问题
While using Devel::Cover in a test code which tests CodeA, does Devel::Cover have an option of switching the coverage off. Is there a way to switch the coverage module on or off as per user?
Test code tests CodeA. Devel::Cover commands are embedded in Test code whenever CodeA commands get tested.
Does Devel::Cover include any provision where this coverage collection can be switched on or off?
回答1:
There is a way to turn coverage on and off at runtime, but it seems that I have forgotten to document it. However, it is tested, so you can see how to use it there:
https://github.com/pjcj/Devel--Cover/blob/master/t/internal/criteria.t
This isn't exactly the same as if Devel::Cover had never been loaded, but rather it just stops Devel::Cover collecting coverage information for the criteria which are turned off.
