Yes you can use step definitions to do this, but I would avoid nesting the
steps and actually make the direct calls e.g.
Personally I now think nested steps are evil - but thats another story :)
If the items are fields in forms I'd just assume their presence and fill
them in in a step e.g.
when /^I fill in foo form correctly$/ do
fill_in foo.wibble, :with => "wibbling"
However before I can do this I'm thinking that a view spec that says the
form has a wibble field would be useful, concise and expressive. The feature
drives what you do with the view, and the view spec specifies whats in the
view. This matches the loop within loop workflow in the rspec book.
Having said all this I haven't actually done this in practice yet, going to
try it on my next view.
By the way its nice to find a fellow soul who appreciates the wonderfully
expressive power of the word 'wibble'!
