Hi!
I am trying to implement some unit test codes and run them, but the “Available Test Items” field is empty upon opening the Unit Test Page. When I try reloading available tests an error message pops up that tests could not be requested from http://127.0.0.1:80. Although the target is online, target status is in RUN mode, unit test solution is installed, B&R Web server is enabled and the requested port matches the configured one, still nothing can be seen on my window. I am not exactly sure how the testing works, where the test items are coming from and why I do not see them.. Can somebody help me find my test cases?

Hi,
it sounds like that everything is set up, but no test suite(s) / test cases are defined.
I would propose to check the unit test section of the B&R DevOps package on github, especially the Getting started pdf from here.
Additionally, I found a three steps video tutorial on YouTube which I personally haven’t seen before, but it looks very interesting:
Best regards!

Thank you for your prompt answer! I’ve watched the videos and went through the unit test section thoroughly and learned new things, however the initial issue hasn’t been solved. I created a new, blank project with only the sample tests in it and tried to execute those cases but the situation is the same. I can see the configured sample test items but that is just because there is a test configuration xml by default in the working directory. Once I delete the xml file, I cannot retrieve them. I also tried configuring Opc Ua, changed TCP port number and tried to reload available test items with the new configuration… unsuccessfully.
Hi,
so if I understand right, you use a blank project with imported TS_Unit_Test solution and the getting started sample from there.
Everything is setup, compiled, downloaded, but you see something like that:
If yes, please check again if the library “UtWs” is really deployed and downloaded (“UtWs” is the webservice backend for the unit test solution). If that library isn’t deployed, I get the behavior of the screenshot above.
After deploying and downlading “UtWs”, it looks like that:
I tested with a real target, so I’m not sure if the’re some more influences by ArSim / simulated PLC, but first I would propose to check if everything needed is deployed to get the simple sample running:
“Green” are the core components of the test framework (UnitTest, UtMgr, UtWs), “blue” are the test suite (task SPL_CalcTe) and the “object to test” (library SPLMyCalc).
Best regards.

I deployed the necessary libraries and the only difference from your window is that in the bottom-right corner I have “invalid service communication” instead of “no connection”
Hi,
I’m sorry, I tried but I’m not able to reproduce that issue.
I tried also to switch my existing configuration I tested on real hardware to Simulation, and it worked like expected.
The info “invalid service communication” I haven’t seen before. For me, it looks a bit like that the communication of the webservice based backend is somehow “disturbed/blocked” (maybe some security countermeasure issue?).
Could you please try to send a request to the backend directly by opening a browser when ArSim is running and using the URL “http://127.0.0.1:80/WsTest/”
What is the response you get?
At my running system, it looks like:
Hi,
Trying connecting to other ports gave me the “no communication” info, so the issue was really with the used port. I changed the webserver´s TCP port number, transferred it and then it works now.
Thank you for your help!

Hi @Martin_Szilagyi,
just because I’m curious about:
for my understanding, it worked after changing the tcp port 80 to a different port, because port 80 was already in use by some other system or webserver (because if port 80 isn’t in use by “someone else”, I don’t understand the status “invalid service communication” instead of “no connection”).
Can you confirm that, was/is port 80 in use by something different then ArSim?
Thanks in advance!
Hey!
Yes, it was used by something else and I wasn’t aware of that.

Hi.
If you’re here because your test items aren’t showing up even though your webserver setup is perfectly fine, check the StatusID of the UtMgrTestSuite() function block.
If you’re getting -1057750783 (utMgrERR_INVALID_PARAM), you can consult the AS-Help documentation, which will save you a ton of time by helpfully telling you to “check your call parameters.”
Of course, it won’t bother mentioning the one thing you actually need to know: you’re not allowed to use spaces or hyphens (-) in the Name string that you pass to the TestSuite function block. Why would they include that detail? That would be far too convenient.

I’m not sure which other characters are forbidden, but to be safe, you might want to avoid these as well: /*?"<>|&#$%§äöüÄÖÜ~'
