, I absolutely understand where you are coming from on 100% test coverage. It may be fairer to say I am experimenting with it. I have all sorts of thoughts on the subject. For a start with a new module it is straightforward, to keep the test coverage up to 100%. For an older module you can only hope to approach it aggressively. It is interesting to take a module that you regard as critical, and run Devel::Cover on it - and to compare the results with the bug list - and to ask how many of those bugs could have been avoided with better testing. When I have done that and tried to discuss the results, the responses such as they were struck me as complacent. Also I am working on restructuring and improving CGI::Application::Plugin::Authentication
. As a I did not write that module originally, getting the test coverage up seems a constructive way of knowing and controlling the impact of my changes.
