Test redirect_to fails

Hi

I have a weird issue on functional testing
Here is the redirect I have in my controller:

 redirect_to :controller => "/param/user", :action => :edit, :id

=> @current_user.id

And here is my functional test:
assert_redirected_to :controller => “/param/user”, :action
=> :edit, :id => users(:vincent).id

And when I run test I have this error (users(:vincent).id = 4)

response is not a redirection to all of the options supplied

(redirection is <{:controller=>"/param/user", :action=>:edit, :id=>4}

), difference: <{}>

AThere is no difference but it raises a failure.
Did I do something wong?
