Over the past decade, Service Oriented Architecture (SOA) adoption has increased significantly. SOA is essentially a collection of services that communicate with each other. This communication could either involve simple data transfer or it could involve two or more services coordinating some activity. These services are connected together by web services. The web services provide a standard means of interoperability between software applications running on a range of platforms and frameworks using XML, Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL), and UDDI open standards over an internet protocol.
Service oriented architecture has great benefits. Test planning and test evaluation must be well architected while using SOA. Some of the challenges include:
Functionality Testing entails verifying conformance of the service behavior against the given service design
Integration Testingfocuses on the interactions between the services and interfaces to form a complete business transaction.
Integration testing can also be done by Web Service Mocking. It’s possible for us to start creating test for a Web Service the same time we start to develop the same Web Service. This means, when the real Web Service is ready for testing; we can already have the tests done. This can be extremely powerful and will make it possible to work according to Test Driven or Agile Methodologies.
Given that web services are designed to be re-used and consumed by multiple clients, it is critical to understand the performance characteristics to ensure the scalability to be determined.
There are a number of Web Services Test Automation tools available in the market today. Two worth mentioning are: WebInject, SoapUI & TestMaker. Before we briefly discuss each of these, let us turn towards some of the prime features of the Web Services Test Automation Framework:
WebInject is a free tool for automated testing of web applications and web services.
WebInject is primarily an execution and reporting engine. It can be used to test individual system components that have HTTP interfaces (JSP, ASP, CGI, PHP, AJAX, Servlets, HTML Forms, XML/SOAP Web Services and REST etc.)
It can also be used to create a suite of [HTTP level] automated functional, acceptance, and regression tests.
SoapUI is designed for validating web services. SoapUI is a tool for functional testing, web services testing, security testing and load testing.
It is the most used web services API testing tool.
SOAP is language written using XML, hence is platform independent.
Sometimes RPC (Remote procedure calls) are blocked by firewalls and proxy servers, to overcome such issues SOAP was designed.
The SOAP debugger acts as a Web services proxy that allows you to intercept and inspect the SOAP request and response messages that are sent between the client and server SoapUI has User Friendly GUI SoapUI enables developers, testers, and IT managers - both technical and nontechnical - to build test suites and test cases of SOAP-based and REST-based Web services in an easy graphical environment.
SoapUI Request, sends an HTTP request to a destination and accepts a response.
SoapUI will also unleash load tests on a Web service
TestMaker is a web service testing application from PushToTest.
HTTP Protocol level testing for optimization of Web pages.
To achieve business service monitoring in Service Oriented Architecture (SOA) and Web Service environments, Eviware SoapUI is the recognized open-source Web service test suite development tool.
PushToTest integrates SoapUI fully and takes SoapUI to entirely new levels of testing and service management. PushToTest TestMaker operates SoapUI tests
The largest of TestMaker's libraries is TOOL (Test Object Oriented Library), which includes classes for handling all sorts of communication protocols like HTTP, HTTPS, SOAP, POP3, JDBC etc. You can, therefore, create test cases that approach or surpass any client application the Web service is likely to be called by.
