module RR
# RR::DoNotAllowCreator uses RR::DoNotAllowCreator#method_missing to create
# a Scenario that expects never to be called.
#
# The following example mocks method_name with arg1 and arg2
# returning return_value.
#
# do_not_allow(subject).method_name(arg1, arg2) { return_value }
#
# The DoNotAllowCreator also supports a block sytnax.
#
# do_not_allow(subject) do |m|
# m.method1 # Do not allow method1 with any arguments
# m.method2(arg1, arg2) # Do not allow method2 with arguments arg1 and arg2
# m.method3.with_no_args # Do not allow method3 with no arguments
# end
