The QA professionals at SWAT Lab understand the complexities of testing Web Service applications and the challenges they present. With so many interconnected parts making up the application, testing is no longer just a matter of finding bugs that occur on a given user interface. Numerous factors must be considered when developing the test strategy, including:
The workflow is often made up of several components and layers that represent business logic, messaging, infrastructure and data and are separate from the user interface that the end user sees.
Different components can be on different machines, housed either within or far outside your network. Each component can also be delivered and maintained by distributed teams.
Web services are often an alphabet soup of different technologies. Each component can be a different technology and/or require different operating environments.
Each component can have its own product life cycle, so the runtime environment is almost always a "work in process" of legacy components being maintained alongside newly developed code.
Framework for Web Service Testing Success
The test strategy for a Web Service application must evolve with the architecture to genuinely test the business processes and maintain integrity across the entire workflow. Test Cases must be developed from use cases and event flows to validate the Web Service's functionality.
Once the Test Cases have been developed additional techniques can be employed to create a robust framework for testing the Web Services, including:
Standardized interfaces and messages for testing
Test automation: Record, replay and management of test scripts
Simulation: The ability to simulate applications as part of a regression test
Validation: Pass/fail verification at the component (messaging) and application (data store) levels.
