3. UACTT Training - Client Introduction (1 of 3)
What is it? A specialized UA Server & Client (hybrid) designed to test a UA Client for compliance. Where is it? Who can get it? OPC Foundation Corporate Members What is tested? UA Servers and/or UA Clients Coverage? Most base/core services. Several UA profiles, more coming soon… Extensible? Yes, you can add your own tests. Easy to use? Yes, once you’ve learned the basics.

4. UACTT Training - Client Introduction (2 of 3)
How it works: Each Service is tested manually to see: a. if a service-call is made correctly b. if the client handles valid responses correctly c. if the client handles invalid responses correctly Test authors? Compliance Working Group Developers? Compliance Working Group Can I help? Absolutely! We always need help creating test-cases and test-scripts, and for testing. Contact

5. UACTT Training - Client Introduction (3 of 3)
How do I pass? Your product must pass all tests in all selected profiles and/or conformance units. Am I Certified? Passing the UACTT does not mean you are certified by the OPC Foundation. It means that your product is ready for certification in a Test Lab. CTT used in Lab? The Certification Test Labs use the same version. Use CTT When? The best time is during product development. All UA products must pass the UACTT prior to release. Additional Help: Complete help-documentation is provided with the UACTT. Test-case documentation is also provided.

There are (by default) 3 “widgets” at the bottom:
Results: a hierarchical audit-log of test activities and results.
Script Output: a verbose trace of test-script activity.
Trace: a generalized trace of UACTT activity.
See the complete details of each Service call request and response here
UA Service calls are listed here

The Client Trace widget contains a powerful Filter capability for selecting which UA calls to list in the trace.
Checked services are displayed; unchecked are hidden (but still logged).

12. UACTT Training - Client Finding Help (2 of 2)
All test-cases used by the Lab are exported into HTML pages that are available with the UACTT. Test-case documentation can be launched from the main documentation or from the Help widget.

13. UACTT Training - Client Test Tool Configuration (1 of 6)
Normally, a Client connects to a Server directly. When using the UACTT we must force the Client to connect to the CTT; the CTT will connect to the UA Server – as a proxy.

14. UACTT Training - Client Test Tool Configuration (2 of 6)
After launching the UACTT you must create a new Project. You must choose a Server or Client project type, and then specify the project name and save-location.
The newly created CTT project contains a copy of all test-scripts, script library, and a certificate store.

15. UACTT Training - Server Test Tool Configuration (3 of 6)
We must configure the CTT to connect to the UA Server and also to expose an endpoint for the UA Client…
Step 1. Enter the EndPoint URL for the UA Server you want to consume data from.
Note: The Advanced folder contains settings that can be ignored.
Step 2. Copy the “Endpoint URL” value and paste it into your Client.
Step 3. Click the OK button.

16. UACTT Training - Server Test Tool Configuration (4 of 6)
Here’s a real-world setup using the OPC Foundation DataAccess sample Server & Client… (a) DA Client to CTT (Endpoint URL); (b) CTT to DA Server (Underlying Server URL).

17. UACTT Training - Server Test Tool Configuration (5 of 6)
Your Client will probably call FindServer or GetEndpoints and then bypass the CTT. To avoid this we must modify FindServers/GetEndpoints so all EndpointUrls’ point to the CTT.
Step 2. Click Execute current script…
Step 3. In your UA Client: make your connection to the UA CTT endpoint…
Step 1. Open (double-click) Start-FindServers-Intercept.js from the Library
Step 4. The UA CTT will inject its own Endpoint into FindServers and GetEndpoints

You UA Client should now be connected to your UA Server via the UA CTT…

19. UACTT Training - Client Testing & Debugging (1 of x)
First, test a UA Client’s normal behavior, such as a Read operation and observe the behavior…
Step 1. Observe the natural “call” made by the UA Client.
Step 4. Invoke the Read operation in your UA Client and observe the behavior of your UA Client.
Here, the purple line indicates the UACTT has modified the original server response (to force an error).
Step 3. Click Execute current script…
Step 2. Double-click a script to be used for testing…

20. UACTT Training – Client Testing & Debugging (2 of x)
When ready to move onto the next UA Service call to test, you will probably need to clear the event handler to prevent further injections. Here’s how…
Step 2. Click Execute current script…
Step 1. Double-click DetachHandlers.js…
Step 3. Open your next script (for testing) in the next [applicable] conformance unit.

21. UACTT Training - Client Script Customization
You can add your own scripts to a conformance unit! Here’s how…

22. UACTT Training - Server Next Steps…
Once your UA Client passes all applicable tests:
Conduct Interoperability Testing
Conduct Behavior Testing
Conduct Resource-efficiency Testing
Request Certification in the Test Lab:
This information is available in the CTT Test-Cases help pages.
