Program: Assertion method Assert.assertSame() example.


Java Class: org.junit.Assert

Assert class provides a set of assertion methods useful for writing tests.

Assert.assertSame() methods checks that two objects refer to the same object. If they are not the same, then an AssertionError will be thrown.


package com.java2novice.junit.tests;

import static org.junit.Assert.*;

import java.util.HashMap;
import java.util.Map;

import org.junit.Test;

public class MyAssertSameTest {

	public String getPropValue(final String key){
		Map appProps = new HashMap();
		appProps.put("key1", "value 1");
		appProps.put("key2", "value 2");
		appProps.put("key3", "value 3");
		return appProps.get(key);
	}
	
	@Test
	public void isSameReferenceTest(){
		
		MyAssertSameTest msnt = new MyAssertSameTest();
		assertSame(msnt.getPropValue("key1"), msnt.getPropValue("key1"));
	}
}

Difference between Enumeration and Iterator
The functionality of Enumeration and the Iterator are same. You can get remove() from Iterator to remove an element, while while Enumeration does not have remove() method. Using Enumeration you can only traverse and fetch the objects, where as using Iterator we can also add and remove the objects. So Iterator can be useful if you want to manipulate the list and Enumeration is for read-only access.
Famous Quotations
If you don’t make mistakes, you’re not working on hard enough problems. And that’s a big mistake.
