Integrate with ALM using VAPI-XP

Supported in versions: LoadRunner Enterprise 202x; ALM 15.0 or later

This section describes how to integrate ALM with LoadRunner Enterprise using VAPI-XP. This enables you to run LoadRunner Enterprise performance tests, save test results, and view reports directly from ALM.

ALM integration flow

The following diagram illustrates the integration between LoadRunner Enterprise and ALM:

Prerequisites

Before you begin, you must perform the following on the ALM client machine:

Download and install the TFS plug-in for LoadRunner Enterprise on the machine hosting the ALM client.

The plug-in is available from: https://github.com/MicroFocus/Performance-Center-TFS-Plugin/blob/master/Extension/PC.Plugins.Installer.msi.

Create a PowerShell script file.

Go to the plug-in installation folder (the default path is C:\Program Files (x86)\OpenText\LoadRunner Enterprise Plugin), and create a PowerShell script file named AlmLreIntegration.ps1.

Copy and paste the following text into the AlmLreIntegration.ps1 file, and enter the LoadRunner Enterprise server URL, username, and password.

Copy code

Configure ALM as described in Configure ALM and run a performance test below.

Configure ALM and run a performance test

This task describes how to configure and run a LoadRunner Enterprise performance test from ALM using VAPI-XP.

Prepare the ALM client as described in Prerequisites.
Log on to ALM and select a domain and project.
Go to the Test Plan module (under Testing, select Test Plan).
Create a new VAPI-XP test based on the VAPI-XP test example below. For more about VAPI-XP test types, see VAPI-XP Tests in the ALM Help Center.
Define the parameters according to your choice.
Go to the Test Lab module (under Testing, select Test Lab).
Create a new test set and add a VAPI-XP test into it. At runtime, you can provide different parameter values for each test instance that you add.
Run the test set. After the test has finished running, check the status of test instance has passed in the Test Runs module (under Testing, select Test Runs).

You can view details of the test run in the run log (in Attachments).
View test runs in the reports.
1. A report for each test instance is uploaded to the relevant run. To see the report of a test set run, select the run, click the Attachments button, and extract the contents from the Reports.zip file.
2. Open the Reports.html file to display the Analysis Summary Report.
  
  Run status is updated based on the SLA status.

VAPI-XP test example

In this example, the following inputs are defined as parameters at the test level and can be changed during runtime.

Domain. The name of the LoadRunner Enterprise domain.
Project. The name of the LoadRunner Enterprise project.
TestID. The ID of the LoadRunner Enterprise test to be run.

For more about working with parameters, see Test Parameters in the ALM Help Center.
