This is a simple implementation of Doc Tests for Java using Bean Shell. 

Doc Tests offer 4 main advantages:

* tests as example code in the documentation 
* tests that are very close to the code its testing
* no need for heavy test set-up
* tests will never get build and shipped to production


See this example class on how its used:

/**
 * This shows a simple use of Java Doc Test 
 *
 * % Example e = new Example()
 * 
 */
public class Example {
	
	/**
	 * @return the answer to life the universe and everything
	 * 
	 * % e.getAnswerToLifeUniverseEverything()
	 * > 42
	 */
	public int getAnswerToLifeUniverseEverything(){
		return 42;
	}
	
	/**
	 * @return adds 3 numbers
	 * 
	 * % e.add(1, 2, 3)
	 * > 6
	 * % e.add(1, 7, 3)
	 * > 11
	 * % e.add(21, 7, 14)
	 * > e.getAnswerToLifeUniverseEverything()
	 */
	public int add(int a, int b, int c){
		return a + b + c;
	}
	
	/**
	 * @return toString representation
	 * 
	 * % e.toString()
	 * > "Super Example Class"
	 */
	public String toString(){
		return "Super Example Class";
	}
	
}
