Program: Assertion method Assert.assertNotSame() example.


Java Class: org.junit.Assert

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

Assert.assertNotSame() methods checks that two objects do not refer to the same object. If they do refer to the same object, an AssertionError is 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 MyAssertNotSameTest {

	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(){
		
		MyAssertNotSameTest msnt = new MyAssertNotSameTest();
		assertNotSame(msnt.getPropValue("key1"), msnt.getPropValue("key2"));
	}
}

Preemptive scheduling Vs Time slicing?
Preemptive scheduling: The highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence.

Time slicing: A task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based on priority and other factors.
