Integration with Rational® Integration Tester

You can use Rational® Integration Tester extension to run integration tests from Rational® Performance Tester. You can either import the projects from Rational® Integration Tester or manage them from Rational® Performance Tester by establishing the connection between the products. You can also create a compound test to run the tests by using the Agents.

Before you begin

You must have completed the following tasks:

Installed Rational® Integration Tester Extension for Rational® Integration Tester.
Installed Rational® Performance Tester Agent and Rational® Integration Tester Agent to run tests remotely. When you install Rational® Integration Tester Agent, you must have selected the This Agent will only run probes option.
Defined the environment variable INTEGRATION_TESTER_AGENT_HOME on each location where the Agent is installed, and have pointed to the root installation directory of Rational® Integration Tester Agent.

Note: The environment variables INTEGRATION_TESTER_HOME and INTEGRATION_TESTER_AGENT_HOME are automatically created when you install Rational® Integration Tester 10.2.2 or later.

Setting environment variable

You must set the environment variable INTEGRATION_TESTER_AGENT_HOME and point it to the Rational® Integration Tester Agent installation directory if you are using Rational® Integration Tester 10.2.1 or earlier.

Run the following command to set the environment variable on Windows:
```
INTEGRATION_TESTER_AGENT_HOME = C:\Program Files\IBM\Agent
```

Run the following commands to set the environment variable on Linux:

INTEGRATION_TESTER_AGENT_HOME=/opt/IBM/RIT-Agent
export INTEGRATION_TESTER_AGENT_HOME
echo $INTEGRATION_TESTER_AGENT_HOME

If the environment variable is not set, the compound or schedule test run fails with an error message as depicted in the following image:

Connecting to an existing Integration project

When you connect both the products any change or delete action made in one product workspace is reflected on the other product workspace, if both the products are installed on your machine.

Warning: If you delete a project from the Test Navigator, be sure that the option Delete project contents on disk is not selected in the Delete Resources dialog, otherwise the project would be deleted in Rational® Integration Tester if it is connected. If the option is selected, the project is deleted in both the products.

If the option is selected, the project is deleted in both the products.

In Rational® Performance Tester, right-click on the Test Navigator, select New > Other > Rational Integration Tester > Connect to an > Rational Integration Tester > Project and click Next.
In the wizard page, click Browse and select the root folder that contains the project.
If the path contains a project, its name should automatically appear in Project Name and the Finish button should be enabled.
In When project is connected, you have to perform one of the following actions:

Setting Rational® Integration Tester preferences

To be able to open an Rational® Integration Tester project from Rational® Performance Tester Test Navigator, you need to have both the products installed on the same computer, and you must set the path to the execution file in the Preferences.

In Rational® Performance Tester, click Window > Preferences > Test > RIT Integration.
Click Browse and set the installation path to Rational® Integration Tester execution file. On Windows, the default location would be C:\Program Files\IBM\IntegrationTester.exe.
Click Apply and OK.

Opening Rational® Integration Tester resources from the Test Navigator

Once the preferences are set, you can open an Rational® Integration Tester project.
In the Test Navigator, open the project root node and children nodes, and at any level, right-click and select Open in Rational Integration Tester Workbench.
If Rational® Integration Tester is automatically detected, the workspace opens for the selected resources.
If Rational® Integration Tester is not detected, a dialog opens on a Preference page where you need to verify the path to the execution file.
Warning: Rational® Integration Tester cannot open more than one project at a time. If you have another project open, you will get an error. In that case, close Rational® Integration Tester and try to open the project again.

Importing Rational® Integration Tester project

If both the products are not installed on the same machine, you can import an Rational® Integration Tester project in your workspace. Another reason for the import is when you have Rational® Integration Tester installed but you do not want to connect to the Rational® Integration Tester project. In that case, the project is duplicated, any updates in one product workspace will not be reflected in the other product's workspace.

To import an Rational® Integration Tester project:
Right-click on the Test Navigator, choose Import and select Existing project into workspace.
Choose Select root directory or Select archive file; select a project to import and click Finish.
The selected project appears in the Test Navigator and the compound test editor automatically opens.

Modifying Rational® Integration Tester environments in

In the compound test, you can select Rational® Integration Tester tests and change the environment of each test. The environments are set in Rational® Integration Tester, you can only change the selection from the edited compound test.

Open the compound editor and select a test.
In the Rational® Integration Tester details, you can browse and change the properties of the selected test. The Test path, the Environments and Decription are automatically updated accordingly.
To select another environment for the Integration Tester test, use the dropdown menu.

Alternatively, you can change the environment selection for a test for a collection of tests:

Right-click on the tree at any level under a node in the compound test and select Replace Rational Integration Tester Environments.
In the Set Invocation Tester Environments wizard, the first page displays the list of projects that use the selected environment and the number of tests from project that use this environment in the compound test.
Select another used environment in the dropdown list. Click Finish. The new choice applies to the selected node and its children.

Next step is to create a compound test or schedule in Rational® Performance Tester to run the Integration tests.

You can add a dataset mapper in the compound test or schedule for tests that are using multiple tags. to map tags in the Rational® Integration Tester tests with the variable values of Rational® Performance Tester.
