ActiveRecord/Supporty-4.1, undefined method `assertions'

Rails
1

If there is a list devoted to ActiveRecord problems then I would
appreciate
a redirect. In the absence of same I need some assistance with part of
RoRs stack, namely ActiveRecord and the testing thereof. I have a cli
project which only uses AR-4.0 and whatever other stuff that gem pulls
in.
I am trialing the project witjh AR-4.1 and I am getting this error when
I
try to run my cucumber features:

  undefined method `assertions' for #<String:0x00000003ba4688>

(NoMethodError)

`block in <top (required)>’

I googled for this and found a couple of tangential references relating
to
a change in minitest. However, the fix appears to be somewhat dated and
in
any case this is not a full RoR stack so rspec-rails is not applicable.

This problem is caused by a change in minitest 5.0 documented here:

You can no longer `include Minitest::Assertions` · Issue #286 · minitest/minitest · GitHub

is fixed by using: gem “rspec-rails”, ‘~> 2.14.0.rc1’
in the gemfile.

Researching this further indicates that setting the version of minitest
to
~> 4.0 would fix the problem but alas, AR-4.1 requires minitest-5.1 +

Bundler could not find compatible versions for gem “minitest”:
In Gemfile:
minitest (~> 4.0) ruby

hll_th_cadex_xfer (>= 0) ruby depends on
  activerecord (>= 0) ruby depends on
    activesupport (= 4.1.4) ruby depends on
      minitest (5.1.0)

Which raises the question as to why, exactly, using an ORM gem demands
that
one install a particular testing framework that one may have no other
use
for. I do not use Rspec either but Aruba pulls that in and, as Aruba
is a
testing framework, I have to accept that. But an ORM?

In any case, is there a way around this?

The underlying issue is mentioned here in Minitest:

Whatever is including the assert functions needs to also define the
assertions accessor.

Hard to advise further without seeing the relevant code in
hll_dbms_steps.rb.

The relevant code seems to be:

# features/step_definitions/hll_dbms_steps.rb

def find_table_model_for( tname )
  tname = tname.gsub(/ +/,"_").downcase.singularize.camelcase
  expected = true
  actual = defined?( tname )
  message = "Expected #{tname} model class but it is not defined"
  assert( ( expected == actual ), message )
end

When /should have (?:a|the) table (?:name|call)ed "?(\w+)"?/ do |tname|
  find_table_model_for( tname )
end

For now we seem to worked around this problem by specifying the
following code
in a cucumber support file:

require ‘minitest/autorun’
require ‘test/unit/assertions’

World( Test::Unit::Assertions )

require ‘minitest’
module Minitest
attr_accessor :assertions
end

At least, things are no longer blowing up as soon as the feature run
starts.
It is yet to be determined whether this is a real fix as we have run
into some
other issues with AR-4.1 vis a vis code that runs fine with AR-4.0.
