Instantiating one of each object type

ruby-talk
1

Hi all,

I want to create an array of one of each class in ruby for testing purposes in pseudo-code I kind of want...

ObjectSpace.each_object(Class) do |c|
  c.send(:new) # I want to instantiate here and store the resulting objects in an array
end

Ok so I can half do it, but I need to dynamically send the correct arguments for each objects initialize method - any good ideas?

You gogin to have trouble instatiating without know what it is. Try
#allocate:

  objs = []
  ObjectSpace.each_object(Class) do |c|
    objs << c.allocate
  end
  p objs

There should at least be a rescue clause as not every class supports
#allocate:

ObjectSpace.each_object(Class) {|cl| cl.allocate}

TypeError: allocator undefined for Binding
        from (irb):14:in `allocate'
        from (irb):14
        from (irb):14

Kind regards
