如何配置Spring STS运行Selenium测试类？

Question

I'm using Spring STS (3.7) to develop an MVC application. I'm attempting to run a simple Selenium test using an example I've read in a book. I'm receiving a 'ClassNotFoundException' when I run the JUnit test. What's odd is that class that's not found is the test class itself: 'UIHomeTest'. I've verified that I have JUnit, Hamcrest and Selenium on the classpath. I've tried adding the JUnit library to the run configuration. Here is the code for the test class:

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebDriverBackedSelenium;
import org.openqa.selenium.firefox.FirefoxDriver;

import static org.junit.Assert.assertEquals;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.thoughtworks.selenium.SeleneseTestBase;

public class UIHomeTest {

private WebDriver browser;


private static final String HOME_URL = "http://localhost:8080/";

@Before
public void setUp() throws Exception {

    WebDriver driver = new FirefoxDriver();

}


@Test
public void testHomePage()
{

    browser.get(HOME_URL);

    assertEquals("Home", browser.findElement(By.id("title")).getAttribute("value"));
}

@After
public void tearDown() throws Exception
{
    browser.close();
}

}

Here is the error:

Class not found org.test.ui.UIHomeTest
java.lang.ClassNotFoundException: org.test.ui.UIHomeTest
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)

I've been able to run a non-Selenium JUnit test class inside of Spring STS before. Can anyone help me properly configure Spring STS to run Selenium test classes? Thanks.

On observing the imports and selenium code i found there are few not required imports used like import org.openqa.selenium.WebDriverBackedSelenium; import com.thoughtworks.selenium.SeleneseTestBase; and also not used or initiated driver object. below is the complete code which works fine for me.

com.tesngtraining; is my package. If you are downloaded java specific selenium jars then please include all jars which are in different folders in build path or download standalone selenium jar file and give it in build path.

 package com.tesngtraining;

import static org.junit.Assert.*;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class TestingJunit {

private WebDriver browser;


private static final String HOME_URL = "http://localhost:8080/";

@Before
public void setUp() throws Exception {

    browser = new FirefoxDriver();

}


@Test
public void testHomePage()
{

    browser.get(HOME_URL);

    assertEquals("Home", browser.findElement(By.id("title")).getAttribute("value"));
}

@After
public void tearDown() throws Exception
{
    browser.close();
}

}
