Rails and RSpec: `rake spec` fulfills all specifications twice

I created a new Rails 4 application using RSpec. But at startup, rake rspecall examples run twice:

rake spec
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

I found some other (old) questions about this, but could not find a solution for me. How should I try to debug this? The launch rspecworks like a charm, but I really want to know what the problem is.

Here's mine spec_helper.rb: https://github.com/jmuheim/transition/blob/master/spec/spec_helper.rb

And here is the original Rails project: https://github.com/jmuheim/transition

Refresh

I found that the specrake task seems to be defined twice (note the one /that shares the description of each task):

$ rake -T | grep spec
...
rake spec                               # Run all specs in spec directory (excluding plugin specs) / Run RSpec code examples
...

Run all specs in spec directory (excluding plugin specs), Run RSpec code examples.

Run RSpec code examples , rspec/core/rake_task.rb. Run all specs in spec directory (excluding plugin specs) , rspec/rails/tasks/rspec.rake.

CI

rspec spec Rails , RSpec CI. , :

bundle exec rake

RAILS_ENV. , spec_helper.rb ENV["RAILS_ENV"] ||= 'test'.

But on CI, ENV already has a RAILS_ENV=testsuite that also leads to the specRails task , which leads to double test runs.

Eventually:

bundle exec rake                  # => 1 test run
RAILS_ENV=test bundle exec rake   # => 2 test runs

Fix

Clean up task(:spec)after loadingRails.application.load_tasks (if you want to define the task yourself :spec).
