Testing with HCL OneTest™ API

Starting from V9.1.1, you can use HCL OneTest™ API extension to execute API tests. In HCL OneTest™ Performance, you can either import the projects from HCL OneTest™ API or manage them from HCL OneTest™ Performance by establishing the connection between the products. In HCL OneTest™ Performance, you can create a schedule or compound test to run the IntegrationAPI tests by using the Agents.

Before you begin

To be able to work with API tests, you must install HCL OneTest™ Performance Extension for HCL OneTest™ API.

You also need a HCL OneTest™ Performance agent or a HCL OneTest™ API agent to execute the tests remotely. When installing HCL OneTest™ API agent, it is recommended to choose This Agent will only run probes option.

Moreover, if you update API tests in HCL OneTest™ Performance and want to apply the updates back to HCL OneTest™ API, you must install HCL OneTest™ API and define the path to its installation directory to set the connection.

Following are the use cases to work with API tests in the HCL OneTest™ Performance:

Both the products are installed and you connect to the API project, or you open the API resource directly from Test Navigator view and you work directly with the sources files.
HCL OneTest™ API is not installed and you import the projects in the HCL OneTest™ Performance workspace.
Note: The imported tests must be edited in HCL OneTest™ API. Similarly, the schedules and compounds tests must be edited in HCL OneTest™ Performance.
To execute Performance tests with imported tests, the HCL OneTest™ API agent must be installed along with the HCL OneTest™ Performance agent. The environment variable INTEGRATION_TESTER_AGENT_HOME must be defined on each location where the agent is installed, and must point to the root directory of the HCL OneTest™ API agent installation.
The following environment variables must be set to apply licenses:
```
HCL_LICENSING_ID = ServerID
```
```
HCL_LICENSING_URL = Server url
```

Connecting to an existing API 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 HCL OneTest™ API 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 HCL OneTest™ Performance, right-click on the Test Navigator, select New > Other > > Connect to an HCL OneTest™ API 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:
- Click Do nothing to only import the project.
- Click Open Create Rate Schedule wizard to select the test, create a Rate Schedule, and add the test to it.
- Click Open Create VU Schedule wizard to select the test, create a VU Schedule, and add the test to it.
- Click Open Create Compound Test Wizard to select the test, create a Compound test, and add the test to the Compound test. For more details, see Creating a compound test and Adding tests into a compound test.
  For example: select the Open Create VU Schedule wizard action and click Next.
  The Create Rate Schedule for Integration Tester or CreateVU Schedule for HCL OneTest API wizard displays the list of tests contained in your project.
- Select one or more tests and click Next.
- In Schedule File Name and Location wizard, select a schedule in an existing project, or create it from this window. You just need to enter a name for the new schedule and click Finish. The procedure is the same for the compound test.
- The Test Navigator displays the projects:
  - The HCL OneTest™ API project you are connected to, or that you imported, with the tests.
  - The HCL OneTest™ Performance project containing the schedule or compound test. If HCL OneTest™ API is installed, Connected is indicated near the name of the project in the Test Navigator. The Schedule or compound test automatically opens in the dedicated editor.

Setting HCL OneTest™ API preferences

To be able to open an HCL OneTest™ API project from HCL OneTest™ Performance 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 HCL OneTest™ Performance, click Window > Preferences > Test > HIT Integration.
Click Browse and set the installation path to HCL OneTest™ API execution file. On Windows, the default location would be C:\Program Files\HCL\IntegrationTester.exe.
Click Apply and OK.

Opening HCL OneTest™ API resources from the Test Navigator

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

Importing HCL OneTest™ API project

If both the products are not installed on the same machine, you can import an HCL OneTest™ API project in your workspace. Another reason for the import is when you have HCL OneTest™ API installed but you do not want to connect to the HCL OneTest™ API 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 HCL OneTest™ API 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 or schedule editor automatically opens.

Modifying HCL OneTest™ API environments in HCL OneTest™ Performance

In the schedule or compound test, you can select HCL OneTest™ API tests and change the environment of each test. The environments are set in HCL OneTest™ API, you can only change the selection from the edited schedule or compound test.

Open the schedule or compound editor and select a test.
In the HCL OneTest™ API 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 schedule or compound test and select Replace HCL OneTest™ API 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 schedule or 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 HCL OneTest™ Performance to run the Integration tests, see Creating a VU Schedule or Creating a compound test.

You can add a dataset mapper in the compound test or schedule for tests that are using multiple tags. See Adding Dataset Mapper to map tags in the HCL OneTest™ API tests with the variable values of HCL OneTest™ Performance.
