Then add this to the very top of your
test/helper.rb (or similar)
duvet won't work for Ruby 1.8 you may want to rescue the error and
# ignore error
You can change the defaults by passing options to
Duvet.start, for example:
Duvet.start :dir => 'coverage', :filter => 'app/lib'
:dir is the directory to write the coverage to and
:filter is a string
that a files path must match against. A regular expression can be used for more
control, but most of the time a simple string will suffice.
You can see the output of running
duvet on itself here.
