How do I run JUnit tests from a Windows CMD window

Here is my JUnit test class: package com.bynarystudio.tests.storefront;

import java.util.List;

import org.junit.Assert;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;

import com.bynarystudio.tests.BaseWebTest;

public class SmokeTests extends BaseWebTest {

@Test
public void StoreFrontMegaNavTest(){
    webDriver.get(default_homepage);

    String source = webDriver.getPageSource();

    Assert.assertTrue(source.contains("some text"));    
}
}

How do I run this test from the command line? When I try to run it from inside its directory using

java -cp junit.textui.TestRunner SmokeTests.java

I get the following error

Could not find the main class: SmokeTests.java.  Program will exit.

I think this has to do with the fact that my classpath is not setup properly. But I have no idea because I'm brand new to Java. Coming from .NET, C#, and Visual Studio, the whole classpath thing makes no sense. Even though I have all my files correctly added to a project in Eclipse (I know because the test runs fine from inside Eclipse), it will absolutely not run or compile from the command line.

First of all you are mixing two things:

First you have to compile the project using javac command. As a result you will get set of .class files (not .java -> this is source code)
Then you can run the code using java command: java -cp classPath yourpackage.SmokeTests

where:

classPath - is the list of directories or jar files where your compiled classes are, if you jave multiple entries separate them using ";" (windows) or ":"(Linux)

so your classPath can be: -cp .;c:/jars/*;deps

which means your classpath will contain:
