A few important functionalities of SOAP UI are as follows:

• It BUILDS a new project-based just on the web service WSDL link; it retrieves all method information and imports it automatically.
• It generates test cases from the web method request itself.
• It evaluates web techniques individually or in combination. It includes a very important feature that allows you to transmit data and arguments from one method to another. It allows you to PRESERVE data in variables so that it may be accessed by other methods.
• It allows you to use assertions to validate web method results; assertions may be WRITTEN in either XPATH or Xquery.
• It aids in the creation of various validations such as schema compliance, SOAP fault, response speed, and so on.
• It allows you to organise your test cases into test suites.
• It allows you to execute all of the test cases in a test suite and get fail/pass results for each one.
• It allows parameterization of test case request fields, allowing a test case to access various values from a table or database.
• It is POSSIBLE to create complicated validation scripts using Groovy.
• It has some load testing features for web services.
• It has various features to help with testing coverage and requirements management.
