Show the full class definition, including the method definition of 'test'.

It Works For Me [TM]:

irb(main):001:0> module Action
irb(main):002:1> class Email
irb(main):003:2> def self.test
irb(main):004:3> puts "Wibble"
irb(main):005:3> end
irb(main):006:2> end
irb(main):007:1> end
=> nil
irb(main):008:0> Action::Email.test
Wibble
=> nil

Note that you don't necessarily need to use 'eval':

irb(main):011:0> klass=Action.const_get('Email')
=> Action::Email
irb(main):012:0> klass.test
Wibble
=> nil
