SoapUI is the world's most widely-used automated testing tool for SOAP and REST APIs. Write, run, integrate, and automate advanced API Tests with ease. The SOAP/XML-RPC Request sampler is used to send a SOAP or an XML-RPC request to a webservice. This sampler creates an HTTP POST request(as SOAP is based POST method) with the request body specified in the 'SOAP/XML-RPC Data' field.

SOAP is a messaging protocol specification for exchanging structured information in the implementation of web services. Its purpose is to induce extensibility, neutrality, and independence.
It uses XML Information Set for its message format and relies on application layer protocols.SOAP is used in a variety of messaging systems. It is delivered via a variety of transport protocols and the initial focus of SOAP is remote procedure calls transported via HTTP.Many applications run on web services in today’s world. Some of them run on SOAP services, some of them on RESTFUL services which support the JSON messaging format. That’s why performing a load test on these messaging protocols is crucial.We’ll explain how to test these kinds of web services via, open source, Apache JMeter testing tool. We’ll use a simple as an example. You can do simple Add, Subtract, Multiply and Divide operations. Create Your First Service CallCreate a Thread Group and Add an HTTP sampler as a child element to it.In this HTTP Sampler, you have to fill some fields;.
The protocol must be filled out to specify if it’s an HTTPS or HTTP. The server name must be filled out with the IP address or the domain name. A method is the most crucial one. You have many options. You need to know which method you are able to run on that web services. The method can be POST, GET, PUT, DELETE, etc. The path must be filled out to specify the endpoint of the web services.Note: It would be the best practice to separate the server name and path from each other.
In case there’s any change in the test environment, server name may change but the method is likely to stay as the same. Implement a GET RequestSend a GET request to get operation supported by your SOAP web services.
Fill the path as calculator.asmx?WSDL ( web services description language). This is the first web service call.Add a View Results Tree Listener into your test to analyze the results.Run your test and you will receive a response from the web service. If you take a look at the response, you’ll be able to see the operations name and parameters to send to these services. In this example, Add is an operation and it takes two integer parameters with intA and intB as variables name.Implement a POST RequestLet’s implement a POST request to one of the supported operations.Change the Path to /calculator.asmx and send below payload with it as seen in the picture: 205Implement the other services by following the first example. Now you’re ready to go.Note: There might be some cases where you need to specify headers to your web services. Header refers to supplemental data placed at the beginning of a block of data being stored or transmitted like content type, HTTP version, user agent, etc. In case you have such a requirement, just add an HTTP Header Manager to your sampler as follows.
Content will change according to your web services.Run your test once again and see the results flow like a charm.Happy load testing!
What is WebService?Web Services is the mechanism or the medium of communication through which two applications / machines will exchange the data irrespective of their underline architecture and the technology. Why is WebService Needed?In general, software applications are developed to be consumed by the human beings, where a person sends a request to a software service which in-turn returns a response in human readable format.In the modern era of technology if you want to build a software application you don't need to build each and everything from scratch. There are lots of readymade services available which you can plug into your application and you can start providing those services in your application.For example you want to display weather forecast information you don't need to collect, process and render the data in your application. WSDL describes all the operations offered by the particular web service in the XML format.
It also defines how the services can be called, i.e what input value we have to provide and what will be the format of the response it is going to generate for each kind of service. What is Web Service Testing?Web Services Testing is testing of Web services and its Protocols like SOAP & REST. To test a Webservice you can.
Test Manually. Create your own Automation Code. Use an off-the shelf automation tool like SoapUI.WebService Testing involves following steps -. Understand the WSDL file. Determine the operations that particular web service provides. Determine the XML request format which we need to send. Determine the response XML format.
Using a tool or writing code to send request and validate the responseSuppose we want to test a WebService which provides Currency Conversion Facility. It will the current conversion rates between the different countries currency. This service we can use in our applications to convert the values from one currency to the other currency.Now lets look at above steps Step 1 to 4: Understading WSDL and determining operations & XML formatsCurrency Convertor WSDL file can be seen @ which will give the information about the Currency Convertor web service methods which it will support, the parameter which we need pass and the type of parameters etcStep 5: Using a tool or writing code to send request and validate the responseThere are lots of tools available to test web services. SoapUI is one of the popular tool which will help us to test the web services. In fact you can use the any programing language which is capable of sending the XML request to the web service provider application over the http and able to parse and validate the response XML against the expected result.
In our case, we will test the WebService. Using Java. Using SoapUIPART 1) WebService Testing Using Apache Axis2 API (Java).Generally web service takes the request and sends the response in the XML format.Apache Axis2 API project is aimplementation API, which will be used to create the Web services for both server side (service provider) and client side (service consumer).Axis2 is capable of sending SOAP messages and Receives & Processes the SOAP messages. We can write a small Java program using the API to create the web service. Axis2 will generate the WSDL from Java program which will be used to communicate the services offered by the web service.
