Can you explain what the SoapUI tool is and what role it plays in web service testing?

SoapUI is a popular tool for functional testing of web services, especially SOAP and REST APIs. It allows creating, executing, and automating tests to verify the correctness of services, including checking requests, responses, headers, response times, and other parameters.

Main features of SoapUI:

• Creating test scenarios without programming (via a graphical interface).
• Support for various protocols (SOAP, REST, JMS, etc.).
• Ability to write scripts in Groovy to extend functionality.
• Security and load testing.

Example of usage: you create a test that sends a SOAP request to a web service and checks that the response contains the expected data. This helps ensure that the service works correctly after changes or updates.
