Display Answer

Answer: A

Explanation: When performing integration testing, you should test the interactions of all the components in an application. Because the Web service exposes business logic, you need to ensure that the Windows Forms application calls Web methods of the Web service with expected input values and receives expected output values. Thus this testing strategy is correct. Incorrect answers: B. The team should not perform integration testing making use of calls from a test application. The point of integration testing is to use the real application to ensure that is interacts as expected with the Web service. C. The team should not make calls to dummy Web services. The whole point of integration testing is to ensure that the application interacts will all components correctly and a dummy Web service will yield dummy results. D. This would be inadequate since integration testing involves all components.
