Run a performance test using LoadRunner Enterprise

This topic describes how to use LoadRunner Enterprise integration with Git plugin to run a test using LoadRunner Enterprise. You can also configure the plugin to fully automate all aspects of the testing process: create a test from a YAML file or YAML content, synchronize tests from YAML files saved in a GitHub repository to a LoadRunner Enterprise project, and then run the test in LoadRunner Enterprise.

Upload the integration plugin to the Jenkins server

The LoadRunner Enterprise-Git integration plugin enables you to synchronize performance test scripts from a Github repository to a project on the LoadRunner Enterprise server.

Install the Jenkins server.
Install the Micro Focus LoadRunner Enterprise integration with Git plugin.

For details on downloading and installing this plugin, see Micro Focus LoadRunner Enterprise Integration With Git.
1. Go to Jenkins home > Manage Jenkins > Manage Plugins > Advanced.
2. In the Upload Plugin section, select the micro-focus-performance-center-integration.hpi file and click Upload.
3. Restart Jenkins if required.

Set up a Jenkins job to run tests using LoadRunner Enterprise

Set up a Jenkins job to run a performance test using LoadRunner Enterprise as described in Set up a Jenkins job to run tests in LoadRunner Enterprise, with the following changes:

In the Build section, expand the Add build step drop-down and select Run Performance Test Using LoadRunner Enterprise (in step 6).
In the Run Test section (in step 11), select Run an existing test, and enter the Test ID. You can get the ID from LoadRunner Enterprise > Test Management > Test Lab > Performance Test Set view. If the column is not visible, you can select it by clicking the Select Columns button.

Create a LoadRunner Enterprise test from YAML input

Available in plugin versions: 1.1.0 and later

When setting up a Jenkins job to run a performance test using LoadRunner Enterprise, you can create a new LoadRunner Enterprise test from YAML files stored in Git.

Set up a Jenkins job to run a performance test using LoadRunner Enterprise as described in Set up a Jenkins job to run tests in LoadRunner Enterprise, with the following changes:

In the Build section, expand the Add build step drop-down and select Run Performance Test Using LoadRunner Enterprise (in step 6).
In the Run Test section (in step 11), select Create a new test, and in the Test To Create field, enter text in YAML syntax representing a LoadRunner Enterprise test, or provide a path to a YAML file relative to the workspace.

The content of the field must either be:
- Text in YAML syntax composed according to the parameters described in the tables below. You must set values to the test_name and test_folder_path parameters, and continue with the test_content parameter and its sub-parameters.
- You can also specify as a value a relative path to a YAML file within the workspace (or within your Git repository cloned within the workspace). In the YAML file, only specify the parameters defined in the test_content table. The following logic is used to create the LoadRunner Enterprise test:
  - The file name (without extension) is used as the test name.
  - The location of the file in the Git repository is the location of the test under the root folder ('Subject') in the Test Management tree.
  - The content of the YAML file must consist of the parameters, and their sub-parameters, listed in the test_content table below.

Note:

All parameters must be in lowercase.
When a backslash (\) occurs in a value provided to a parameter (for example, a folder separator in a file path), a double backslash (\\) must be used instead.

Root parameters of the field:

Parameter	Description	Required
test_name	The test name.	Yes
test_folder_path	The location of the test in the Test Management folder tree of the LoadRunner Enterprise project. Example: "MyMainFolder\\MySubfolder\\MySubSubFolder" Note: Use a double backslash (\\) to separate folders. Do not include the LoadRunner Enterprise root folder (named "Subject").	Yes
