Selenium is one of the automation testing tools which is an open source tool. You can automate your web application using Selenium in various languages such as Java, Python, Javascript, C# etc.

Here i would like to explain how you can perform selenium automation testing with java. Below is the basic java code for automation testing and its explanation.

package newproject;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
//comment the above line and uncomment below line to use Chrome
public class PG1 {
    public static void main(String[] args) {
        // declaration and instantiation of objects/variables
		WebDriver driver = new FirefoxDriver();
		//comment the above 2 lines and uncomment below 2 lines to use Chrome
		//WebDriver driver = new ChromeDriver();
        String baseUrl = "";
        String expectedTitle = "Welcome: Mercury Tours";
        String actualTitle = "";
        // launch Fire fox and direct it to the Base URL
        // get the actual value of the title
        actualTitle = driver.getTitle();
         * compare the actual title of the page with the expected one and print
         * the result as "Passed" or "Failed"
        if (actualTitle.contentEquals(expectedTitle)){
            System.out.println("Test Passed!");
        } else {
            System.out.println("Test Failed");
        //close Fire fox

Explaining the code

Importing Packages

To get started, you need to import following two packages:

  1. org.openqa.selenium.*- contains the WebDriver class needed to instantiate a new browser loaded with a specific driver

  2. org.openqa.selenium.firefox.FirefoxDriver - contains the FirefoxDriver class needed to instantiate a Firefox-specific driver onto the browser instantiated by the WebDriver class

If your test needs more complicated actions such as accessing another class, taking browser screenshots, or manipulating external files, definitely you will need to import more packages.

Instantiating objects and variables

Normally, this is how a driver object is instantiated.

A FirefoxDriver class with no parameters means that the default Firefox profile will be launched by our Java program. The default Firefox profile is similar to launching Firefox in safe mode (no extensions are loaded).

For convenience, we saved the Base URL and the expected title as variables.

Launching a Browser Session

WebDriver's get() method is used to launch a new browser session and directs it to the URL that you specify as its parameter.

Get the Actual Page Title

The WebDriver class has the getTitle() method that is always used to obtain the page title of the currently loaded page.

Compare the Expected and Actual Values

This portion of the code simply uses a basic Java if-else structure to compare the actual title with the expected one.

Terminating a Browser Session

The "close()" method is used to close the browser window.

Terminating the Entire Program

If you use this command without closing all browser windows first, your whole Java program will end while leaving the browser window open.

You can run your java automation script on LambdaTest which is a cross browser testing tool. This would help you to record your automated browser video, get your test logs, show your errors and exceptions, run your test concurrently with different configurations such as different OS, browsers, browser versions and resolution.
