assert_valid in unit tests after upgrade to rails 2.3 doesn't work

def test_valid     assert_valid State.first   end

Error: test_valid(StateTest): NoMethodError: undefined method `assert_valid' for #<StateTest: 0x7f0d60750318>

I see that test_valid is now in ActionController::Assertions::ModelAssertions. Does this mean that test_valid is designed to be used i ActionController tests only?

I can change my assert_valid(State.first) into assert (State.first.valid?) but assert_valid prints meaninful failure messages, unlike assert which just tells me "nil is not true". How can I use assert_valid in my unit tests? My test classes declared something like this: class StateTest < ActiveSupport::TestCase

Having the same problem here. But still didn't find any solution.

Ok, so

Rails Guide Testing Rails Applications — Ruby on Rails Guides para 3.5 says it exists - I guess the guide needs amending?

It was deprecated at 2.2.2 - "assert_valid is deprecated. Use assert record.valid? instead" see http://github.com/rails/rails/commit/d4754677a34d34d4a0955a04f2cc6571bdc5e82d and https://rails.lighthouseapp.com/projects/8994/tickets/1470-assert_valid-undefined-in-edge-activesupporttestcase

I didnt want to go change all my tests just at the moment, so putting assert_valid in my test_helper gets me over that for the moment. Bit of a time waster, since I was going from 2.0.2 to 2.3 so had not seen the dep error.

def assert_valid(record)   assert record.valid?, record.errors.full_messages.join("\n") end
