Tester Guide
This guide describes the tasks that you can perform for testing various domains, technologies, and applications. To enable testing, you must configure and enable the environment for testing.
Tester Guide - Service Virtualization
This guide describes the tasks that you can perform for using virtual services or stubs to simulate parts of an environment if the real services are not yet available or because they are difficult or expensive to use. This guide is intended for Integration Testers.
Creating message-based stubs
In Rational® Integration Tester, there are several methods that you can use to create a message-based stub.
Creating a stub by using MEP
You can use the message exchange pattern (MEP) properties for an operation, which define binding and timeout details, to create a stub.

  - Rational® Test Virtualization Server overview
    Rational® Test Virtualization Server is software that is used for creating, maintaining, publishing, and running message-based stubs and database stubs.
  - Virtualizing HTTP
    You can simulate an HTTP connection with a virtual service, also known as a stub.
  - Virtualizing HTTPS
    You can simulate an HTTPS connection with a virtual service, also known as a stub.
  - Virtualizing TCP
    You can simulate a TCP connection with a virtual service, also known as a stub.
  - Virtualizing a REST API without recording or synchronization
    You can virtualize REST APIs by using the Recording Studio, or by synchronizing WADL, Swagger, or RAML documents. When none of these options is available, you can still manually virtualize REST APIs that use path parameters.
  - Creating message-based stubs
    In Rational® Integration Tester, there are several methods that you can use to create a message-based stub.
    - Message-based stubs overview
      A message-based stub is essentially an Rational® Integration Tester resource that listens for incoming messages on a particular transport. A stub can reply to specific messages or message-types, matched according to incoming filters, by using message case actions.
    - Creating an empty stub
      You can create an empty stub. You can add content later by using the stub editor.
    - Creating a stub by using MEP
      You can use the message exchange pattern (MEP) properties for an operation, which define binding and timeout details, to create a stub.
    - Creating a stub populated with data
      You can create a stub based on the structure of the schema that is defined for the operation and the have the response payload populated with data.
    - Stubs with multiple operations
      You can create a single stub to manage multiple operations as a unit. Such a stub is required if you need to share state across several operations.
    - Stub creation by using the Recording Studio
      Use the Recording Studio to create a message-based stub if you have access to a live system from which you can record events.
  - Modifying message-based stubs
    You can use either the Test Editor or the Stub Editor to create, modify, and enhance any legacy or new stubs created by Rational® Integration Tester.
  - Creating and modifying database stubs
    You can create and modify database stubs in Rational® Integration Tester.
  - Configuring stubs to connect to Rational® Test Control Panel and the HTTP proxy
    A stub running on its own may not be sufficient in some cases, because it might have dependencies on services such as Rational® Test Control Panel or the HTTP proxy. If the stub is running on the public cloud and the services are running in the enterprise, you must configure the stub to connect to these services.
  - Publishing and running stubs
    You can publish stubs that are created in IBM® Rational® Integration Tester to IBM Rational Test Control Panel, Dockerfile and build context, Kubernetes, or Istio, if the stub is based on a supported transport.
  - Viewing results in Rational® Test Control Panel
    You can use IBM® Rational® Test Control Panel to display the results of tests that you run in both Rational Integration Tester and Rational Test Control Panel.
  - Viewing usage statistics of virtual services in Rational® Test Control Panel
    You can use IBM® Rational® Test Control Panel to display the usage statistics of virtual services across Rational Test Virtualization Server and IBM Rational Integration Tester.
  - Viewing reports in Rational® Test Automation Server
    All the project stakeholders can view test reports for multiple testing products from the Results page on IBM® Rational® Test Automation Server. You can access the Results page from a web browser. Therefore, there is no need to install the desktop client.
  - Troubleshooting: Rational® Test Virtualization Server
    You can use workarounds to common problems that you might encounter when you use IBM® Rational® Test Virtualization Server.

Creating a stub by using MEP

You can use the message exchange pattern (MEP) properties for an operation, which define binding and timeout details, to create a stub.

Before you begin

You must have created a transport and an operation. See Options for creating test resources.

About this task

To create a stub by using the MEP properties for a selected operation:

Procedure

Open the Rational® Integration Tester Test Factory perspective.
Expand the list of the Create New Stubs icon by clicking the arrow button on the toolbar.

Alternatively, right-click the operation where you want to create the stub, and then select New > Stubs > Stub using MEP.

Note: If at least one stub is already created, you can right-click the Stubs folder or one of the existing stubs, and then select New > Stub using MEP.

The Create new Stub dialog is displayed.
Enter a name for the stub in the Name field.
Click Options to open the Select message options dialog, and enter additional settings for messages.
Click OK.
The stub is opened for editing.

For information about using the Stub Editor to modify or enhance an MEP stub, see related links.
Make changes to the stub and then save it by clicking the Save icon on the toolbar.
Alternatively, you can save the changes to the stub by using any of the following methods:
- Clicking File > Save on the menu bar.
- Pressing the keyboard shortcut keys Ctrl+S.

Results

You have created a stub based on the MEP.

What to do next

You can run the stub. See Publishing and running stubs.
