Licenses

This topic describes the different license types and bundles that you can purchase in order to run tests.

Purchase a license

A OpenText Core Performance Engineering license consists of both a run type and Vuser type. You choose a protocol bundle which includes the required Vuser types.

You can purchase a combination of run types and bundles to meet your team's needs.

The following run types are available for purchase:

License Description

Vusers (VU)

  • A fixed license enabling you to run any Vuser type.
  • Purchasable through your Customer Sales representative.

Vuser hours (VUH)

  • Enables you to run any Vuser type by the hour. 1 VUH is effectively 1 Vuser executing a load test for 1 hour. For details, see Virtual user hour (VUH) licenses below.

  • VUH licenses can be purchased through your Customer Sales representative or from the AWS Marketplace site, as a pay-per-use license.

To purchase more licenses, click the Settings button Settings button on the banner and select License information. Click Purchase more licenses.

Protocol bundles

The following table describes the available bundles and their associated protocols.

For details about the supported protocol versions, see the Support Matrix.

Protocol bundle Supported protocols Description
GUI

  • Selenium

  • TruClient - Mobile Web

  • TruClient - Native Mobile

  • TruClient - Web

  • TruClient 2.0 - Web (tech preview)

  • Web Vuser and Dev Vuser script types

  • Silk Performer script: Web browser-driven (AJAX)

A GUI Vuser emulates actions on the GUI level. For example, a user clicking a button. Because the GUI has to be rendered for each virtual user, these Vusers consume significantly more processing resources.

Note:

  • The Silk Web browser-driven protocol is shown in LRC as SP Browser-driven.
  • Before running a Silk Web browser-driven script on a specific browser, such as Chrome or Firefox, on an on-premises load generator, make sure that the browser is installed on the load generator machine.

  • Silk Performer scripts are only supported for on-premises load generators. For additional limitations, see Script limitations.
Web

  • DevWeb

  • Java Record Replay

  • Java Vuser

  • Java over HTTP

  • Kafka

  • Mobile Application - HTTP/HTML

  • MQTT (Internet of Things)

  • TruAPI

  • Web HTTP/HTML

  • Web Services

  • Silk Performer scripts: Web low level, Web business transaction, HTTP Live Streaming, and XML/SOAP

  • Dev Vuser script types

A Web Vuser emulates a user's actions at the network API level. For example, HTTP requests and responses without rendering the UI.

Supported Silk Performer protocols are: Web low level, Web business transaction, HTTP Live Streaming, and XML/SOAP. For details, see Support Matrix.

Note: Silk Performer scripts are only supported for on-premises load generators.

 
ERP

  • Oracle NCA

  • Oracle - Web

  • SAP GUI

  • SAP - Web

  • Siebel Web

ERP Vusers are used to test Enterprise Resource Planning systems, packaged suites of business applications.

SAP GUI is only supported for on-premises load generators.

Siebel Web is only supported for cloud load generators and Windows on-premises load generators.
Legacy

  • Citrix ICA

  • .NET

  • ODBC

  • RDP (Remote Desktop Protocol)

  • RTE (Remote Terminal Emulator)

  • Windows Sockets

A Legacy Vuser is used for running legacy LRP/LRE protocol scripts.

Note:

  • Legacy protocols are only supported for on-premises load generators.
  • ODBC, RDP, and RTE are only supported for Windows on-premises load generators.
Dev

  • Apache JMeter

  • Gatling

 A Dev Vuser is used for running third-party protocols, such as JMeter and Gatling.
All protocols All above protocols An All protocols Vuser can be used to run any of the above Vuser types.

Note: Beginning with version 2021.04, Flex and LeanFT scripts are no longer supported.

Virtual user hour (VUH) licenses

VUH licenses enable you to run Vusers by the hour. 1 VUH is effectively 1 Vuser running a load test for 1 hour.

Calculate the required number of VUH

As you create your test definition, the cart displays the number of VUH required to run your test.

Number of VUH required

The number of VUH is calculated by the following formula, rounding up to the nearest whole VUH:

(Vusers * Test execution time in seconds)/3600)

Note: Test execution time includes the test duration, the duration of all the ramp ups, the duration of all the tear downs, the paused time, and the actual delayed start.

Examples:

Vusers Ramp up Duration Tear down  Vusers * Total test time  Total VUH
1 00:05:00 00:40:00 00:05:00 1 * 50 minutes 1
10 00:10:00 00:40:00 00:10:00 10 * 60 minutes 10
10 00:10:00 00:10:00 00:10:00 10 * 30 minutes 5

Test runs with multiple scripts

When running a test with multiple scripts, use the above formula (where VUH is calculated for each script individually), and aggregate the cost of each script to get the total cost of the test run. This provides the VUH calculation at the test level.

Example:

Script name Vusers Ramp up Duration Tear down  Vusers * Total test time  Total VUH

Script

Test
My_Script1 1 00:05:00 00:40:00 00:05:00 1 * 50 minutes 1 16
My_Script2 10 00:10:00 00:40:00 00:10:00 10 * 60 minutes 10
My_Script3 10 00:10:00 00:10:00 00:10:00 10 * 30 minutes 5

30-day trial license

The OpenText Core Performance Engineering 30-day trial license provides Vuser hours, which enable you to run load tests on Amazon Web Services (AWS).

The trial license includes 1,000 GUI VUHs with the following restrictions:

  • 1 concurrent test limited to a 1-hour duration

  • Maximum concurrent Vusers per test run: 100 Web, 30 GUI, and 100 Dev

  • Maximum number of test runs: 10

  • Max hits/sec: 50

  • Pacing: 1 second (default). You can manually configure the pacing, but you cannot set it to less than 1 second.

For details on extending a trial license, contact your account manager or sales representative.
