I remember using the tcm /import tool a couple of years ago, to automatically create a test case that is associated to the unit test in the specified dll. More details here: https://learn.microsoft.com/en-us/previous-versions/ff942471(v=vs.140)?redirectedfrom=MSDN
Basically, it would automatically create a test case and add the associated automation to it.
Do you know if there is something similar for AzureDevops?
Thanks!
