LoadRunner Operator

This page introduces the LoadRunner operator, a workflow operator that allows piloting performance tests on a target system by leveraging Micro Focus LoadRunner. This page assumes you are familiar with the definition of a workflow and its tasks. If this is not the case, then check Creating automation workflows.

Prerequisites

This section provides the minimum requirements that you should meet to use this operator.

Supported versions

• Micro Focus LoadRunner 12.60 or 2020

• Microsoft Windows Server 2016 or 2019

  • Powershell version 5.1 or greater

User and WinRM configuration

To configure WinRM to allow Akamas to launch tests please read the Integrating LoadRunner Professional page.

All LoadRunner test files (VuGen scripts and folder, lrs files) and their parent folders, must be readable and writable by the user account used by Akamas.

Configuration options

When you define a task that uses the LoadRunner operator you should specify some configuration information to allow the operator to connect to the LoadRunner controller and execute a provided test scenario.

You can specify configuration information within the arguments that are part of a task in the YAML of the definition of a workflow.

You can avoid specifying each configuration information at the task level, by including a component property with the name of a component; in this way, the operator will take any configuration information from the properties of the referenced component

Required properties

• controller - a set of pieces of information useful for connecting to the LoadRunner controller

• scenarioFile - the path to the scenario file within the LoadRunner controller to execute the performance test

• resultFolder - the path to the performance tests results folder with the LoadRunner controller

Connect to a LoadRunner controller

To make it possible for the operator to connect to a LoadRunner controller to execute a performance test you can use the controller property within the workflow task definition:

controller:
  hostname: loarrunner.example.com
  username: Domain\LoadRunnerUser
  password: j(sBdH5fsG9.I56P%7n2XPjmgO6!ARm=

Operator arguments

This table reports the configuration reference for the arguments section.

Field	Type	Value restrictions	Required	Default	Description
controller	Object		Yes		The information required to connect to LoadRunner controller machine.
component	String		No		The name of the component from which the operator will take its configuration options
scenarioFile	String	Matches an existing file within the LoadRunner controller	Yes		The LoadRunner scenario file to execute the performance test.
resultFolder	String		Yes		The folder, on the controller, where Loadrunner will put the results of a performance test. You can use the placeholders {study}, {exp}, {trial} to generate a path that is unique for the running Akamas trial. It can be a local path on the controller or on a network share
loadrunnerResOverride	String	A valid name for a Windows folder	No	res	The folder name where LoadRunner save the analysis results. The default value can be changed in the LoadRunner controller.
timeout	String	The string must contain a numeric value followed by a suffix (s, m, h, d).	No	2h	The timeout for the Loadrunner scenario. If Loadrunner doesn’t finish the scenario within the specified amount of time, Akamas will consider the workflow as failed.
checkFrequency	String	The string must contain a numeric value followed by a suffix (s, m, h, d).	No	1m	The interval at which Akamas check’s the status of the Loadrunner scenario.
executable	String	A valid windows path	No	C:\Program Files (x86)\Micro Focus\LoadRunner\bin\Wlrun.exe	The LoadRunner executable path

Important notice: remember to escape your path with four backslashes (e.g. C:\\\\Users\\\\\...)

Controller arguments

This table reports the configuration reference for the controller section, which is an object with the following fields:

Field	Type	Value restrictions	Required	Default	Description
component	String		No		The name of the component from which the operator will take its configuration options.
scenarioFile	String	Matches an existing file within the LoadRunner controller	Yes		The LoadRunner scenario file to execute the performance test.
resultFolder	String		Yes		The folder, on the controller, where Loadrunner will put the results of a performance test. You can use the placeholders {study}, {exp}, {trial} to generate a path that is unique for the running Akamas trial. It can be a local path on the controller or on a network share.
loadrunnerResOverride	String	A valid name for a Windows folder	No	res	The folder name where LoadRunner save the analysis results. The default value can be changed in the LoadRunner controller.
timeout	String	The string must contain a numeric value followed by a suffix (s, m, h, d).	No	2h	The timeout for the Loadrunner scenario. If Loadrunner doesn’t finish the scenario within the specified amount of time, Akamas will consider the workflow as failed.
checkFrequency	String	The string must contain a numeric value followed by a suffix (s, m, h, d).	No	1m	The interval at which Akamas check’s the status of the Loadrunner scenario.
executable	String	A valid windows path	No	C:\Program Files (x86)\Micro Focus\LoadRunner\bin\Wlrun.exe	The LoadRunner executable path.

Important notice: remember to escape your path with four backslashes (e.g. C:\\\\Users\\\\\...)
