Rails - May 2006 - Testing How To Question

I''m using the functional test for a method like this:

def test_create

  post :create, :phase => ''copynew'', :id => 1
  assert_response :success
  assert_template ''create''
  assert_tag :content => ''New Item''
		
  assert_not_nil @item
end

This posts a request to the create method in the controller.  Is there  
any way to look at the variables and objects that were created in the  
controller by this post?  It looks like you are only able to examine the  
resulting html output.

Is that more of a unit test thing rather than a functional test thing?

And finally, if it is a unit test thing, how do I pass a set of params  
to a controller method call from a unit test?

I''m just starting out myself, but I think this is covered in the  
AgileWDR book on pages 162 and 164. Take a look at the #assigns  
method call.

Ex.
	assert_equal assigns(:some_var), <what the value should be>

You can examine variables in either kind of test. It''s not limited to  
one or the other.

I''ve never done this but I assume it works the same way as the  
opposite (func test to unit test param passing). Maybe someone else  
can chime in here.

In unit test you never call the controller. Unit test are used to test 
the model only. For controller testing, use functionnall test instead.
