Web Service Performance Testing using Apache JMeter

In this blog post, we will see about Web Service Performance Testing using Apache Jmeter. It is very simple to test SOA web services using Jmeter. In your project, you get all the assets such as WSDL, Sample Request XML and Response XML, endpoint URLs etc.

But if you want to practice some sample web services at home, you need public web services. After lot of googling, I have found this website called http://www.webservicex.net/ which has numerous sample web services such as Stock, Currency, and Weather etc.

Now we will see how to performance test the web services using Apache Jmeter.

Follow below steps to create web service test plan in Jmeter:

  • Launch Jmeter
  • Add a Thread Group
  • Add a Loop Controller. I always prefer to add Loop controller, I pretend that as a default actions like in LoadRunner
  • Right Click on Loop Controller > Add > Sampler > WebService(SOAP) Request (DEPRECATED). You get web service sampler as shown below.

  • Enter the WSDL URL and click on Load WSDL. Now you can see Web Methods is showing the methods as below.

  •  Click on Configure. You could see the some of the fields will be automatically filled up as shown below.

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetQuote xmlns="http://www.webserviceX.NET/">
      <symbol>IBM</symbol>
    </GetQuote>
  </soap:Body>
</soap:Envelope>

Edit the string to company code e.g. INFY, IBM, APPL etc. You can parameterize if you wish.

  • Here is the complete test sampler.

  •  Add View Results Tree and click on Run. Response will be received as below.

  • Here is the SOAP/XML RPC Request Sampler:

TIP:

  • Always check Read SOAP Response in WebService(SOAP) Request (DEPRECATED) sampler, else you will not be able to see the response.
