Question 5:
What are the steps to create a simple WebDriver Script? Explain it with a code.
Creating a Simple WebDriver Script: A Step-by-Step Guide
Automating web tests using Selenium WebDriver has become a cornerstone for ensuring the quality and reliability of web applications. Whether you're a beginner or an experienced tester, creating a simple WebDriver script is the first step towards harnessing the power of Selenium for automated testing. In this blog, we'll walk you through the process of creating a basic WebDriver script using Java, one of the most popular programming languages for Selenium automation.
Step 1: Set Up Your Development Environment
Before diving into writing WebDriver scripts, ensure that you have the necessary tools and dependencies installed in your development environment. You'll need:
- Java Development Kit (JDK)
- Integrated Development Environment (IDE) such as IntelliJ IDEA or Eclipse
- Selenium WebDriver libraries
- Browser driver executable (e.g., ChromeDriver for Google Chrome)
Step 2: Create a New Java Project
Open your preferred IDE and create a new Java project. You can name it whatever you like. Once the project is created, add the Selenium WebDriver libraries to your project's build path. You can download the WebDriver libraries from the Selenium official website or use dependency management tools like Maven or Gradle.
Step 3: Write Your WebDriver Script
Now, it's time to write your first WebDriver script. Let's create a simple script that opens a browser, navigates to a webpage, and verifies the title of the page.
Java:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class SimpleWebDriverScript {
public static void main(String[] args) {
// Specify the path to the ChromeDriver executable
System.setProperty("webdriver.chrome.driver", "path\\to\\chromedriver.exe");
// Initialize ChromeDriver
WebDriver driver = new ChromeDriver();
// Navigate to the desired webpage
driver.get("https://www.example.com");
// Get and print the title of the webpage
String pageTitle = driver.getTitle();
System.out.println("Page Title: " + pageTitle);
// Close the browser
driver.quit();
}
}
In this script:
- We import the necessary WebDriver classes and the ChromeDriver class.
- We specify the path to the ChromeDriver executable using System.setProperty(). Replace "path/to/chromedriver.exe" with the actual path to your ChromeDriver executable.
- We initialize ChromeDriver by creating a new instance of the ChromeDriver class.
- We use the get() method to navigate to the desired webpage (in this case, "example.com").
- We use the getTitle() method to retrieve the title of the webpage and print it to the console.
- Finally, we call the quit() method to close the browser window and end the WebDriver session.
Step 4: Run Your WebDriver Script
After writing the script, save it and run it within your IDE. If everything is set up correctly, you should see the browser window open, navigate to the specified webpage, and print the title of the page to the console. Once the script execution is complete, the browser window will automatically close.
Output of Browser initiated with URL:
Console Output of Page Title:
