HtmlUnitDriver Error: java.lang.NoClassDefFoundError: com/gargoylesoftware/htmlunit/WebWindowListener

I created a java class called htmlUnitTest to do a test with Selenium Headless Testing. The class basically goes to the google site and writes a text in the search box of the site, does the search and takes the page title and displays the title in the Eclipse console. When I run the test, Eclipse displays the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: com/gargoylesoftware/htmlunit/WebWindowListener at htmldriver.htmlUnitTest.main(htmlUnitTest.java:12) Caused by: java.lang.ClassNotFoundException: com.gargoylesoftware.htmlunit.WebWindowListener at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 1 more

The jar file I used to import the HtmlUnitDriver class for my project was: selenium-htmlunit-driver-2.52.0.jar.

Below is the Java code.

public class htmlUnitTest {

public static void main(String[] args) {

    WebDriver driver = new HtmlUnitDriver();
    driver.get("https://www.google.com.br/");

    WebElement ele = driver.findElement(By.name("q"));
    ele.sendKeys("Teste");
    ele.submit();

    System.out.println("Título da página: " +driver.getTitle());
    driver.quit();
}}

htmlUnitTestError

Solution

  • The HtmlUnitDriver is only a small wrapper around HtmlUnit itself. So you need all the dependencies of the selenium-htmlunit-driver also (in fact HtmlUnit with all the dependencies).
