[Rails] Re: How to test the layout of a controller?

First off, resolving my own issue:
Apparently, you can use "assert_template" to test the layout. In my
case, I could do
-
assert_template 'static/home','layouts/application'
-
which would work.

With regard to the idea about testing behavior alone:

That makes a lot of sense. A lot. My question, however, is about how
there must be a line to draw. If you were to test that the view has
the content you want, wouldn't you HAVE to be testing implementation
to an extent, as your view contains tags like e.g. <div class='span-5'
id='main'>, and you'd be testing for e.g. a div with id 'main'? It's
just not clear to me how...

Could you elaborate, maybe? Also, as I'm just getting started
testing, I guess it's good to know now: Is it okay to use Shoulda and
factory_girl_rails to handle all my testing? Or is rspec / cucumber
absolutely necessary? (I don't feel like changing .... but I guess I
need to know)
