jMeter - JMS Test Plan

In this chapter, we will learn how to write a simple test plan to test Java Messaging Service (JMS). JMS supports two types of messaging −

• Point-to-Point messaging − Queue messaging is generally used for transactions where the sender expects a response. Messaging systems are quite different from normal HTTP requests. In HTTP, a single user sends a request and gets a response.
• Topic messaging − Topic messages are commonly known as pub/sub messaging. Topic messaging is generally used in cases where a message is published by a producer and consumed by multiple subscribers.

Let us see a test example for each of these. The pre-requisites for testing JMS are −

• We use Apache ActiveMQ in the example. There are various JMS servers like IBM WebSphere MQ (formerly MQSeries), Tibco, etc. Download it from the binaries from the Apache ActiveMQ website.
• Unzip the archive, go to the decompressed directory, and run the following command from the command console to start the ActiveMQ server −

.\bin\activemq  start

You can verify if the ActiveMQ server has started by visiting the admin interface at the following address http://localhost:8161/admin/. If it asks for authentication, then enter the userid and password as admin. The screen is similar as shown below −

• Now copy the activemq-all-x.x.x.jar (XXX depending on the version) from the ActiveMQ unzipped directory to /home/manisha/apache-jmeter-2.9/lib.

With the above setup, let us build the test plan for −

• JMS Point-to-Point Test Plan
• JMS Topic Test Plan
