Dear OPC UA Community,

I am currently using the CTT to test an OPC UA server, and I need assistance with testing Structure types (Custom types). I have been unable to locate any specific procedure or test cases related to testing these types within the CTT.

Could someone kindly provide a guidance on how to properly test Structure types or Custom types in the CTT? Additionally, if there are any specific configurations or considerations, I should be aware of when testing these types, that information would be greatly appreciated.

CTT Version Details:

Binaries:

Version: 1.11.0+411

UA Stack:

Version: 1.5.4 360IBA

Script Version Information:

Installed:

Client/Server:

Scripts built for Specification: 1.04.011

Script Version: 1.04.508

Current Project:

Scripts built for Specification: 1.04.011

Script Version: 1.04.508

Test Cases:

Client/Server Version: 1.03.009

Thank you in advance for your support!

Dear Manoj,

there are no special test cases or CUs yet integrated in the CTT but the structure nodes which are configured in the settings are being utilized during the Read and MonitoredItem tests. You'll find the configuration of the setting here:

Server Test --> NodeIds --> Static --> All Profiles --> Structures

If you have any additional tests you'd like to see or where you have experienced interoperability problems which are not yet covered by our testing, we are happy to receive your feedback and look for coverage of them as well.

Regards,
Alexander Allmendinger

Thank you for your clarification.

After adding the structure node ID in Server Test → NodeIds → Static → All Profiles → Structures, I ran the ReadAttribute test cases, but I encountered an error during the initialization step. As a result, I am unable to test the structure node for AttributeRead.

 

initialize.js 2025-05-19 17:01:16.497

Warning

2025-05-19 17:01:16.638

The following data type is not configured for testing: Scalar nodes not defined. Check settings: /Server Test/Nodelds/Static/All

Profiles/Scalar.

The CTT expects that prior to running the tests, all settings of the CTT are properly filled out. The initialize is checking the most important settings to be configured.

In your product, do you only have structures or also some other data points like Boolean, Floats, Int32, …? If so, please configure them as well so that the scripts find what they need to execute.

You’ll find all the settings and how they are properly configured described in the help of the CTT.
