Can you tell us about your experience with the SOAP protocol for message exchange?

In the context of web service testing, I worked with the SOAP protocol for exchanging structured messages between the client and server. SOAP uses XML for message formatting and typically operates over HTTP.

In QA practice, I created and sent SOAP requests using tools such as SoapUI or Postman, checked the correctness of responses, validated XML schemas, and handled errors returned by the server.

An example of a simple SOAP request to invoke the getUser method:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:usr="http://example.com/user">
   <soapenv:Header/>
   <soapenv:Body>
      <usr:getUser>
         <usr:id>123</usr:id>
      </usr:getUser>
   </soapenv:Body>
</soapenv:Envelope>

Thus, experience with SOAP includes understanding message structure, the ability to formulate requests, and analyze responses for service testing automation.
