<a name="sample-parallel-test-ruby-cucumber"></a>

The following is sample of a `buildspec.yml` that shows parallel test execution with Cucumber on an Linux platform:

```
version: 0.2

batch:
  fast-fail: false
  build-fanout:
    parallelism: 5
    ignore-failure: false

phases:
  install:
    commands:
      - echo 'Installing Ruby dependencies'
      - gem install bundler
      - bundle install
  pre_build:
    commands:
      - echo 'prebuild'
  build:
    commands:
      - echo 'Running Cucumber Tests'
      - cucumber --init
      - |
        codebuild-tests-run \
         --test-command "cucumber" \
         --files-search "codebuild-glob-search '**/*.feature'"
  post_build:
    commands:
      - echo "Test execution completed"
```
