This guide describes how to create test scripts in Rational® Performance Tester and enhances tests by applying different test elements such as dataset, variables, and verification points. This guide is intended for testers.
Simulating services with stubs
Service stubs enable you to simulate the behavior of an actual service for a wide variety testing or integration purposes.
Creating a service stub
You 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.

  - Creating tests
    To create a test, you record representative interactions with an application.
  - Editing tests
    After you record a test, you can edit it to include datasets (to provide variable data rather than the data that you recorded), verification points (to confirm that the test runs as expected), and data correlation (to ensure that returned data is appropriate for the corresponding request). You can also add protocol-specific elements to a test. When you edit a test, the modified items appear in italic type. The italic type changes to regular type after you save the test.
  - Compound tests
    You can create compound tests to help you organize smaller tests into scenarios that can then be run end-to-end. You can combine tests from different extensions to achieve end-to-end flow.
  - 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 overview
      Service 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 stub
      You 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 stub
      Service 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 stubs
      You 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 file
      With 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 stubs
      While recording a service test, you can set the level of the log details that you want to collect for debugging purposes.
  - Sending service requests with the generic service client
    The generic service client enables you to send requests to services for which you do not have a convenient client and to view the responses returned by the service.
  - Emulating workloads
    You emulate a workload by creating a schedule and adding user groups/rate runner groups, tests, and other elements to it.
- Test Execution Specialist Guide
  This guide describes tasks that you can perform on schedules, test execution with custom code, and Extending Rational® Performance Tester to support other protocols. This guide is intended for testers or test execution specialists.

Creating a service stub

You 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.

Before you begin

Service stubs are stored in test projects. If your workspace does not contain a test project, the test creation wizard creates one, enabling you to change its name. To store a service stub in a specific project, verify that the project exists before you create the stub.

If you are using Secure Sockets Layer (SSL) authentication, ensure that you have any required key files in your workspace.

The wizard can import WSDL files from the workspace, the file system, a remote repository, or from a URL. Ensure that the WSDL files use the correct syntax for the test environment. Service stub generation might not work with some Web Services Description Language (WSDL) files.

Procedure

In the workbench, click File > New > Other > Test > Test Assets > Service Test or click the New Service Stub toolbar button.
Select the WSDL of the service that you want to simulate. If necessary, you can import the WSDL from the file system, a URL, or a WSRR or UDDI repository.
Click Next.
Select a project location and a name for the new service stub. Click Finish.

Results

The wizard generates a working service stub that reproduces the interface of the original service as defined in the WSDL specification. Each operation is reproduced with a default response. You can edit the service stub with the stub editor to change the default response or to create conditional responses.
