Run a performance test

This topic describes how to use LoadRunner Enterprise integration with Git plug-in to run a test using LoadRunner Enterprise. You can also configure the plug-in 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 plug-in to the Jenkins server

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

  1. Install the Jenkins server.

  2. Install the LoadRunner Enterprise integration with Git plug-in.

    For details on downloading and installing this plug-in, see 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:

  1. In the Build section, expand the Add build step drop-down and select Run Performance Test Using LoadRunner Enterprise (in step 6).

  2. 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 plug-in 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:

  1. In the Build section, expand the Add build step drop-down and select Run Performance Test Using LoadRunner Enterprise (in step 6).

  2. In the Run Test section (in step 11), select Create a new test, and in the Test To Create box, 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 folder in the test management tree of the LoadRunner Enterprise project.

Example: "MyMainFolder\\MySubfolder\\MySubSubFolder"

Note:

  • Do not include the LoadRunner Enterprise root folder (named "Subject").

Yes
test_content The content of the test that requires additional parameters specified in the test_content table below. Yes

lg_name

List of load generators to allocate to the group for running the script. The supported values are:

  • The hostname, as defined in LoadRunner Enterprise, of an existing load generator in LoadRunner Enterprise allocated as a host.

  • "LG" followed by a number, to use an automatically matched load generator (recommended).

  • "DOCKER" followed by a number, to use a dynamic load generator. This option requires that the lg_elastic_configuration parameter is defined (see the lg_elastic_configuration table below).

In the example above:

  • In the content:

    • Since no Controller and no load generator amount were specified, a random available Controller is allocated to the test just before it is run, and the lg_name parameter specified in each group is used.

    • In the group parameter:

      • Two scripts are added, each with a unique value in the group_name parameter, and the number of virtual users to run the group (vusers).

      • Since the ID of the scripts in the LoadRunner Enterprise project is unknown, the script_path parameter (without "Subject") followed by the script name is used, with double backslashes for separators.

      • The load generators used by each group are specified (in this case, load generators are automatically matched because the 'LG' prefix is used).

  • In the scheduler, all Vusers are initialized gradually (every 45 seconds), and the test will stop after 5 minutes (300 seconds).

In the example above:

  • Since the controller and the lg_amount parameters are specified, the specified Controller is used to run the test, and three automatch load generators are used and shared by all groups.

  • The content of the file is defined with seven groups, all being set with the rts parameter:

    • The pacing parameter is used with different options for all groups.

    • The java_vm parameter is used for five scripts with JavaVM for protocol.

    • The thinktime parameter is used with different options for four groups.

    • The jmeter parameter is used for two scripts with JMeter for protocol.

  • In the scheduler:, all Vusers are initialized gradually (every 120 seconds), and the test will stop after 10 minutes (600 seconds).
