Run rake spec in parallel

By chance has anyone already running the rake spec tasks in parallel?

We run our tests in parallel during CI, and also during local development. To try it out, you can run:

bin/rake parallel:create
bin/rake parallel:migrate
bin/turbo_rspec

Thank you, this is pretty cool!

To make it run in my local dev environment I first had to fix:

ERROR: permission denied to create database 
Tasks: TOP => db:create
(See full trace by running task with --trace)
PG::InsufficientPrivilege: ERROR:  permission denied to create database
Couldn't create 'discourse_test_32' database. Please check your configuration.
rake aborted!
ActiveRecord::StatementInvalid: PG::InsufficientPrivilege: ERROR:  permission denied to create database

Caused by:
PG::InsufficientPrivilege: ERROR:  permission denied to create database

# switch into container
d/shell_root

# inside container - root@discourse:/#
sudo -u postgres psql

# psql - postgres=#
ALTER USER discourse CREATEDB;
exit

# inside container - root@discourse:/#
exit

And now it works even inside the container:

d/rake parallel:create
d/rake parallel:migrate
d/exec bin/turbo_rspec
