Simulating services with stubs Service stubs enable you to simulate the behavior of an actual service for a wide variety testing or integration purposes. Service stub overviewService stubs are simulations of an actual service, which can be used to functionally replace the service in a test environment. A stub server replaces the actual application server.Creating a service stubYou can use a WSDL (Web Service Description Language) specification file to generate a service stub that can simulate the behavior of the original service and uses the exact same interface.Editing a service stubService stubs are generated with a single default response for each operation in the WSDL specification. You can edit the service stub to change the default responses or to add conditional responses that can simulate the actual service.Deploying service stubsYou deploy and run service stubs on a stub server, which is a small application server dedicated to running service stubs. The client application, or test, addresses the stub server instead of the actual application of the original service.Recording service stub activity in a log fileWith service stub logging, you can monitor the interactions between an application and the stub server. When the option is enabled, one log file is created for each deployed stub. The log files are presented as a formatted HTML report.Setting log level for service stubsWhile recording a service test, you can set the level of the log details that you want to collect for debugging purposes.Parent topic: Test Author Guide
