SOAtest Versus SoapUI

Modern composite applications are aggregating and consuming private, partner, and public APIs at a staggering pace in order to achieve business goals. As applications grow increasingly interdependent, the security, functionality, and performance must be verified.

The success of an end-to-end transaction depends upon all the parts working flawlessly all the time; even small glitches from a popular API can singlehandedly choke thousands of transactions.

Ensuring API integrity with an enterprise-level solution/tool has become a vital part of the quality assurance (QA) process. In this post we will compare two widely used tools: SoapUI and SOAtest.


SoapUI is an API testing application and framework for SOA (service-orientated architectures) and REST (representational state transfers). Its functionality covers much more than only API testing — with this app you can do web service inspection, invoking, development, simulation and mocking, functional testing, and load and compliance testing. It’s possible to create test cases using graphical user interfaces or in an embedded fashion with either Apache Ant or Apache Maven.

SoapUI has two versions — open source and a commercial version. The pro version includes more functionalities like test debugging, data-driven testing, test coverage among others.

SOAtest is a tool which allows users to verify all aspects of a web service, from WSDL validation, to functional testing of the client and servers and performance testing. SOAtest addresses key web service issues such as interoperability, security, change management, and scalability. The user is able to simulate the behavior of dependencies using a virtualization service and environment manager browser-based interface.

You can request a trial version and purchase a license afterwards, but there is no free version like SoapUI.

Our analysis


  • Free version.
  • We found it to be an excellent tool to get started with web service testing.
  • SoapUI’s intuitive and interactive user interface makes web service functional and performance testing a cake walk.
  • Once you are familiar with the tool, it is extremely easy to learn more complex tasks, like creating groovy scripts to automate the testing.


  • Better documentation and customer support.
  • Broad native support for platforms and technologies.
  • Broad protocol support (REST, JSON, PoX, SOAP, TIBCO…).
  • It can be integrated with Parasoft Environment Manager, HP ALM Center, Rational TestManager, Microsoft VSTS, and other commercial or internally-built frameworks to manage tests and execution results.

Having identified the differences and the strengths of the two tools, we encourage teams to evaluate their options and decide which vendor will best meet their business needs.
