Basic TDD with Jersey Test Framework

Decided to do TDD on one of  my mobileTAO initiatives. I hope this may also help others who wish to learn TDD with Jersey test framework

1.Requirements

1. JDK 1.6
2. Eclipse Indigo
3. Jersey
4. Jersey Test Framework
5. Maven 3.0.4 (with m2eclipse plugin)

2. Create maven project

run
mvn archetype:generate -DgroupId=desired.group.id -DartifactId=desiredArtifactId -Darchetype.ArtifactId=maven-archetype-webapp -DinteractiveMode=false

run mvn eclipse:eclipse in order to support eclipse

 Import project to eclipse

3. Setting up Dependencies 

Add the jersey dependency to your pom.xml

	<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

4. Create the test 

We will now code our unit test. add the source code to src/test/java

	package org.qoutepad.test;
	import static org.junit.Assert.*;
	import com.sun.jersey.api.client.WebResource;
	import com.sun.jersey.test.framework.JerseyTest;
	import org.junit.Test;
	import org.qoutepad.rest.HelloJSTService;
	public class HelloJST extends JerseyTest {
	public HelloJST(){
	super(HelloJSTService.class.getPackage().getName());
	}
	@Test
	public void helloJSTTest(){
	WebResource resource = resource();
	String message = resource.path("helloJST").get(String.class);
	assertEquals("HelloJST", message);
	}
	}

5. Create rest service

	package org.qoutepad.rest;
	import javax.ws.rs.Path;
	import javax.ws.rs.GET;
	@Path("/helloJST")
	public class HelloJSTService {
	@GET
	public String getMessage(){
	return new String("HelloJST");
	}
	}
