Setting up parallelisation on environment other than 'test'

[zhirgis]

So I'm working on a project that has both unit tests and so called E2E tests in same repository. For these two purposes we're using different environments 'test' for unit and 'e2e_test' for e2e tests. I was trying to parallelize e2e_tests, I have database.yml setup for the environment, and was trying to run rake tasks with specified environment "RAILS_ENV=e2e_test bundle exec rake parallel:prepare" however it seems like it still always runs on 'test' environment.
As I understand, env is always selected here: https://github.com/grosser/parallel_tests/blob/master/lib/parallel_tests/tasks.rb#L9

Is there a way to override the environment and work on a different one than 'test'?

you can try running prepare in parallel like this
or run drop+create in parallel, but then you don't get the fixtures

if rails "prepare" itself does not hardcode the rails-env then we could remove the hardcoding here too, but I think it does

Sorry it took so long to get back, but yeah, I was not able to achieve this. As can see in the commit of the line, environment is always forced as 'test' 135673d
