def __cucumber_invoke(name, multiline_argument=nil) #:nodoc:
  begin
    step_match = @__cucumber_step_mother.step_match(name)
    step_match.invoke(multiline_argument)
  rescue Exception => e
    e.nested! if Undefined === e
    raise e
  end
end

#announce(announcement) ⇒ Object

Output announcement alongside the formatted output. This is an alternative to using Kernel#puts - it will display nicer, and in all outputs (in case you use several formatters)

Beware that the output will be printed before the corresponding step. This is because the step itself will not be printed until after it has run, so it can be coloured according to its status.

end

#inspect ⇒ Object

The default implementation of Object#inspect recursively traverses all instance variables and invokes inspect. This can be time consuming if the object graph is large.

This can cause unnecessary delays when certain exceptions occur. For example, MRI internally invokes #inspect on an object that raises a NoMethodError. (JRuby does not do this).

A World object can have many references created by the user or frameworks (Rails), so to avoid long waiting times on such errors in World we define it to just return a simple String.

end

#pending(message = "TODO") ⇒ Object

Mark the matched step as pending.

      yield
    rescue Exception => e
      raise Pending.new(message)
    end
    raise Pending.new("Expected pending '#{message}' to fail. No Error was raised. No longer pending?")
  else
    raise Pending.new(message)
  end
end

#table(text_or_table, file = nil, line_offset = 0) ⇒ Object

Returns a Cucumber::Ast::Table for text_or_table, which can either be a String:

table(%{
  | account | description | amount |
  | INT-100 | Taxi        | 114    |
  | CUC-101 | Peeler      | 22     |
})

or a 2D Array:

table([
  %w{ account description amount },
  %w{ INT-100 Taxi        114    },
  %w{ CUC-101 Peeler      22     }
])
