User experience

This release includes the following enhancements to the user experience and user interface:

Area Enhancement
Flexible license consumption

LoadRunner Enterprise offers VUFDs (Virtual User Flex Days), a flexible usage-based license. This license enables running a specified number of Vusers an unlimited number of times within a 24-hour period. This license was previously known as VUDs (Virtual User Days).

For details, see Manage licenses.

Create project from existing project

When creating a project from an existing project, you can now include monitors, monitors over a firewall, and analysis templates as part of the copied resources.

For details, see Create a project from an existing project.

Admin roles and permissions

The following updates were made to admin user roles and permissions:

  • Added a new Project Admin role that only has permissions to assign users to the projects to which the Project Admin is assigned. For details, see Create or edit a user.

  • Updated the Roles and Permissions module to include an Admin Roles tab, which lists the predefined admin roles and their permissions. For admin user role details, see Manage admin users and roles.

  • Extended Tenant Admin privileges to include full permissions over the tenant's private load generators. The Tenant Admin no longer needs to go to the Project context to add a host; they can add it from the Hosts module. Restrictions over regular host machines remain. For details, see Admin user role permissions.

Export Audit data

You can now export Audit grid data to an Excel file.

For details, see Export audited entities to Excel.

Script upload

The following updates were made to scripts:

  • Ability to upload VuGen scripts to LoadRunner Enterprise in .USZ format.

  • Improved performance for displaying large script files in the script viewer.

For details, see Scripts.

Server / Database time sync A warning message is displayed if the Database Server and LoadRunner Enterprise Server clocks are not synchronized.
Locked entities

If an entity such as a test, script, monitor profile, or analysis template is locked, the user locking the entity is now indicated in the Entity Unlocker application.

For details, see Unlock entities and manage unlocking jobs.

VuGen, protocols, and LoadRunner Developer

Virtual User Generator (VuGen) includes the following enhancements:

Area Enhancement
LRE integration The integration with LoadRunner Enterprise now includes an option to perform SSO login in your default browser, instead of the embedded browser.
WinInet replay engine When using the WinInet replay engine to replay scripts, the HTTP request receive timeout in the runtime settings is now supported for timeouts greater than 30 seconds (in addition to timeouts of 0-30 seconds).

The VuGen and third-party protocols include the following enhancements:

Area Enhancement

The following updates are included for TruClient scripts:

  • Chromium browser support has been updated to version 108.

  • You can no longer record and develop TruClient Internet Explorer scripts. Existing TruClient IE scripts can still be run in Controller scenarios, but support will be removed in a future LoadRunner Enterprise version.

  • Various security updates.


The following updates are included for DevWeb scripts:

  • Expanded pacing options are available to run iterations for DevWeb scripts. You can now define delay or interval pacing, with fixed or random values.

  • When adding extractors to your script from the snapshot pane, VuGen assesses the origin file type for the selected text, and inserts the appropriate extractor in the script. For example, XML or JSON.

  • When using the failOn option with the text check extractor, if there is an error as a result of the extractor, DevWeb adds the error to the snapshot file. (Log level must be set to Error or higher.)


The following updates are included for Web - HTTP/HTML scripts:

  • Support for record and replay for the WebSocket permessage-deflate extension. The extension is included in the web_websocket_connect API if detected during recording.

  • Support added for the creation of a WebSocket connection when generating a script from a HAR file (with the web_websocket_send function added manually).

  • When recording with port mapping using an SSL connection, you can set a custom Server Name Indication (SNI) in the ClientHello message.

  • In the script runtime settings, you can now define specific HTTP codes to be treated as warnings instead of errors when the script is run.


The following updates are included for .NET+ scripts:

  • The installed .NET 6 SDK is now identified automatically using internal logic.

  • A Shared Libraries page has been added to the .NET+ Runtime Settings, enabling you to add paths for referenced DLLs that are not copied locally.

  • Code autocomplete is now supported in the VuGen Editor.

Citrix ICA

The following updates are included for Citrix protocol scripts:

  • You can now record scripts for the Citrix protocol on a Citrix cloud (DaaS) environment, using services installed on Microsoft Azure.

  • This release includes new APIs that move and resize a window based on the unique window ID: ctrx_window_resize_by_id and ctrx_window_move_by_id

  • A new WaitFor parameter is included in the ctrx_sync_on_text_ocr and ctrx_sync_on_bitmap APIs.

  • Support added for child windows in window-handling APIs.

RDP The RDP protocol now supports SSL and CredSSP security for recording scripts.

For details, see the VuGen What's New.

LoadRunner Developer includes the following enhancements:

Area Enhancement
gRPC bidirectional stream requests DevWeb scripts now include support for bidirectional streaming RPC requests. With this addition, DevWeb now provides full support for gRPC.
Extractors returning multiple values

When multiple values are returned by the DevWeb extractors, and the converters or transform options are defined, they now applied to all returned values.

This applies for the following extractors:

  • For JSON path or XPath extractors, returnMultipleValues is set to true.

  • For Boundary or Regexp extractors, occurrence is set to All.

Encryption key

You can pass an encryption key value directly on the command line, instead of providing the location of the key file.

Azure Key Vault

When working with Microsoft Azure Key Vault secrets, you now pass an object rather than arguments to the key vault.

For details, see the LoadRunner Developer What's New.
