Creating a Selenium demo involves setting up a simple Selenium WebDriver project and writing a basic test script to interact with a web page. Below, I’ll outline the steps to create a Selenium demo using Java as an example. You can adapt this for other programming languages as well.

Step 1: Set Up Your Development Environment

• Install Java Development Kit (JDK): If not already installed, download and install the latest JDK from the Oracle or OpenJDK website.

• Install an Integrated Development Environment (IDE): Choose an IDE for Java development, such as IntelliJ IDEA, Eclipse, or Visual Studio Code.

• Set Up a Build Tool: Use a build tool like Maven or Gradle to manage dependencies and build your Selenium project. You can create a Maven or Gradle project from your IDE.

Step 2: Create a Selenium Project

• Create a new Java project in your chosen IDE and configure it as a Maven or Gradle project if you haven’t already.

Step 3: Add Selenium WebDriver Dependencies

• In your project’s pom.xml (for Maven) or build.gradle (for Gradle), add dependencies for Selenium WebDriver. Here’s an example for Maven:

  xmlCopy code

  <dependencies> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>3.141.59</version> </dependency> </dependencies>

  Be sure to use the latest version of Selenium WebDriver.

Step 4: Create a Selenium Test Script

• Create a Java class to write your Selenium test script. Here’s a simple example that opens a web page, interacts with an element, and performs a basic assertion:

  javaCopy code

  import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; public class SeleniumDemo { public static void main(String[] args) { // Set the path to your ChromeDriver executable System.setProperty("webdriver.chrome.driver", "path/to/chromedriver"); // Initialize the WebDriver (in this case, Chrome) WebDriver driver = new ChromeDriver(); // Navigate to a website driver.get("https://www.example.com"); // Find an element by its CSS selector WebElement element = driver.findElement(By.cssSelector("h1")); // Perform an action (e.g., get text) String text = element.getText(); // Perform an assertion assert text.equals("Example Domain"); // Close the browser driver.quit(); } }

  Make sure to replace "path/to/chromedriver" with the actual path to your ChromeDriver executable.

Step 5: Run the Selenium Test

• Execute your Selenium test script using your IDE’s built-in test runner or by running the Java class directly. The script will open a Chrome browser, navigate to “https://www.example.com,” and perform the specified actions and assertions.

Step 6: Review the Results

• After running the test, review the results to ensure that the Selenium script interacts correctly with the web page and that the assertions pass.
