I have a Rails 3 integration test which tests my routes. It contains tests such as:
assert_routing(
"/#{@category.url.path}/#{@foo.url.path}",
{ :controller => 'foo', :action => 'show', :category => @category.to_param, :foo => @foo.to_param }
)
I would also like to test a case where no routes should match. Obviously, testing generation has no meaning in this case, so I just need the inverse of assert_recognizes. I'd like to be able to do something like this:
assert_not_recognized('/adfhkljkdhasjklhjkldfahsjkhdf')
Any ideas, short of wrapping assert_recognizes in an assert_raises block (which is actually not so terrible, now that I think about it)?
There is a similar way for checking this in Rails 4 by asserting on the UrlGenerationError exception:
def test_no_routes_match_when_neither_foo_nor_bar_exist
assert_raises(ActionController::UrlGenerationError) do
get '/category/this-is-neither-a-foo-nor-a-bar'
end
end
By calling #recognize_path you wont receive a false. Instead you'll get an error, but then you found the clue you were looking for.
test "No routes match when neither_foo_nor_ bar exist" do
begin
assert_not(Rails.application.routes.recognize_path(
'category/this-is-neither-a-foo-nor-a-bar'))
rescue ActionController::RoutingError => error
assert error.message.start_with? "No route matches"
end
end
I ended up doing this:
def test_no_routes_match_when_neither_foo_nor_bar_exist
assert_raises(ActionController::RoutingError) do
assert_recognizes({}, '/category/this-is-neither-a-foo-nor-a-bar')
end
end
Slightly silly, but it gets the job done.
Note that this does not work with Rails 4. See the answer below for a Rails 4 solution.
