    - 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.
    - Task flow: Working with the IBM® Rational® Test Control Panel Environments dashboard
      You can use the Rational® Test Control Panel Environments dashboard to perform various tasks such as starting, stopping stubs and scenarios, and modifying stub configurations after you have published stubs to Rational Test Control Panel. You can also lock the environment that contain the published 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.
    - 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.
      - Publishing stubs
        You can publish a stub to IBM® Rational® Test Control Panel, Dockerfile and build context, Kubernetes, or Istio with Kubernetes by using the Rational Integration Tester Publish Stubs wizard.
      - Running stubs
        Several methods are available to start and stop the stubs. You can also modify and control stubs while they are running.
        Starting stubs
        IBM® Rational® Test Control Panel, Rational Integration Tester, Docker, or IBM Cloud Private can be used to start stubs.
        Starting stubs by using the Server method
        When you want to start stubs that are published to IBM® Rational® Test Control Panel, you can do so from the Environments Dashboard. Also, when you cannot use or access Rational Integration Tester to control stubs, you can use the Environments Dashboard of Rational Test Control Panel to start the stubs.
        Starting stubs by using the Integration Tester method
        Rational® Integration Tester can be used to start stubs, but IBM® Rational Test Control Panel provides more control over the startup of a stub or a set of stubs.
        Running stubs in a Docker container
        After you publish one or more stubs to a Dockerfile and build context and you built a Docker image from those files, you use the docker run command to run the image in a container.
        Running stubs in Istio or Kubernetes
        After you publish one or more stubs to Istio or Kubernetes, you must upload the project files to a file server and edit the YAML file to point to the URL of the file server before you can run the stubs.
        Scenarios
        In IBM® Rational® Test Control Panel, you can create scenarios, which are collections of configured stubs that can be started and stopped together.
        Stopping stubs
        You can use IBM® Rational® Test Control Panel, Rational Integration Tester, or Docker to stop the stubs.
      - Modifying running stubs
        If you are using Rational® Integration Tester to run a stub, you can modify the stub while it is running.
      - Controlling running stubs
        You can control stubs that are running in a number of ways.
      - Behaviors for stubs
        You can create a simple behavior called "echo" that will expose one function and one event for use by a IBM® Rational® Test Virtualization Server stub.
    - 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.

Running stubs in Istio or Kubernetes

After you publish one or more stubs to Istio or Kubernetes, you must upload the project files to a file server and edit the YAML file to point to the URL of the file server before you can run the stubs.

Uploading the tar.gz files

You must upload the tar.gz files for the project and library files, if available, to a file server. From the file server these files can be downloaded automatically when the YAML starts an intiContainer called fetch-project that is run before the stub container is started. The project and library files from this file server are fetched by the YAML file.

Editing the YAML file

You must edit the YAML file before you run the published stub. Complete the following steps to edit the YAML file:

Open the YAML file for editing on your computer.
Edit the curl command under the Deploying args: displayed as:
```
- curl http://artifcats/files/<identifier name>_project.tar.gz
```
where <identifier name> is the name of the project containing the stubs that you published to Kubernetes or Istio from Rational® Integration Tester, to input the URL of the file server and location of the files, as:
```
- curl http://<URL of the file server/location of the files>/<identifier
                _project.tar.gz
```
Optionally, input the URL of the file server, location, and name of the library files in the corresponding curl command.
Optionally, add the value for the Rational® Common Licensing server, if you did not enter it in Rational® Integration Tester when you published the stubs to Kubernetes or Istio.
```
env:
- name: RATIONAL_LICENSE_FILE
  value: '<IP of the License Server>'
```
Save and close the YAML file.

Running the stubs

Depending on the OS of the Kubernetes container where you are deploying the stub, you must run the appropriate command. For example, you must run the following command in a Linux container:

# kubectl apply -f <Directory path>/<identifier name>.yaml

The following are created in the Kubernetes cluster when you run the YAML file:

A deployment pod is created that uses the <identifer> name of the YAML file.
A service is created that uses the <identifer> name of the YAML file.
A virtual service is created for each HTTP host used by the stubs.
