In trying to get better coverage, I want to retire unused classes that have low coverage. When I try to deploy a commented out version of the class, I get an error:
Your organization's code coverage is 0%. You need at least 75% coverage to complete this deployment. Also, the following triggers have 0% code coverage. Each trigger must have at least 1% code coverage.
I don't see this as possible. If I try to deploy an updated class that still has a body, I get an org percentage that makes sense (73%, which I am trying to improve).
Does anyone understand why I can't retire these classes? Thanks
