Strange assertion result in functional test

I am testing the ‘settings’ action, in my Blog controller

def settings
@blog = Blog.find(params[:id])
@setting_form = “settings”
end

I wrote the following assertions :

get :settings, :id => @blog[:id]
assert_not_nil assigns(:blog)
assert_equal "settings", assigns(:setting_form)

but I get a failure on the assigns(:setting_form) assertion, with diff
nil … strange ?? what’s up ? any clue ?
<> expected but was
<>
diff:
nil

thanks for our feedback

[SOLVED] assigns(:blog) is OK because @blog is created in the test
setup, and the get :settings was DENIED … so the action was never
completed
added the necessary checking in my test :

sign_in  @admin_west
ability = BackofficeAbility.new(@admin_west)
assert ability.can? :settings, Blog
get :settings, :id => @blog[:id]

and now it passes through
