Rails - May 2005 - create and functional testing

I''m trying to test /foo/create action. I read all the testing howto
and also this:
http://wiki.rubyonrails.com/rails/show/HowtoFunctionalTestACreateAction
but I can''t get it work. post() passes but assert_redirect_to
redirects elsewhere (due to false return value of foo.save), my
problem is... how can i know what''s happening into the test function?
Tried using a breakpoint statement but since the object has not been
saved in the model i don''t know how to look at it.

Any solution?

A couple of thoughts:

If your model fails to save when given specific values you can unit test 
the model with those values outside the scope of the controller(IE a 
unit test instead of a functional test).

Still, you can probably track down the unsaved record in the function 
test, check within the @response object.

Also, you can call a breakpoint anywhere you want, so you might get a 
better vantage point on whats going on by breakpointing from within the 
controller being tested or even the model itself.

hth.

Right, I already have some unit testing for the model. Gotta improve
it. Turn back to fixtures :)

Ah, ok. Thanks!

I''m trying to dig into @response test object (test the same stuff in
the model works) and understand how functional test works but I don''t
get it :(

here''s my object in a breakpoint right after the "post"
method

It seems that at some time the object attributes become nil but why... and when?

I can''t really make sense of the exact problem you''re having
from the
response, but one thing did stand out.

The @response.env contains the following:
@env={
 
"REQUEST_URI"=>"/paste/create?paste=created_onWed+May+11+19%3A39%3A42+CEST+2005bodydef+foo+endlanguageRubyauthoranonymousdescriptiontest",

  "SERVER_PORT"=>80,
  "REQUEST_METHOD"=>"POST"
}

Note that the request_uri is carrying your params on the url (as in a 
GET request) but you''re testing with the POST method. I don''t
know if
it''s directly related to your error, but it doesn''t seem
right.

I tried calling post() manually in a debug session (with breakpoint)
and I get the same problem. I dug into
rails/actionpack/lib/action_controller/test_process.rb but I''m not
able to know if it''s a bug or not. What I''m missing?

This is the code snippet (placed in the right place in a test_ method
into the functional tester file)

    post :create, { 
      :paste => { 
        :author => "anonymous",
        :language => "Ruby",
        :description => "test",
        :body => "def foo end",
        :created_on => Time.now
      }
    }

Strange. I''m not sure either. Does breakpointing from within the 
controllers context yield any useful info? Eg: Does @params contain the 
paste hash? can you create and save a model with it?

if I test manually in the unit test section all works

The fact that the controller isn''t seeing the given parameters is the 
root of your problem. I wonder if it''s not happy with your use of 
symbols as keys?

Tried also with plain strings but the results are the same :(
