently handling timing-related challenges, auto-healing promotes stability in test automation, reducing the likelihood of flaky tests caused by synchronization issues. Selenium’s auto-healing capabilities enable scripts to adapt to varying conditions, maintaining synchronization between the test script and the application under test.
Before getting started with writing any automation tests, it is recommended that the QA teams invest time in creating a proper test plan.
However, to ensure foolproof testing of the application, QAs should come up with all possible logical scenarios and create maximum test cases based on the end-user perspective.
When a UI change occurs, the Selenium locators may also change, and we are required to update the modified locators in all the test scripts consuming it. But, as the application complexity increases and UI changes become more frequent, creating and maintaining test cases becomes tiresome. The Page Object Model (POM) is a popular design pattern in Selenium Java automation testing, which helps enhance test maintenance and reduce code duplication.
In the Page Object Model, all the web elements, actions, and validations happening on each web page are wrapped into a class file called Page Object. The POM allows a clean separation between test and page-specific codes such as locators and layouts.
Due to the centralized nature of the page-specific code, they can be reused throughout the test cases, reducing code duplication. Also, in case of any UI changes, the fix needs to be done only on the related Page Objects, not on dependent test cases, making code maintenance easier.
While writing automation test scripts, a lot of time is spent locating the web elements. Selenium offers us multiple strategies to locate a web element, such as ID, Name, Link Text, XPath, CSS Selector, DOM Locator, etc.
However, some web locators are more brittle than others. As the UI implementation is prone to frequent changes, we must be cautious in choosing the right web locators, which will minimize the impact of UI code changes in the automation tests. If available, opt for unique locators like ID and Name, which are easy to find and more reliable as they are less prone to change.
As the test suite becomes extensive, locating the failed test case and debugging becomes challenging. In these cases, reporting and logging practices can act as huge saviors.
The test report is a document that contains all the information about a particular test run, including the number of test cases passed, the number of test cases failed, the total time taken, errors with a snapshot, etc. Even though default Selenium does not come with reporting, you can implement it by leveraging test automation frameworks like TestNG.
The web browsers take some time to load the web page contents. The time taken for page load depends on many external factors like network speed, server issues, machine capabilities, etc. To tackle this, testers need to add some delay into the code so that the web element will be loaded and available before any action is performed.
In Java, testers often achieve this delay using Thread.sleep(). However, this is not the recommended practice. As the name implies, when the Thread.sleep() method is called, the thread goes to sleep for the specified amount of time and does absolutely nothing to pause the automation script. After the time is over, it executes the next line of code.
In real-time, we won’t be able to predict the exact time it would take for the page load as it depends on many external factors. Sometimes, the page may load quickly, lowering the test execution speed due to the remaining unnecessary delay caused by sleep().
And sometimes, it may take longer than the specified time, causing the test to fail as the element was not fully loaded. As a better and more efficient alternative, use the implicit wait and explicit wait commands provided by Selenium instead of the sleep method.
Watch this video to learn what are waits in Selenium and how to handle them using different methods like hard-coded pauses and combining explicit waits with different design patterns.
Cloud-based testing platforms like LambdaTest also offer a SmartWait feature that lets you handle challenges associated with waits.
LambdaTest SmartWait runs a series of “actionability checks” on webpage elements before executing any actions. These checks include verifying elements for visibility, presence, and interactability, ensuring they are ready for the intended action, such as clicking or typing.
