rails--rails/activesupport/test/inflector_test.rb
Xavier Noria 31ceb5e67b decouples the implementation of the inflector from its test suite
Trying alternative implementations of the inflections
is hard because the suite is coupled with the current
one, setting ivars by hand etc. This commit relies on
initialize_dup, as long as you maintain that one you
can tweak the implementation.
