Hello,
I am using the test tool (CTT) to test my OPC UA server.
I test the read and write functions from the nano server profile. I only use a few NodeId types (String, Uint32, Int32 and Float) and these are assigned with nodes in Server Test -> NodeIds -> Static -> All Profiles -> Scalar.
Only one of my String values is writable, all other values are read only. But when I mark the data types all says “Access: Read/Write” (in blue, down in the window).
I think this causes problems in the Write-tests. When I have these assignments I get errors in all of the tests, “BadNotWritable”. If I remove all assignments except the String-node I pass the tests.
Can I change the “Access: Read/Write” to “Access: Read” for my Int32, Uint32 and Float?
Thank you!

Hello,
unfortunately this is not possible. The CTT in its current version doesn't allow to identify the access rights on the configured nodes. Therefore I would recommend to execute the steps as you already described it.
1. Configure all available data types and do run all test cases which do NOT require a write call
2. Configure only the writable nodes and do run all test cases including all which DO require a write call
Another option would be to run it only once and check the reported errors of the CTT. The BadNotWritable should not be returned as a ServiceResult and neither for the node that is writeable (your string value). This way you only need to run the CTT with one configuration but need more time to take a look at the results.
For the certification testing this wouldn't be a problem as we would do exactly the same in the certification lab. We would create two different CTT configurations.
I hope this helps.
