Hi, I am having trouble producing a coverage report.

Hello VladimirHorkym, did you get any solution for this problem?

[bfaganello]

Any update?
I'm having the same problem

[netbe]

me too

I think this is because your test coverage percentage is below the threshold. It's not a great fail message but I think that's all that causes it.
