ruby 2.2.0 rails 4.0.13 and rspec 3.1.0 cannot load such file -- test/unit/assertions

[waynehoover]

Hello, I'm getting this error, any ideas why? `require': cannot load such file -- test/unit/assertions

~/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/activesupport-4.0.13/lib/active_support/dependencies.rb:229:in `require': cannot load such file -- test/unit/assertions (LoadError)

The stack trace points to this line in my spec_helper:require 'rspec/rails'

I figured it out.

You have to add the test-unit gem to your gemfile: gem 'test-unit'

This is related to #1264. It should be fixed in the next release. You should just need the minitest gem, it sets up the proper test unit shims.

I had to add both, test-unit and minitest gems to make this work. So both are fine or am I doing anything wrong here?

[cupakromer]

@rohandaxini you should not need the test-unit gem unless you have something else that is loading test unit specifically. The minitest gem handles setting up the proper constant aliases. What problem did you run into?

Thanks for your note @cupakromer
Actually I was facing this error while running my tests (rspec test suite) on local.

/my_computer/.rvm/gems/ruby-2.2.0/gems/activesupport-3.2.18/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- test/unit/testcase (LoadError)

This has happened recently when I upgraded to Ruby2.2.0, earlier I was not facing this error on Ruby 2.1.2 or 2.1.5

I found this git issue and thought to add test-unit after other error went away by adding minitest
But I am sure, I am doing something wrong that has led me to add both these gems. Thoughts ?

btw, while upgrading to Ruby 2.2.0, I have no other code change except in Gemfile. My new entires in Gemfile are:
ruby '2.2.0'
gem 'eventmachine', '1.0.4'

Accordingly my Gemfile.lock has changes only related to these 2 gems.

[cupakromer]

Thanks for the background information. Have you tried just removing test-unit from your Gemfile and only having minitest?

[cupakromer]

Ok, I just noticed your gem file location. You are running Rails 3.2 not Rails 4.0 which is what this issue is about. Rails hasn't officially started supporting Ruby 2.2 on Rails 3.2 yet (you can see they are working on it in the git history). As such rspec-rails has started to prepare for this in #1277. However, as it stands now we will only be supporting the latest patch release (and above) which has the fixes for Ruby 2.2 support.

Thanks a lot for your detailed note @cupakromer This is really helpful and I now understood the problem due to Rails 3.2.

Sorry my bad :(
Yeah saw those links and glad to see the progress.

Hi there, thanks for rspec and everything :) Could we get a release soon-ish please? This problem is still really bugging us so a release soon-ish would really be appreciated :)

[myronmarston]

@PragTob -- I'm planning on releasing 3.2 tomorrow or early next week. If there's no 3.2 release in the next 7 days, you have my permission to hound me until it's out :).

[PragTob]

Thank you very much @myronmarston - you're awesome so much ❤️ ❤️ ❤️ 💚

[jasnow]

@myronmarston - I can use the "3.2 fix" too.

[PragTob]

@jasnow 3.2.0 was released on the third of February, you should be able to install it.

Thanks Myron!

Not sure why a question on Rails 4 devolved into Rails 3 is broken but see OP's solution

You have to add the test-unit gem to your gemfile: gem 'test-unit'
