Core Performance Engineering Aviator service

Core Performance Engineering Aviator is a cloud-based enterprise service that delivers Artificial Intelligence (AI) capabilities, to extend functionality within OpenText Performance Engineering products that are connected to the paid Aviator service.

Aviator provides scripting support for performance engineering products through VuGen, and automated, AI‑assisted analysis through Core Performance Engineering Analysis. For details on supported client instances and integrating with Aviator, see OpenText Core Performance Engineering Aviator in the OpenText Core Performance Engineering Help Center.

AI-driven scripting assistance

Aviator for Scripting in VuGen is generally available for all users. It provides assistance throughout the scripting process, helping to save time and simplify script creation.

Aviator for Scripting includes the following key capabilities:

• Selecting protocols: Provides assistance on selecting the most appropriate protocol for creating a script.

• Providing coding support: Assists with how to perform specific tasks in VuGen.

• Analyze errors: Helps identify and resolve script errors.

• Optimization: Reviews scripts and provides suggestions for improvement.

• Summarize: When a script is complete, Aviator can create a summary of key actions executed by the script.

When used together, these features save time and reduce the skill sets required for scripting.

For details, see Aviator for Scripting in the VuGen Help Center.

AI-driven data analysis

Aviator for Analysis in OpenText Core Performance Engineering Analysis is generally available for all users. It includes the following key capabilities:

• Conversational analysis: Performance engineers can interact with Aviator using natural language, directly within the dashboard environment.

• Error analysis: Performance engineers can interact with the Aviator directly in the Error grid to request general error details, possible root causes, and recommended remediation steps.

• Widget generation: Performance engineers can generate dashboard widgets using natural language or predefined prompts.

For details, see Aviator for Analysis in the OpenText Core Performance Engineering Analysis Help Center.

MCP support

MCP support is now available, providing a standardized and secure way to leverage AI-driven natural-language prompts to streamline and automate performance engineering workflows.

Using Copilot in Microsoft Visual Studio Code, natural language can be used to interact with the DevWeb MCP server to perform common tasks such as:

• Record a DevWeb script.

• Generate a DevWeb script from a HAR file.

• Generate a DevWeb script from a Swagger file.

• Run DevWeb scripts in Single mode, Single mode with iterations, or Load mode.

For details, see MCP integration in the OpenText Performance Engineering for Developers Help Center.

The Controller Service uses a new, modernized version of Controller, with its own engine. It provides a CLI to control and monitor load tests, including managing load generators, Vusers, and test runs. You can use your existing scenario .lrs files for the tests; or create YAML (.yml) files, enabling fast and convenient performance engineering activities. You can monitor test progress online, and view results in Analysis.

For details, see Run the Controller Service from the CLI. (Private Beta release)

The Virtual Table Server includes the following updates:

• Modernized VTS UI.

• Updated technology for running actions from the command line.

• Support added for Mozilla Firefox browser (Beta feature).

• New image-based object identification method.

• Support added for objects with dynamic randomly-generated IDs.

• Removal of the recorder extension, to meet security requirements regarding unpacked extensions.

• TruClient Browser run mode upgraded to multi-process.

• Support for Chromium browser version 143.

• Support for TruClient Browser equivalent to Mozilla Firefox version 146.

Support for Omnissa Horizon 8 is upgraded to versions 2406 and 2506.

The .NET+ protocol now supports the .NET 10 SDK.

• Improved chunk and stream handling when recording a web script using proxy.

• Support for newer versions of Wireshark when generating scripts using PCAP-Analyzer.

• Enhanced logging for web proxy recording.

• Updated headers list for web protocols (Fetch Metadata Request Headers, HTTP Client Hints Headers).

Support for JRE/JDK version 25.

The add-in protocols now support the latest Java IDE versions.

When running ScalUP for DevWeb tests on OpenText Enterprise Performance Engineering, you can now specify a location for automatch hosts. You can also run a command to obtain a list of available host locations.

You can run DevWeb scripts using data in a CSV file, rather than manually coding your test (Beta feature).

You can now use the Passed Transaction Rank Percentile rule in your SLAs. This rule validates if transaction duration measurements meet a percentile rank, for passed transactions only.

Documentation added for using node modules to incorporate third-party APIs in DevWeb scripts.
