Rspec VerifyingDouble object_double wrong number of arguments


Rspec VerifyingDouble object_double wrong number of arguments

should help you out Your SomeClass#initialize method requires 2 arguments. You are calling SomeClass.new with no arguments. Ruby raises an ArgumentError in these circumstances. You need to either pass 2 arguments to SomeClass.new, change your initialize definition to be tolerant of no arguments being passed, or use a different kind of RSpec verifying double that doesn't require you to create an actual SomeClass instance. For example, you could use instance_double(SomeClass).
code :

hop of those help? Instead of "find_by_id" (which by the way is deprecated...) you can just use find and rescue from the exception. This is much simpler.
code :
def show
  begin
    @message = Message.find(params[:id])
  rescue ActiveRecord::NotFound
    do whatever you want on missing message
    return
  end
  # rest of code
end

Does that help You have spelt initialize wrong in your Class definition (Missed the i after the n.)
Therefore your class still has the default constructor as you haven't overridden it. The default constructor takes no arguments so is complaining when you try and pass 3.
