I just know from http://cheat.errtheblog.com/s/rcov how to do spec’ing
that excludes ruby libraries we have under vendor directory. So that I
can use it happily ever after.
rake spec:rcov SHOW_ONLY=“app”
I can explore rake tasks by typing
rake -T under ruby project
directory, but for this rake spec:rcov option, how would I know other
options that are available besides SHOW_ONLY ?
