How to Test Web Service using SOAP UI?

Using SOAP UI, automated tests can be created for web services and Test Web Service using SOAP UI.

In this article, we will

• Create a SOAP project using SOAP UI
• Create Assertions in SOAP UI
• Build an automated test using SOAP UI

First, you need to install SOAP UI from the URL https://www.soapui.org/downloads/soapui.html.

Create a SOAP project:

Step 1: Open SOAP UI.

Step 2: Press Ctrl + N to create a new project.

Step 4: Enter the URL of WSDL in the field of Initial WSDL. The field Project Name will automatically get filled.

Step 5: Click on, OK. It will then create a new project.

Build a Test Suite, Test Case, and Test Step:

Step 1: Press Ctrl + T to create a new test suite.

Step 2: Click on, OK. Select the name of your Test Suite and press Ctrl + N to create a new Test Case.

Step 3: Click on, OK. Expand the Test Suite and Test Case. Right-click on the Test Step > Add Step > SOAP Request.

Step 4: Enter the name of the step and click on, OK.

Step 5: Select the option CustomerWebserviceSoap -> GetCustomers and click on OK.

Step 6: Again, click, OK.

Step 2: Click on the icon Add Assertion.

Step 3: Click Property Content > XPath Match. Enter the expression count(//Customer) and click on Save.

Extend your Test Case:

Step 1: Add a new Soap Request to the already available test cases.

Step 2: Change the request.

<soapenv:Envelope xmlns:soapenv="https://schemas.xmlsoap.org/soap/envelope/" xmlns:exam="https://www.example.com/">
   <soapenv:Header/>
   <soapenv:Body>
      <exam:CreateCustomer>
         <Name>Donald A. Hylton</Name>
         <Address>784 Better Street</Address>
         <City>Kansas City</City>
         <ZipCode>KS 66102</ZipCode>
      </exam:CreateCustomer>
   </soapenv:Body>
</soapenv:Envelope>

Step 3: Add a Contains Assertion and enter true.

Step 4: Right-click on the test case, Retrieve Customers. Select the option Clone Test Step. Change the Test Step name to Retrieve Customers 2 and click on OK.

Step 5: Open Test Step Retrieve Customers 2. Click on Assertions (2). Open XPath Match – Unknown. Change the Expected Result to 1+ and click on button Save.
