Change the title of a webpage in JUnit test with Selenium Web Driver

Question

I want to write an automated JUnit test script with Selenium Web Driver to load a Wikipedia page and then change the title of the page loaded.

import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;
import org.openqa.selenium.support.ui.WebDriverWait;



public class wikiTest {
  private WebDriver driver;
  private String baseUrl;
  private boolean acceptNextAlert = true;
  private StringBuffer verificationErrors = new StringBuffer();

  @Before
  public void setUp() throws Exception {
    driver = new FirefoxDriver();
    baseUrl = "https://www.wikipedia.org/";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }

  @Test
  public void testwiki() throws Exception {
      WebDriverWait wait;
    driver.get(baseUrl + "/");
    driver.findElement(By.id("searchInput")).clear();
    driver.findElement(By.id("searchInput")).sendKeys("fish anatomy");
    driver.findElement(By.name("go")).click();
    wait = new WebDriverWait(driver, 10);
    //driver.findElement(By.id("firstHeading")).click();

    /* in here I want to change the title of the page
    */

  }

  @After
  public void tearDown() throws Exception {
   // driver.quit();
    String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
      fail(verificationErrorString);
    }
  }

  private boolean isElementPresent(By by) {
    try {
      driver.findElement(by);
      return true;
    } catch (NoSuchElementException e) {
        e.printStackTrace();
      return false;
    }
  }

  private boolean isAlertPresent() {
    try {
      driver.switchTo().alert();
      return true;
    } catch (NoAlertPresentException e) {
      return false;
    }
  }

  private String closeAlertAndGetItsText() {
    try {
      Alert alert = driver.switchTo().alert();
      String alertText = alert.getText();
      if (acceptNextAlert) {
        alert.accept();
      } else {
        alert.dismiss();
      }
      return alertText;
    } finally {
      acceptNextAlert = true;
    }
  }
}

Any help is appreciated.

I'm not sure why you would ever want to do that, but one way is to simply execute some javascript.

import org.openqa.selenium.JavascriptExecutor;    

((JavascriptExecutor)driver).executeScript("document.title = 'new title'");

EDIT

Changing text on a webpage (as per the comments) is achievable with pretty much the same method. just execute some javascript. so, inside the quotes instead of document.title = 'new title' use document.getElementById('firstHeading').innerHTML = 'new text' or for modern browsers use textContent instead of innerHTML.
