How to Hit Your Restful Web Service Using Jmeter – Perform a Simple Load Test

Representational State Transfer (REST) has gained widespread acceptance across the Web as a simpler alternative to SOAP- and Web Services Description Language (WSDL)-based Web services. Key evidence of this shift in interface design is the adoption of REST by mainstream Web 2.0 service providers—including Yahoo, Google, and Facebook—who have deprecated or passed on SOAP and WSDL-based interfaces in favor of an easier-to-use, resource-oriented model to expose their services. Sometimes you have to test your RESTFul web service. You may have couple of options:

• Hit your WebService using single URL
• Use JMeter and hit WebService in loop. This test also performs some Simple Load Test.

Here in this example I’ll explain you on how Create Simple “Hello World” WebService and hit the same WebService using JMeter. Action Summary:

1. Pre-Requisite: Implement this RESTFul service completely. Deploy and Run Application. Let me know if you see any issue with it.
2. Create simple Java class: CrunchifyJMeterTest.java (Service which we will hit using JMeter).
3. Redeploy the Same Application on Apache Tomcat Web Server.
4. Run JMeter and Open .jmx file
5. Run and Analyse your test

Step1: Pre-Requisite: Implement this RESTFul service completely. Deploy and Run Application. Let me know if you see any issue with it. Step2: CrunchifyJMeterTest.java File

package com.crunchify.restjersey;

import java.io.FileNotFoundException;
import java.io.IOException;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

/**
 * @author Crunchify.com
 * 
 */

@Path("/index")
public class CrunchifyJMeterTest {
	@GET
	@Produces("text/html")
	public String checkECV() throws InterruptedException, FileNotFoundException, IOException {
		String result = "Hey This is Crunchify's JMeter Test...";

		System.out.println(result);
		Thread.sleep(1000);
		return result;
	}
}

You should see below Eclipse Directory Structure: Step 3: Redeploy the same CrunchifyRESTJerseyExample Project on Tomcat. Test it out your REST Service: URL: http://localhost:8080/CrunchifyRESTJerseyExample/crunchify/index/ Step 4.1: Copy below Code to file and save it as Crunchify-JMeter-Test.jmx.

Step 4.2: Run JMeter and File -> Open (Crunchify-JMeter-Test.jmx)

Step 5.1: Make sure below parameters are correct

Step 5.2: Analyse your Test Result.

There are number of other ways you can change your test parameters. Play with it and let me know how it goes. Feel free to let me know if you see any issue with this.
