Method: Rtml::Test::Screen#possible_variants

Defined in:
lib/rtml/test/screen.rb

#possible_variants ⇒ Object

Returns an array of Hashes representing all possible non-user interaction-requiring variants from this screen. These are returned regardless of whether user interation is required at this time.

The hashes are laid out thusly:

{ :uri => "destination_uri", :key => "hotkey", :timeout => "seconds", :lo => "left_operand",
  :op => "operation", :ro => "right_operand" }

Note that some of these keys may be omitted, according to the TML rules for the variant element.

For TML next elements, all keys except :uri are omitted.
