Hi @laywang142 ,

Thank you so much for creating these! I ran the covr report and almost all of your new unit test files have 100% coverage. There are two checks that are below 100% because there is one scenario not covered in the unit testing. Could you please include those remaining scenarios? I've pasted the screen captures below.

Thanks a lot!
