I am just very confused by this conflicting thing. I do want to put webrat.log into my .gitignore so that I don't need to merge it every time. Yet I notice from Michael Hartl's Rails 3 tutorial book that webrat is a testing utility gem. So I really don't know whether I can ignore it.
Please help me, a newbie rails programmer.
For the most part, you should ignore every *.log file. They'll be deleted, modified, whatever every single time you run anything, and unless you really need them to be under control, they shouldn't be.
(And you basically never need them under source control.)
