Summary0008467: Base Info Server Capabilities 005.js might lead to send too large WriteRequet message
Description

UACTT version: v1.04.11-01.00.500

UACTT attempts to write the maximum array size declared by the server (in my case 10000) in the available array variable nodes.
Those write operations are done in a single OPC UA message, which is likely to reach the maximum OpcUa message size since we are testing array length limit.
As a general remark, UACTT should check for too large messages compared to the HEL-ACK declared sizes and split those messages into several messages when needed.
For the particular case of Base Info Server Capabilities 005.js writing the array variable nodes into separate WriteRequests might reduce the probability of reaching the message maximum size allowed. I attached a patch for this minor modification.

Changed to issue individual write request for every array test.

Also during the test I noticed that the test is silently skipped if no dynamic arrays are configured. I changed the script to also run if the max array size of the configured node matches the MaxArraySize.
Also added printing a skipped messages, when none of the nodes match the criteria.
