Example selenium webdriver code to click button/link/any kind of element using java

Example 1: 

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Test {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
WebDriver driver = new FirefoxDriver(); // launch the firefox browser
driver.get("http://www.google.com"); // Navigate to google.com
driver.findElement(By.name("q")).sendKeys("test"); // send 'test' value in google search textbox
driver.findElement(By.name("btnG")).click(); // click on google search button

}

}

Example 2: Using mouse action class in selenium

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;

public class Test {

/**
 * @param args
 */
public static void main(String[] args) {
// TODO Auto-generated method stub
WebDriver driver = new FirefoxDriver(); // launch the firefox browser
driver.get("http://www.google.com"); // Navigate to google.com
driver.findElement(By.name("q")).sendKeys("test"); // send 'test' value in google search textbox
Actions action = new Actions(driver);
  action.click(driver.findElement(By.name("btnG"))).build().perform(); // click on google search button

}

}

Example 3: Using JavascriptExecutor class in selenium

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.JavascriptExecutor;

public class Test {

/**
 * @param args
 */
public static void main(String[] args) {
// TODO Auto-generated method stub
WebDriver driver = new FirefoxDriver(); // launch the firefox browser
driver.get("http://www.google.com"); // Navigate to google.com
driver.findElement(By.name("q")).sendKeys("test"); // send 'test' value in google search textbox
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", driver.findElement(By.name("btnG"))); // click on google search button

}

}

Sample selenium code to launch web browsers(Chrome, InternetExplorer, Firefox) using java

Google Chrome:

1.     Download the chromedriver.exe file based on your browser version from this link     http://chromedriver.storage.googleapis.com/index.html. 
2. Once download completed copy the chromedriver.exe file and paste it in windows folder or you can set the environmental variables path to the location of chromedriver.exe(Ex location path like:D:\chromedriver.exe).
3. Download latest selenium server jar file from this link http://docs.seleniumhq.org/download/ and then add this jar into your project build path.
4. Below I have pasted my selenium code to launch the browser for your reference 

                     import org.openqa.selenium.WebDriver;

                     import org.openqa.selenium.chrome.ChromeDriver;

                    public class Test {

               public static void main(String[] args) {

             // TODO Auto-generated method stub

             WebDriver driver = new ChromeDriver(); // launch the browser

            driver.get("http://www.google.com"); // navigate to url

            }

                 }

InternetExplorer:

1.     Download the IEdriverserver.exe file based on your OS version(32bit/64bit) from this link     http://docs.seleniumhq.org/download/
2. Once download completed copy the IEdriverserver.exe file and paste it in windows folder or you can set the environmental variables path to the location of IEdriverserver.exe(Ex location path like:D:\IEdriverserver.exe).
3. Download latest selenium server jar file from this link http://docs.seleniumhq.org/download/ and then add this jar into your project build path.
4. Below I have pasted my selenium code to launch the browser for your reference 

                     import org.openqa.selenium.WebDriver;

                     import org.openqa.selenium.ie.InternetExplorerDriver;

                    public class Test {

               public static void main(String[] args) {

             // TODO Auto-generated method stub

             WebDriver driver = new InternetExplorerDriver(); // launch the browser

            driver.get("http://www.google.com"); // navigate to url

            }

                 }

Firefox:

1. Download latest selenium server jar file from this link http://docs.seleniumhq.org/download/ and then add this jar into your project build path.Note:New selenium jar supports all version of firefox browsers so better use latest selenium server jar.
2. Below I have pasted my selenium code to launch the browser for your reference 

                     import org.openqa.selenium.WebDriver;

                     import org.openqa.selenium.firefox.FirefoxDriver;

                    public class Test {

               public static void main(String[] args) {

             // TODO Auto-generated method stub

             WebDriver driver = new FirefoxDriver();// launch the browser

            driver.get("http://www.google.com"); // navigate to url

            }
