- System modeling
  In this topic, you can find information about using the system model feature. You can also find the tasks that you can perform to create a system model. You must configure a repository to save the system model that you created for the application under test.
- Prerequisites to running tests
  Before you can run a test asset in a project on Rational® Test Automation Server, you must read the information about the different tests assets. You can add a remote static agent or Docker host to the project and then select it as an alternate location to run the test assets.
- Management of agents
  You can find information about managing performance agents that you install on remote computers and then configure the remote agents to register with IBM® Rational® Test Automation Server. After the agents are registered, you can add them to your projects and then select them as locations to run tests.
- Management of Docker hosts
  You can find information about the tasks that you can perform on remote Docker hosts. After you set up a remote Docker host, you can register the Docker host with IBM® Rational® Test Automation Server. You must then add the registered remote Docker host to your project before you can run tests on the remote Docker host location.
- Management of remote Kubernetes clusters
  You can find information about the tasks that you can perform on remote Kubernetes clusters. After you set up a remote Kubernetes cluster, you can register the external cluster with a team space on IBM® Rational® Test Automation Server. You must then add the remote cluster to a project before you run test assets or resources on the remote Kubernetes cluster.
  - Considerations for using a remote Kubernetes cluster
    When you want to use a remote Kubernetes cluster as a location to run the supported tests or test resources, you must read the considerations first.
  - Registering a remote Kubernetes cluster
    You must register a remote Kubernetes cluster to your team space on Rational® Test Automation Server before you add the remote cluster to your project.
  - Viewing remote Kubernetes clusters
    You can view the clusters that you have registered with a team space on IBM® Rational® Test Automation Server to view their details or edit their configurations.
  - Adding a remote Kubernetes cluster to a project
    You must add a remote Kubernetes cluster to your project after you register the cluster with your team space on IBM® Rational® Test Automation Server.
  - Editing configurations of a remote Kubernetes cluster
    You can edit the kubeconfig file, address, namespace, name, or ingress details of the remote Kubernetes cluster that you added to a team space on IBM® Rational® Test Automation Server.
  - Removing a remote Kubernetes cluster from a project
    You can remove a remote Kubernetes cluster from a project in a team space on IBM® Rational® Test Automation Server when you no longer need the cluster to run tests.
  - Unregistering a remote Kubernetes cluster from a team space
    You can unregister a remote Kubernetes cluster from a team space when you no longer require it.
- Test run configurations
  You can configure and run tests in IBM® Rational® Test Automation Server after you add the test resources to your project in your team space.
- Configuration of a scan of an application code
  You can use Rational® Test Automation Server to scan your application code for security vulnerabilities similar to using the HCL AppScan CodeSweep plugin to scan code in Visual Studio.
- Management of running tests
  Find information about the tasks that you can perform on a test that you configured for a run either while it runs or after it completes the run.
- Management of virtualized services
  You can find information about the tasks that you can perform on and manage the virtualized services that run on Rational® Test Automation Server. You can start or stop the virtual services that are connected to Rational Test Automation Server. You can view the routing rules and usage statistics of virtualized services, agents, or intercepts that are connected to Rational Test Automation Server.
- Test results
  After the tests, Suites, or schedules are run and completed, you can view the results and open the reports in IBM® Rational® Test Automation Server to analyze the verdict, the performance, and statistics. You can also re-execute tests and schedules from the Result page with the same commit id.
- Resource monitoring
  When you apply load to a system under test, the amount of resources consumed by your system is increasing. If the capacity of the resources does not match the load, you can see performance issues in the results. Resource monitoring in Rational® Test Automation Server helps you monitoring the resources of a system and establish the performance metrics and usage data of the system. Thus, you can observe the health of these resources while a schedule is running.
- Configuration of a change management system
  When you use any application to create and track defects (bugs), issues, or other work items, you can configure the application as a change management system on Rational® Test Automation Server. You can then create defects (bugs), issues, or other work items without the need to open your application.
- Integrations with other applications
  You can integrate certain applications with IBM® Rational® Test Automation Server to run tests, view the test results, and create defects.
- Managing access to the server
  Desktop clients and third-party integrations use offline user tokens to connect to Rational® Test Automation Server.
- Working with IBM® Rational® Test Automation Server REST services
  When you want to use the IBM® Rational® Test Automation Server REST APIs in your test automation scripts, you can view the REST APIs that are exposed by IBM Rational Test Automation Server. You can also run the APIs from within your project in IBM Rational Test Automation Server.

Unregistering a remote Kubernetes cluster from a team space

You can unregister a remote Kubernetes cluster from a team space when you no longer require it.

Before you begin

You must have completed the following tasks:

Registered a remote Kubernetes cluster with your team space on IBM® Rational® Test Automation Server. See Registering a remote Kubernetes cluster.
Ensured that you are assigned a role as a Member or Project Creator in the team space. See Managing members and their roles in a team space.
Ensured that you are assigned a role as a Project Owner or Tester in the project. See Managing access to server projects.

Procedure

Log in to Rational® Test Automation Server.

The team space that contains your project is displayed.
Click Infrastructure > Agents and Intercepts in the navigation pane of the team space.

The Agents and Intercepts page is displayed.

You can view the agents, intercepts, Dockers, or clusters that are registered with the team space on Rational® Test Automation Server.
You can view the clusters that you own in any of the following ways:
- Search for the cluster by entering the name of the cluster in the Search field.
  Note: You can enter either the full name or any text that is in the name. The search is enabled for case-sensitive text that you can enter.
- Sort the Type column to sort the items, and then identify the cluster by the name or owner.
- Sort the Agents column to sort the items, and then identify the cluster by the name or owner.
Identify the cluster that you want to remove.

Note: The and icons are displayed in the Actions column in the row of the cluster only if you own the remote cluster.
Unregister the cluster by completing the following steps:
1. Click the Unregister cluster icon .
2. Click Unregister in the Unregister cluster dialog box.
A message is displayed that the remote cluster is unregistered successfully.

Results

You have unregistered the remote cluster from a team space on Rational® Test Automation Server. You cannot run test assets or resources on this remote cluster if it is added to your project. You might have to add it again to your team space, if you want to use the remote cluster in your projects.
