travis configuration for laravel packages

I'm trying to piece together a configuration for laravel packages. Does anyone have experience with this for laravel 5.1+?

• travis configuration for laravel 4.2
• another one for 4.2

Both use the ability to append to the configuration from an environment specific config directory. Is there a way to do the same in 5.1+?

So far I have, but before I start testing functionality and need thousands commits to fix this, perhaps people with travis experience can shed some light on this setup:

language: php

php:
  - 5.5
  - 5.6
  - hhvm

before_install:
  - composer self-update

addons:
  hosts:
    - system.hyn.me
    - tenant.hyn.me

install:
  - composer create-project laravel/laravel
  - cd ./laravel
  - composer require hyn-me/multi-tenant ~0.1.0
  - composer update


before_script:
  - cp .env.travis .env
  - export APP_ENV="testing"
  - php artisan migrate -q -n --path ./vendor/hyn-me/multi-tenant/src/migrations
  - cd ./vendor/hyn-me/multi-tenant

script: phpunit

Trying to make this work for http://github.com/hyn-me/multi-tenant
