I'd like to increase my test coverage from 73% to 75% for Production. I am now increasing coverage on classes in Sandbox. I know how large are those classes without comments from
Apex Classes page.
I'd like to know what is the size of the total project to be able to calculate how much do I need to improve coverage of a set of classes to be able to deploy a change set.
Deploying a change set and then validating to see how much the coverage improved is much too time consuming.
