Area Enhancement

The following updates are included for TruClient scripts:

  • Chromium browser support has been updated to version 108.

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.)

  • 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:

  • Code autocomplete is now supported in the VuGen Editor.

  • 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.

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.

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.
