Extra gems in gemspec?

[kitop]

The gemspec specifies

s.add_runtime_dependency(%q<webmock>, [">= 0"])
s.add_runtime_dependency(%q<coveralls>, [">= 0"])

Are those needed on runtime? or just development/test?

[graaff]

Both of these are only required in test/helper.rb so it seems to me that these should be development dependencies.
