`uninitialized constant ActiveSupport` with Minitest runner

[rubendinho]

Hi -

I'm getting the below error running bundle exec rake knapsack:minitest in both my CI and development environments:

Tasks: TOP => knapsack:minitest_run

I am on Rails 5.2.1, knapsack 1.16.0 and Ruby 2.5.1.

Here is my Minitest configuration:

#test_helper.rb
ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'

require 'knapsack'
knapsack_adapter = Knapsack::Adapters::MinitestAdapter.bind
knapsack_adapter.set_test_helper_path(__FILE__)

class ActiveSupport::TestCase
end

I am not running into any problems with the Rspec runner.

I was trying to reproduce this problem and I'm not able. Maybe it's specific to your project or the order of loading files by your project. I guess somehow Rails environment was not loaded properly.

https://github.com/KnapsackPro/rails-app-with-knapsack/pull/8

Here is test_helper.rb from example rails project https://github.com/KnapsackPro/rails-app-with-knapsack/blob/master/test/test_helper.rb

Please make sure you added the following line at the top of the test/models/article_test.rb file.

require 'test_helper'

I'm closing this for now. Please reopen if you need more help.
