Cucumber test suite too slow for Travis

Question

I have a cucumber test suite for my rails app, comprising around 500 Scenarios with about 5000 Steps between them. I have set up my github repository to use Travis-CI, using the following `.travis.yml`. ``` language: ruby rvm: - "1.9.2" script: - RAILS_ENV=test bundle exec rake db:migrate --trace - bundle exec cucumber -f progress -r features features/cards/base_game - bundle exec cucumber -f progress -r features features/cards/basic_cards - bundle exec cucumber -f progress -r features features/cards/intrigue - bundle exec cucumber -f progress -r features features/cards/seaside - bundle exec cucumber -f progress -r features features/cards/prosperity - bundle exec cucumber -f progress -r features features/cards/interactions before_script: - cp config/database.travis.yml config/database.yml - psql -c 'create database dominion_test' -U postgres ``` I have split the cucumber execution up as Travis was throwing Out Of Memory if I just ran `bundle exec cucumber` to run all the cases. Howeve…

Accepted Answer

I found a solution, after much googling, at this page of Travis' docs.

Basically, it's allowed (recommended, even!) to parallelise the runs. With the following `.travis.yml`, I end up with six concurrent jobs, none of which takes over 15 minutes, and which therefore all run to completion:

```
language: ruby
rvm:
  - "1.9.2"
env:
  - CARD_SET=base_game
  - CARD_SET=basic_cards
  - CARD_SET=intrigue
  - CARD_SET=seaside
  - CARD_SET=prosperity
  - CARD_SET=interactions
script:
  - RAILS_ENV=test bundle exec rake db:migrate --trace
  - bundle exec cucumber -f progress -r features features/cards/$CARD_SET
before_script:
  - cp config/database.travis.yml config/database.yml
  - psql -c 'create database dominion_test' -U postgres
```
