SoapUI is a free open source, cross-platform API testing tool, mainly used to test Web services and Web APIs. The SoapUI testing tool’s functionality covers features like web service inspection, invoking, development, simulation, and mocking; and can automate functional, load, regression, and compliance testing. It has an inbuilt reporting tool and ‘export test results log’ provision.
Built entirely on Java Platform, SoapUI uses Java Swing for the user interface and is simple to install. Moreover, it offers support for standard protocols and technologies to test APIs. It supports third-party plugins and is easy to integrate with IDEs like NetBeans, Eclipse, and Maven. Developers can also build custom plugins using SoapUI APIs. The protocols supported by SoapUI can be represented as follows:
With a simple interface, SoapUI allows even the non-technical users to use the tool flawlessly. Let’s discuss some of the commonly used features of SOAP UI testing.
Functional testing – You don’t have to be a developer to write automated functional tests in SoapUI. It’s amazingly simple. With the SoapUI testing tool, testers can leverage the following features:
a. Drag and Drop Test Creation
b. Testing Complex Scenarios
c. Creating Custom Scripts
d. Multi-Environment Support
e. Asynchronous Testing Support
f. Test Debugging
Compliance Testing – SoapUI allows testers to validate the compliance tests and automate those test scripts.
Security testing –SoapUI testing tool supports security testing to ensure authorization and authenticity in request and response model of the Web services and Web APIs. In the context of security, following features can be leveraged by testers:
a. Cross -Site scripting scans
b. XML Bomb Scans for Stack Overflows
c. Scans to identify erratic service behavior
d. Database security via scans for potential SQL injections
Load Testing – It helps analyze the load that a web service or Web API can withhold before it breaks. For this type of testing, SoapUI testing tool supports the following features:
a. Real-time Interactive Distributed Load Testing
b. Drag and Drop Test Creation
c. Access to pre-built load strategies to test service performance
d. Performance Monitoring
e. Auto-generated and custom reporting
Regression Testing – This is conducted to analyze any malfunctioning within the web services when any new change has been introduced. Testers can execute test suites using SoapUI to find out if the existing functionalities are working as expected.
SoapUI can be integrated with a number of tools. Some of the popular ones are Maven, Hudson, JUnit and Apache Ant.
Despite the above advantages, there are a few drawbacks of the SoapUI testing tool:
a. SoapUI lacks adequate documentation when using advanced features.
b. Load Testing and workflow testing are not easy to perform in SoapUI.
c. Using SoapUI, memory consumption is a bit higher in concurrent testing.
Though SOAPUI is a widely used cross-platform open source testing tool for Web API or web services testing, it is not entirely free from drawbacks. However, with easy to use interface and enterprise-class features, it is here to stay for long. A professional version of SoapUI called SoapUI Pro is also available for advanced SOAP and REST API functional testing, and offers more features along with making test creation simpler.
For testers, this implies that learning this tool is vital for them to remain competitive in the market. However, to stay ahead of the game, testers need to continuously learn new and upcoming tools and skills, stay up-to-date and take relevant certifications. Happy learning!
