A codebase was delivered to me for deploy and maintenance. It happens to be a very messy codebase that grow without code cleaning. So, I suspect that there is about of 80% of dead code there. By dead code here I mean legacy code that is not in use anymore, but is there sitting on the codebase. This number is more a felling than a measurement, the application is simple, there is about 3ain tables and a single flow, I've been tweaking for some months ... Also we have low low low traffic, so no millions of requests per second ...
I want to use something like code coverage to get a heat map of the code, so I can eliminate code that is for sure not in use, did anyone tried something like that? What are the options?
