Hey, I am considering to grab the task, however I feel like there is a lack of scenarios to cover. Do you have any idea what behavior we want to test?

What is the current code coverage of this? @Anipik Can you provide a coverage report?

Can you provide a coverage report?

@deeprobin, you can just do dotnet build /t:test /p:Coverage=true in the relevant test directory to create a report.
