Rails environment not taken into account when running tests

[YoranBrondsema]

I have a dedicated ci environment for running the tests on Codeship. Before starting all the tests, I explicitely set RAILS_ENV to ci. When running bundle exec rake parallel:create and bundle exec rake parallel:prepare, the databases in the correct environment are prepared. However, when running the tests with SPEC_OPTS='--tag ~js' bundle exec rake parallel:spec (I exclude Capybara integration tests), it executes some tests in the test environment. This is the output (I can detect the environment by the deprecation warning for dotenv):

Auto-loading of `.env.ci` will be removed in 1.0. See https://github.com/bkeepers/dotenv-deployment if you would like to continue using this feature.
4 processes for 82 specs, ~ 20 specs per process
Auto-loading of `.env.test` will be removed in 1.0. See https://github.com/bkeepers/dotenv-deployment if you would like to continue using this feature.

Is this a bug? Or do I miss something in order for all processes to run in the ci environment?

afaik it's not being forced anywhere, only doing RAILS_ENV || 'test',
maybe drop a puts into tasks / def rails_env and see what is going on ...

Hmmm yeah I see. I also added looked at what the value is of ENV['RAILS_ENV'] in ParallelTests::RSpec::Runner.run_tests but it's set at the correct value. Now I'm wondering where that process is coming from that executes in the test environment...
